Military Sleep System Sleeping Bag Review - Survival Gear

[@michaelmccoy2698]

Brian, New subscriber, retired military. Good review. I use my mss with a foam thermarest ridgerest solar pad inside the bivi under the sleeping bag, inside my hennessy survivor woodland camo zip hammock. A little heavy for long range backpacking but, never been cold, never been wet. Take care stay safe O.P. ( Olde Phart)

[@SurvivalOnPurpose]

Than you for your service! I am now using the Hennesssey Jungle Explorer Zip with the slide in thermal pad and it is pretty warm.

[@MrWmburr7]

Brian, great video. You explained each piece of equipment, showed how they marry together, and the benefit of the bag as a whole. I bought one new, but have never used it. Now I'm old and sick, so time to pass it down to someone who might appreciate having one.

[@islandboypopo]

This was the most cozy sleeping bag system I've ever been in. Cold nights in Afghanistan, and in the mojave desert, and this thing got the job done. I will say it's rather heavy, but that is the only downfall. I miss it so much I ordered my own.

[@SurvivalOnPurpose]

Bo Fa'aita Thanks for serving! Yeah, I used mine this weekend in my Hennessey Hammock while camping with the Boy Scouts. It got down in the low 40s and I was toasty, which is tricky in a hammock.

[@sivispacemparabellum4873]

Bo Fa'aita same here. I missed mine so much that I just had to purchase my own since I couldn't get away with snagging it before my time was up. I still have my woobie though and managed to keep my USMC ILBE pack along with my assault pack that attaches to it to. What branch did you serve in by the way?

[@playinem121]

Bo Fa'aita...Agreed! And it gets plenty cold in Afghanistan.

[@billy_h_bonney2097]

I brought mine home with me and my wife is such a bed sheet hog that one night I was being a smart a$$ and threw my sleeping bag on the bed. She said "what are you doing?" I climbed into the bag and said good luck steeling these covers!!". Dude!! Best nights sleep since Baghdad rotfl. Im so glad supply lost their records of issuing my TA-50. The only things I returned was my Kevlar and my IBA. Everything else I brought home with me :D

[@hartzogLovesScience]

10lbs isn’t it

[@joeyjones9041]

Mine and my wife's came with a 9 strap compression sack. 6 that go long ways, and 3 that go short ways around the round part. You definitely want the 9 strap sack, it compresses it much better. They are about 20 bucks on ebay. I bought the whole 4pc system used in excellent condition for $140. I love it, it's my favorite piece of gear.

[@SurvivalOnPurpose]

Cool

[@wanderingcalamity360]

I'll keep an eye out for that one. Probably easier to get it compressed.

[@billy_h_bonney2097]

if you want to compress the sleeping bag more, you can sit on the bag as you pull up on the compression straps. Also when you are sleeping in one in cold or extreme cold weather, once you get in it you are supposed to strip off your uniform,(clothes), and keep them inside the bag with you. This allows your body to breathe so that you are not sweating in your clothes, and keeps your clothes warm for when you get up in the morning.

[@SurvivalOnPurpose]

Thanks

[@davidpolaczek3614]

I wish I knew this sooner

[@jedi_drifter2988]

I have always had good luck getting my compression bags smallest when after pulling the straps tight, you can then sit on the top side of the bag and continue to tighten the straps. Let your weight and gravity do the work .

[@SurvivalOnPurpose]

+Jedi_Drifter yep

[@bennyvoncannon197]

Brain I think this was the best yet. Don't think I have seen anyone show the whole system from take down put together and stuff to all in one video. Very good thanks a bunch.

[@SurvivalOnPurpose]

benny voncannon Thanks Benny. I hadn't either so I wanted to show the whole process. Maybe a little boring but hopefully it helps.

