[@williamhahn3749]

I use your packing strategies to pack my Ruck for the Army. While we do have to carry way more weight, cutting down on necessities and just organizing my Ruck has helped a ton to be travel ready faster and confident in my gear.

[@LZ-un7ky]

Thank you for your service!

[@Coreycry]

this is a "how to" - so much more information than just packing, many tricks can be applied to other packs.

[@longstrider461]

Yep, I totally agree!!! I took a lot of notes. It's going to very useful for an upcoming trip, if we can travel again :-/

Just packed my Kakwa 55L BP for my AT hike starting in 3 days. Barely had enough room. This is right on time. Darwin will never read comments on a three year old post. Just want to say, “Thanks, Darwin”, from East Tennessee.

[@Canadaman4403]

I’ve been labouring whether to go for the Kakwa 40 or 55 myself. My thinking was better to have More space and then just roll up the top no?…..?

[@arguchik]

This video was SO helpful. During the COVID "stay home" order, I have been daydreaming so much about hiking and travel.

[@GorgoScrobo]

I completely agree on the backup rain protection for clothes and sleeping bag/quilt. You’re one of the few folks who mentions the potential for packing up damp gear ON THE TRAIL. Thx for sharing your techniques, glad it works well for you.

[@elvismikel2271]

Keeping sleep clothes in the foot box of the bag/quilt and the gloves with the insulated jacket make so much sense that I can't believe I didn't think about it!

[@leleprtk]

Makes so much sense! I’m only gonna keep my sleeping clothes inside the sleeping bag quilt from now on

[@solitaryrefinement6787]

That's EXACTLY how I pack my loadouts; Horizontally. Besides it being more convenient and leaving some space on the sides for me to insert odd objects into filling in voids, the loadout is also more balanced because the weight of each item is distributed evenly across the breadth of the pack instead of being all on one side or the other. Unless two similarly sized stuff sacks are identical in weight, one will always be heavier than the other leaning the balance of the pack in that direction if they are inserted vertically.

[@tamarmolerick3814]

Great vid. I prefer to keep raing ear, hat and gloves in my big outside pocket, that way if it starts raining you don't need to open your pack at all.

[@00xanawolf00]

Thank you Darwin for this video. I’m limited to 20 pounds for the rest of my life due to a catastrophic back injury and subsequent surgeries, and I used your gear and packing vid to help assemble an emergency “get home/bug out” kit.

[@JeDindk]

I'm going on my first hike later this month and your video was a great help to me. I am both a little bit puzzled and a little bit confused, when I think about what I shall bring and how to pack everything ..... I think the most important message from your video is, that you can let your self be inspired by others, but in the end you have to figure out yourself and you always have to re-evaluate your needs. You can start with a 65-liters backpack and end up with just 35. You can start with a butt-pad, get rid of the butt-pad and finally bring the butt-pad back again. So what I have learned from this video is, that it doesn't have to be perfect the first time. 😀

[@leftycut1]

Anyone who doesn't know or recognise you must think your on a day hike !! It is amazing how small your pack is. Love this stuff !!!!

[@jjjj7302]

Now I want to know what you pack for 4 days of food :)

[@GuilhermeBianeck]

I just packed my bag almost identical to your way, holy smokes what a difference! The way it was loaded and is loaded now actually feels soooooo much lighter and while I always look like a kid over an oversized bag, it compressed down so much. Thanks for this awesome video!

[@westcoastislander6699]

Recently "downsized" from a 60L pack to a 50L pack and have made an extra effort to lighten up my gear this year (getting old sucks but you don't have to comply!). Have been trying to figure out a more efficient way to pack the gear in the "smaller" (as opposed to 35L!) volume and this vid gave me a lot of light bulb moments. Thanks for posting this!

[@lorens7837]

I think I've watched this video 5 or 6 times now and I have learned a ton but the most immediately helpful idea is NOT to compress and fold and stuff my sleeping pad into a tiny little stuff sack but instead to FOLD it and put it against my back for additional padding. What an AMAZING idea! (Why didn't I think of that myself?) I like the additional comfort on my back and my pad (Thermarest Trail Scout shortie) loves not being compressed to death. Thanks, Darwin!

[@GustoStCool]

Going down to the 35L is really gonna put a dent in how much delicious Bud Light you can carry.

Putting your extra clothes inside your sleeping bag is genius! Also folding the sleeping pad another genius idea (never even considered it). Thanks.

[@hokuspokus8947]

Ahoy! Another great tip for keeping your camera dry while attached on your shoulder strap is to use an inexpensive shower cap. The elastic banding keeps it tight around form of the camera body. Happy trails mate!