[@sivispacemparabellum4873]

These also come in a larger sizes for taller individuals. When purchasing said item,be sure you get the one that fits your size so that it can be used to it's full extent. I'm about 5' 8" and have the size listed as the one in this video. They can be purchased on eBay for a great price and in a variety of conditions with A being in tip top shape,and B being slightly used,and C having small holes/tares/rips,missing buttons or zippers that may not function but can be repaired. These sleep systems are an excellent item to add to your bug out bag or just for every day camping with the family. I would highly recommend the purchase of this sleep system for a variety of reasons. Don't forget to buy either a yoga mat to tuck inside of it or a self inflating mat for extra added comfort. Great video made here by the way and you won't regret purchasing such an item. In sime cases,most of these come with directions on how to dress properly for the environment you are in so that the MSS can be used to it's full potential when dressed properly in whatever climate you are in.

[@SurvivalOnPurpose]

I'm glad got the right size

[@VE3FAL1Fred]

I have this MSS and the Canadian MSS, the US version does me well in my hot tents. My Cdn system is much larger and heavier and is good for much colder temps, but again your clothing you sleep in , and your shelter will make all the difference, a good pad and cot or insulation on the ground make all the difference. Will be using my US MSS this weekend at the prospector tent....cheers Fred

[@williamwright82164]

To my understanding when you combine the patrol bag and the intermediate cold bag it brings the protection to -25.

[@576chachacha]

Thanks for the review. I've got two of these, one from the Army and one bought new/surplus. Since they've introduced a different color scheme and upgraded version these older ones with the green/black/woodland patters are going for real good prices new. It's not perfect, the tech is two decades behind, there's a lot of stuff out there that's lighter by a big margin. The stuff sack is just bad, there's no top/bottom cover to compress from that direction. Except for the patrol bag it really is too heavy a system for backpacking, but that green bag with a better sleeping pad [not the green one on the vid] should keep you warm down to 35 degrees or so. The whole thing is great for car camping or hunting trips.

[@SurvivalOnPurpose]

It is indeed a little heavy but it works

[@mickeyauthement6898]

Finally found one listed as in "Excellent Condition" for under $100. Am happy you did a video on the complete system especially putting the assembled system into the stuff sack. Had been wondering if that was a possibility or not.

[@SurvivalOnPurpose]

Barely ;-)

[@KatzOhki]

I have one of these and I absolutely love it. Thing is too dang warm for me almost, I recon i would sleep fine down to -30 no problem.

[@SurvivalOnPurpose]

+KatzOhki Pretty heavy too.

[@jwall3873]

Darn good vid...learned a lot... Keep up the good work!

[@toma674]

I don't know how this video escaped me,but that is a great system Bryan..boy,mother nature really knows how to mess with us,don't she? Very thorough review and demo.This would be great to keep in the vehicle for the winter.

[@SurvivalOnPurpose]

tom a I need to get a weatherproof camera but all the Go Pro type cameras have those wide angle lenses that make everything look all distorted. And, yes, the MSS is perfect for that. I came very close to being stranded last winter by the gigantic 4" snowfall that hit Georgia but I wasn't too concerned because I had what I needed to make it through the night in my truck. This winter I'll be even better prepared ;-)

[@sipapito]

Thank you for your video;I got this system new and its warm but way heavy and bulky I wish it lighter and smaller!

[@SurvivalOnPurpose]

+Tonauac/Teonewhopossesseslight /Nahuatl Wouldn't that be great.

I’ve got two of these they do have a camp goretex bag that the stuff bag goes into there nice also I use mine every winter at my off grid cabin up in the mountains so far the patrol and the goretex bivy has been great you got a good Syst there it will do you well sir !

[@mr.delacruz559]

smart putting it in assembled in the bevy because of your carrying this and if it ever gets wet the bevy will keep the inner sleeping bags dry. that's how I put my sleep system in its compression pouch. Great video!

[@SurvivalOnPurpose]

Good idea

[@michaellester5901]

dose very well in a hammock I slept in mine at -9°F with an under quilt

Love YKK zippers. I try to make sure I get the YKK Vislon zippers on all my jackets. Lenzip is also a good quality U.S. made zipper. I have them on my tool bags. Thanks for posting.

[@MrPatagonicus]

I purchased one of these just about a month ago. It was listed as used, but it came in like new condition, straight from an USAF base in Germany. I just took it up into the Sierra Nevada over the weekend on a backpacking trip, and it went great, using the patrol bag and the bivy. No problems at all sleeping at around 9,000 ft.

[@SurvivalOnPurpose]

MrPatagonicus That's good to know. I almost went with a used one, I have just been burned on stuff like that before. Glad you got a good one.

[@MrPatagonicus]

Survival On Purpose I've been burned before as well. The price was low though, and especially so seeing it arrived in such great shape. I think the quality, modular design will serve me well for quite some time. Thanks again for the review.

[@SurvivalOnPurpose]

Thanks for watching.

[@turtlewolfpack6061]

I recently got myself the Canadian version of this (all I need is the outer sleeping bag to complete the set) and although older tech, being down and the bags tie together instead of button, the bloody thing is toasty warm and the bivvy bag did its duty recently on a very wet weekend bush camp out!

[@SurvivalOnPurpose]

+TurtleWolf Pack I bet the down bags are warm. You just have to make sure they stay dry.

[@turtlewolfpack6061]

Survival On Purpose yup you do and not a good idea to store them compressed.

[@SurvivalOnPurpose]

Which is probably a good idea with all bags but I just don't have room

[@turtlewolfpack6061]

Survival On Purpose less so with synthetic bags is my understanding.

[@danielcharbonneau222]

[@samualiam9981]

I am 72 inches tall and about 240 lbs. and I fit in this entire system rather easily and comfortably. Takes a minute to get used to "mummy style" sleeping, but its worth it. Used these back in spring of 06 on Ft. Richardson, AK. They work great.

Heavy but warm

[@Rich-ni2ol]

Been using mine since it was issued, I'm in it right now, and I never noticed that drawstring. Btw, I've always put the green bag inside of the black but mostly just run the green and bivy.

[@concernedcitizen2898]

Wait, so you wrote this comment while tucked into your bag? I never thought the MSS was versatile enough to allow someone to use their smart phone.

[@Rich-ni2ol]

@@concernedcitizen2898 More versatile than a poncho and woobie.

[@rakehell404]

I have camped in this bag in a snowstorm that went down to around 15*F and was snug as a bug. It is very high quality, rugged gear that's very well thought out. One thing I did to reduce condensation was keep the bivy zipper open near my head and stuck a rolled bandana in the zipper to open a small gap. In the morning I had a little bit of frost on bivy near my head but not much. One thing I'd suggest is consider taking an air pad. The closed cell foam works pretty well but an air pad would have made a huge difference in terms of comfort and insulation. The other side of that coin is that an air pad can go flat and pads don't. YMMV

[@SurvivalOnPurpose]

Yeah, the foam bad is not really comfy. My hips hurt in the morning.

[@carolinares-q4205]

I have this system, and I can tell you great winter kit, slept in it out in open under tarp down around 15 degrees no problem, only thing if you are a large person, it is tight, don,t know if they come in diffident sizes, this will be the last sleeping bag you will buy.

[@SurvivalOnPurpose]

Darren Ledford That's good to hear. I know a lot of people may think it's expensive when you can buy a sleeping bag at Walmart for under $50 but you can spend a LOT of money on a sleeping bag without even trying so I think it's a good value. Of course it is WAY heavy of you are looking for ultralight gear.

[@carolinares-q4205]

You are right no Walmart bag and a little heavy but worth every penny. You will be happy.

[@SurvivalOnPurpose]

I'm already happy and I haven't even slept in it yet ;-)

The sleeping bags I used in the British forces were quite different as we slept with our rifles at the ready.Top half just a flap to be quickly flipped open.You can not sleep with your rifle at the ready and exit quickly in the MSS.For civilian use a fantastic bag.Slept with just the patrol bag ,now it is diving below zero I installed the inner bag and the bivi bag.A very good bang for the buck.You can not beat army surplus stuff for design ,quality and toughness and price.

Hey man just wanna say thanks for this august marathon that you're doing for us . I've been researching this mss bag for a while now and have seen a bunch of videos but your video is the first video that I've actually seen the thing put together in real time . Your video definitely has made my final decision in getting this bag.. And also want to say Thanks for representing us Georgia boys keep up the good work and also an idea for maybe future videos is to explore a little bit more on wild edibles and medicinal plants here in the North Georgia area or East Coast area , I don't know about anybody else but I'm pretty lost when it comes to those things and being that I am living in the North Georgia area I could definitely benefit from such information but like I said it's just an idea you're doing pretty good so far, so thanks again!

[@SurvivalOnPurpose]

Gbaum515 Yeah, when I was thinking about buying mine I watched a bunch of videos too. None of them seemed to show enough details so I tried to make sure mine did. I'm glad it helped you.As for the edible and medicinal plants, I was just talking to a friend yesterday about wanting to learn more about that subject. I have some good books but my knowledge is super basic. That will be a case of us learning together, which is OK by me. I said from the beginning I'm not any kind of expert, just a guy who has spent a night or two in the woods over the years and likes it.Stick with me and we'll get to it. Where do you live in Georgia?

[@opalprestonshirley1700]

[@angeluscorpion]

Brian, I have been a grunt for 12 years. For 10 of those I used this sleeping system. As a grunt it it OK by normal standards I would rate it as good. Also the green bag goes inside the black bag.

[@SurvivalOnPurpose]

I appreciate the real world feedback. Every photo I found, including the one on Tennier Industries website shows the black bag inside the green bag. Just goes to show that the folks who make gear don't always know how it will be used.

[@reconmanone]

You did it correctly, the black goes inside the green. Too many soldiers use it improperly. Also your supposed to sleep in it with minimal clothing. The bag stores your body heat to keep you warm. Too much clothing keeps the bag from doing it's job. Have used the system in -50 with nothing on. It is important to use a mat. This is from a 24 year infantry vet.

[@keithrudge]

Nice job in the review. I enjoy all of your videos.. No BS, good honest evaluation.. Keep them coming..

[@SurvivalOnPurpose]

Keith Rudge Thanks Keith. Hello up in Alpharetta. I'm in Douglasville.

[@keithrudge]

Hey Bryan, not too far away, relative neighbors.... A quick question for you, I am a native of the UK, and we only have one poisonous snake species, the Adder a. pier I think.. I have never even thought about them when hiking I. England and Scotland... Very rare to come across them. Should I be concerned her in Georgia? I am a bit paranoid about them and not sure if I should worry unduly, what has been your experience when hiking..?

[@SurvivalOnPurpose]

We 4 different types of venomous snakes here in Georgia, with several subspecies. Rattlesnakes, Copperheads, water moccasins and coral snakes. I have been hiking and camping in the Georgia woods for over 40 years and have only seen a venomous snake maybe 3 or 4 times and have never had a really close call. That's not to say it doesn't happen, it just hasn't happened to me. The most likely species you will encounter when hiking anywhere north of Macon would be copperheads or rattlesnakes. As long as you practice good hiking safety (such as stepping on top of logs instead of just stepping over them, etc) you could probably go your entire life and never see a poisonous snake in the wild. Especially if you are hiking on established trails. Having said that, the last one I saw was earlier this year at a very busy trail at Kennesaw Mountain in Marietta. We came upon a very small (8" or so) baby copperhead. Since there are always a lot of kids on that trail... I'll leave it at that. I have seen some big rat snakes on the same trail (4'-5') and that is always cool. Lots of deer there too, it's a great place to hike just not to secluded. But I digress. anyway, I wouldn't sweat it. And just remember, if you were to be bitten and envenomed, don't do the old cut and suck stuff. Just get to the hospital ASAP.

[@keithrudge]

Bryan, really appreciate the quick response. I will go with your thoughts, ie don't sweat it, but be vigilante...lol... have a great weekend.. We definitely plan to do the Kennesaw trail and there is one called iron mill trail, on red mountain, that should get the blood circulating again...;0)

[@SurvivalOnPurpose]

Brrrr

[@0ktober]

Me too, man. Just bought my first top notch hammock / tarp combo, haven't tried it yet but got an itch that I should research winter hammock camping a bit more. The temperatures in Finland are still dropping down to -10 C at nights, so I decided to put my money to good insulation and a decent sleeping bag or bags. If I get these, I'm not exactly planning to get an underquilt with them - they may (or may not) work wonders but man, are they are clunky.

[@semco72057]

I was just looking at the Marine Corps video on their sleep system and it is different and if theirs is that good then the Air Force, Army, and Navy must have a similar system as well. I never had to depend on that type of system while on active duty and glad of it. The coldest place I was stationed at was Minot, North Dakota and I was so glad to be sent to Thailand after being there a year.

[@TheBladeluster]

Awesome. Nice comprehensive review. Just purchased mine, cost me both arms and a leg to get posted overseas (guess that will leave more room in the bag). I wasn't sure how this went together properly, this has helped lots. You should mention that this sleep system should not be stored compressed though. I have heard it will ruin the systems bag-fill.

[@SurvivalOnPurpose]

+Couch Ninja I store mine compressed and I would bet the military does too. I'm sure it is better not to but many people don't have room to store theirs loose.

[@TheBladeluster]

Your probably right, however the military can afford to just get another one off the shelf at will whenever the old one is no longer any good. I made the comment because you Americans often forget about your international subscribers. I purchased this system and it cost me $150 just to get the item shipped to my country. Letting me know that keeping it in a compressed state may effect the fill would have been something that I would have wanted to know, had I not already known it. I can't afford to just keep forking out $200+ for a sleep system, I need to look after it as best I can. As for space, well, it all folds up nicely into a cardboard box uncompressed, not that much more of a hastle to store. Still, keep up the good reviews, I enjoy your channel.

[@SurvivalOnPurpose]

I understand. I was just being honest. I don't store mine uncompressed and I'm really not concerned about it. I Bet it will serve me fine for many years to come.

[@andrewbaker4890]

Hello sir Happy Thanksgiving to you and your family. I’ve been thinking about getting one of these. My question is could you get a sleep system and avoid getting a under quilt. When it comes to sleeping in a hammock in the winter.

[@SurvivalOnPurpose]

I guess that depends on you. The advantage of an under quilt is that it doesn’t get compressed by your body and lose it’s ability to insulate.

[@jkamp]

Very interested to know how this worked for you in the hammock. I'm also getting into hammock camping and am looking heavily at this system. It is a bit heavier than I wanted to go, but I love the modularity for different temps, so I don't necessarily need to take it all with. Hopefully you've gotten some use in with it. I don't really anticipate using it below high 20's... perhaps even low 30's. I'm in Arizona, so I'll be doing most of my camping around Prescott, Payson, or Sedona areas. Thanks!

[@SurvivalOnPurpose]

I have not had the chance to use mine but once in my hammock. The temps were in the 40s and I was fine. I did use the whole system on the ground in. Mid 20s temps with just the bivy and no tent and I was toasty. I plan to use it in March in my hammock so I'll try to do a follow up after that.

[@jkamp]

Survival On Purpose Awesome. Thanks for the reply! Sub'd so I can catch your update! I went ahead and ordered one anyways. Found grade 1 'excellent' condition one on ebay for a little over $100. Looking forward to giving it a try.

[@SurvivalOnPurpose]

Joshua Kampmeier You'll be warm.

[@CRM08]

I purchased one of these new. Tried it overnight in 15°F weather, it was a miserable experience. I wouldn't mind the weight if it was warmer. I'm going to try a Recon 4 sleeping bag at only 3.5 pounds. I may still freeze but at least it will be much lighter.

[@SurvivalOnPurpose]

Did you have a good ground pad? I slept in mine in the low 20s using both backs and the goretex bibs on the green military pad and I was warm enough. It wasn’t comfortable because I hate sleeping on the ground and my hips hurt from that but I wasn’t really cold.

[@komrad40]

Thank you Sir

[@trinovantian1]

Nice honest review Brian. Cheers mate !

[@SurvivalOnPurpose]

trinovantian1 Thanks.

[@peerzeidler]

cool friend the Best Militär Sleep System ! cool

[@misteragb7558]

Exactly what I was lookig for!! Thanks for sharing Brian!!

[@SurvivalOnPurpose]

It works great.

[@jeffhardie4287]

I hope fright train in all wether! I'm not knocking your video, I bought the same military system bag I'm not please with it... it's comes unsnap when tasing around in it and traps cold spot in-between the layers ,not something you want to deal with in sub zero weather..I have been using the old school Millarty OD green extreme for many years it's much more durable it's worth the weight to carry and a decent tarp to roll up in best of luck with your new bag?

[@danielk9475]

Sit on the compression sack while tightening it down. Makes it a lot easier.

[@SurvivalOnPurpose]

Daniel Kean Yep, that's what I figured out. It's still a job though.

[@L2FlyMN]

If you want to really compress the compression sack, try sitting on it, while you sinch it down.

[@andylundberg2932]

I have the older style one I picked up recently for about $80 bucks at an army surplus place online. I can't wait to get out there and test it out now that the temperature is starting to drop :-) Actually I got mine the same place that you got yours, mine was used but in the top quality category. I got a bunch of stuff from that site, they really have some good deals!

[@SurvivalOnPurpose]

Andy Lundberg I'm using mine for he first time this weekend in my Hennessey Hammock. I'll do a follow up in a few months after giving it a good shake down.

[@andylundberg2932]

Survival On Purpose I will be testing mine in my Warbonnet lol. We will have to compare notes.

[@SurvivalOnPurpose]

That will be interesting. I slept in my hammock last night with the black bag at about 60F. It was actually a little too warm but I just unzipped it.

[@nobodyshero2857]

Thanks for taking the time to make the vid, what is your opinion on someone that is 6'2" 240lbs would they fit?

[@SurvivalOnPurpose]

+Nonya Business I think so, but I can't remember the specs as far as size goes. I'm about 5'8" and around 170lbs and I have plenty of room. I used just the black bag last weekend in my hammock and was toasty.

[@christijarrett]

You still use your sleeping bag got mine in 2012 still looks and works as good as the day I bought it just a follow question they also have a camo bag also witch I have one for mine

[@SurvivalOnPurpose]

I used it last month in fact

[@slang1968]

Great info! Would an Escape Bivvy be necessary in addition with this particular system or is the patrol bag basically the same thing??

[@SurvivalOnPurpose]

+ROLLIN THUNDER That is what the outer camo Goretex bivy is for

[@slang1968]

+Survival On Purpose Yea that's what I thought but I'm hearing tons of folk suggesting adding the SOL Escape Bivvy along with this system. Thanks!

[@godSPARDA1995]

Can you roll the green patrol sleeping bag without damaging the material??

[@SurvivalOnPurpose]

I don’t see why not

[@thomasnugent7602]

Very good. Thank you very much

Hey Bryan im in the bartow county area here in georgia. I see you spend time in kennesaw, does that put you in cobb county?

[@SurvivalOnPurpose]

Gbaum515 Douglasville. Did you recognize that field in this video?

[@SurvivalOnPurpose]

That one was at Kennesaw Mountain at a field.

[@scottwallace5167]

Try getting in that setup in a downpour in the field. That said i will never look at rei systems again same thing 10x the cost. Good video. Just bring a plastic tarp with you if you anticipate rain. other than that it aint your grandmother's surplus.

[@klownmittenz8715]

Hello. Coul you have put the mattress inside the bag as well? Saw open to line the stuff bag and put in sleep system inside it? Thanks.

[@SurvivalOnPurpose]

I doubt it

[@klownmittenz8715]

Bummer. I like keeping things together and not having a lot of stuff tied all over my pack. Thanks for the response

[@1themanfromvan]

My question is if you can put only various parts of the entire system in the compression bag and still have it cinch down properly. For instance, if I know I am going camping in 20 degree low temps can I take only the black bag to reduce weight in a backpack? Or do I have to use a separate compression bag that is not part of the system? Thanks.

[@SurvivalOnPurpose]

+David Schmude I think it would cinch OK. If not, use some paracord. No need to buy another sack.

[@corazzinatanner498]

Newer models come with two compression sacks. One for the full system and smaller that will fit the bivy and the patrol sack.

[@johnboy7417]

Couldn’t find these for cheap online anywhere, me and my girlfriend went half on one for about 300. A little high but we love the outdoors so don’t care much about the price on quality gear

[@bustercrabbe8447]

The black intermediate cold weather bag is rated to 10 degrees above zero Fahrenheit. Not a winter bag. The complete system is a Fall sleeping system and not Winter. With the proper clothing?

[@SurvivalOnPurpose]

Where do you live? Siberia? Everything I can find says the system together is rated down to 30 below zero, which may be with proper clothing. Either way, it’s a winter bag for Georgia.

[@bustercrabbe8447]

@@SurvivalOnPurpose No, I'm from Boston and I've winter camped throughout New England for decades. Forty below zero F with the 'proper' clothing' is misleading. If you wear an arctic parka, pants, and mouse boots rated for fifty below zero F then you can claim an onion sack is rated for winter with the proper clothing. The military MSS is only an intermediate cold bag (10 °F) and that is definitely Fall weather. For sleet/hail/freezing rain/swirling snow found in a gale or nor'easter the MSS is Perfect, and is my preferred bag for September, October, November, and early December weather.

[@SurvivalOnPurpose]

I have heard it gets pretty cold in New England. The manufacturer’s website (Tennier Induatries) is pretty vague: “The MSS is designed to provide comfort in temperatures ranging from 50°F to -50°F when wearing various layers of extreme cold weather clothing.” All I know is it is a pretty rugged, fairly heavy, very versatile and reasonably warm set up.

[@Wingman115]

👍 Good stuff brother I need to get one.

[@SurvivalOnPurpose]

I'll let you know how it works after it gets cold.

[@danielcharbonneau222]

Now that you have had your MSS for a few years now how would you rate the bag. What was the coldest temp. that you slept in. I'm from Northern Ontario were the temps drop to below -30C. In you opinion will this bag keep me warm in that low temp.

[@SurvivalOnPurpose]

coldest I have slept in was about 25 F, with the entire system and no tent, just the bivy and green pad. It was warm enough for that

[@sebastiansilvar4518]

do we always have to use the woodland cover for any bag? or can we sleep with one of the bags by itself?

[@SurvivalOnPurpose]

You can use it however you want. I have only used the Bivy Cover one time. I usually just use one of the bags.

[@FASTONE1000]

Great video and awesome details.

[@SurvivalOnPurpose]

Thanks. I appreciate it.

[@johnnysal5635]

so for extreme cold weather, do I use Only the black cold weather bag, or do i use it with the other two layers?

[@SurvivalOnPurpose]

The colder it is the more layers you use

[@MartyBecker]

Can the bivy be used on its own for warm weather? If not, do you have a recommendation for a warm weather bag for use in a tent?

[@SurvivalOnPurpose]

+beckerm13 The green bag is pretty comfortable in warmer weather. If it's too warm for that do you really need a bag? if so, a cheap fleece one will work fine

[@MartyBecker]

+Survival On Purpose Thanks for the quick response!

[@morganblackheart9468]

It's a great system! However, my one complaint is that I don't feel like it'd be as homey feeling as a tent in rainy/stormy weather. It'd be a bit awkward laying down all day in it trying to escape bad weather, and the solution for that would be to bring a tarp to put over it! But again, other than that, it'd be a great system. As far as weight goes, obviously there's much lighter options but yes it's way warmer than any civilian system. As far as the weight goes, obviously no one says they wish they had more weight in their ruck, but I do train and condition myself to be able to carry heavy load outs. 10 extra pounds is pretty much nothing for me for a reasonable distance. Plus our soldiers hike for up to 12 miles with 80-100 extra pounds of gear, if they can do it we can too. Depending on physical health that is. Some people do unfortunately have disabilities. But if you're already healthy, I do definitely recommend conditioning your body. You'll be amazed at how much better you feel mentally and physically. Also don't be fooled by the weight, most sleeping bags are 3-5 pounds anyway. I have a 30° bag that weighs five pounds. Pair that with a heavy tarp and an inflatable mat like my single person intex mat with a pump, you're looking at around 10 pounds anyway. Plus most people add things in it that ends up adding the same amount anyway. My edc alone weights 5 pounds and my get home bag weighs around 20. So yeah. Just saying don't let the weight scare you.

[@SurvivalOnPurpose]

I have only slept out using this system with the bivy as the only shelter once. But I have used the bag(s) many times in my Hennessey Hammock. I just consider the bivy a bonus piece.