[@novakillbones2140]

You guys in North America have it so easy. If I was going out bush for 4 days, I'd want to carry a minimum of 8 litres of water. There is also no way I could fit 4 days worth of food in that bag of yours. And there is absolutely no way I could go bush with a frameless pack, I need to have airflow between my pack and my back. I also prefer to pack vertically so that I only have to get out the thing I need, I never have to pull everything out of my pack to get what's in the bottom. On the upside, it doesn't get cold enough in Australia that I need to carry as much warm stuff as you guys. Still, a down jacket isn't quite as heavy as a day's worth of canned food.

[@dalechristopher3917]

folding the sleeping pad flat. genius! ima start doing that!

[@lois6705]

I followed your packing advice for my 50-mile section hike of the Vermont Long Trail and it worked really well. I got rid of an extra bag for clothes and everything was really easy to find. Thank you for sharing.

[@VirtualTurtleGames]

I'm literally preparing for my first multi-day hike when this is all over, and was wondering how to pack my 40L pack in the best way. This is such a great coincidence! Thanks for the vid budd!

[@JimYeats]

No criticism, but I find it funny that you have this completely organized pack that is well though out, well balanced, lightweight, and then right at the end your most ungainly weight item gets thrown onto your shoulder strap. Love it, just shows you that we like what we like, and if taking awesome photos makes you happy, then it needs to come along.

[@WILDONTHETRAIL]

Very helpful in downsizing and packing my warmer weather gear. I think I’ll move my rain jacket into the top of my pack since I’m toting an umbrella. “Darwin Off The Trail”, made me chuckle, yet, hope for better days ahead.

[@JohnFisk-OHS-78]

Totally agree about the umbrella - supremely posh bit of kit and not that extravagant in terms of weight. I've farmed in -30 F weather in the teeth of white outs and gale force winds. I don't mind the cold. But, I HATE getting wet... cheers!

[@marktapp5408]

Excellent suggestions and great advice. One alternate suggestion might be to keep a second pair of dry socks in a baggie in the mesh pocket instead of buried in the bottom of the pack. Thank you for sharing your knowledge!

[@FrozensAdventures]

OK yea I do pack like you, was a bit confused on the QA. I think I'll try the extra/night clothes in the quilt idea. Thanks man, great video!

Awesome video. I just purchased an Osprey Kestrel 38. This reassures me that I will be able to pack a tent and everything else for an overnighter, possibly a multi-day trek. I have read a lot of comments and reviews all over the internet with people saying 38L is barely enough to go out overnight, and to basically forget about bringing a tent. Others have stated that a 38L is more than substantial for this.

[@philsmith2444]

I’ve done a few weekenders with an Osprey Manta 36 AG, which as a day hiking pack isn’t really ideal for backpacking due to pocket configuration. I replaced that with a Kestrel 38, but didn’t really like the fixed lid (the pack was just plain superb in every other way, though) so I went to a Granite Gear Crown2 38 which is just about perfect for me.

[@grampakilt]

In my considerable years of viewing UL hiking videos, never have I learned such a logical way to gear pack. You have brought just a bit more order to my scattered mind. IMO you have achieved your PhD with this! GK

[@clinclin1240]

In 2026 you can just set up a waypoint and teleport all your gear to camp.

[@philsmith2444]

I recently switched from a framed Osprey Kestrel 38 to a frameless Granite Gear Crown2 38 (often with the lid removed so probably 33-34l), and it’s interesting how small modifications to your packing change the way weight is transferred to your hips. The GG isn’t a true frameless pack since it has a back pad and frame sheet, but there’s no wire perimeter frame. But I also figured out through trial & error to move the heaviest stuff up a little bit (I like it between 1/2-2/3 of the way up and right against my back.) This even makes 2 1l bottles in the side pockets comfortable. I’m not a thru/section hiker due to my job and having bad knees, and even though I don’t buy all the way into the UL philosophy I watch, learn from, and shamelessly steal anything that looks useful from 8-10 hiking/backpacking channels. It’s definitely made my 1-2 night trips better. Eventually (after TKR) I’d like to do the Long Trail in one shot if I can take a kind of sabbatical from work. Plus I’m barely an hour from the 100 Mile Wilderness, which looks like a real challenge. Carrying 10 days worth of food in my Crown2 38 is probably not feasible, though.

Thanks so much for this video. I watched this video a couple of times and then pulled out all of my gear and tried your system. Once I was finished I had a pile of stuff sacks left on the floor had a ton of space in my backpack. I’ve watched several “how I pack” videos from other KZbinrs and yours definitely made the most sense to me. So thank you for sharing this and helping me be more efficient with a lighter pack. 😊

Hi Darwin, can you give your DCF bag size for quilt and food please? Thanks from France!

[@shramj]

One thing that really helped me fully utilize my pack space is removing almost everything from their stuff sacks. I pack most of my items in a pack liner and it pretty much fills in all the dead space in the pack. I keep my food bag, accessory bag, and tent outside the pack liner on the top part of the pack so if it rains, I can still setup my tent and then place everything else inside the tent keeping everything else dry.

[@northstarhiker]

Nicely done. My pack is haunting me, sitting in the corner of my room all packed and no where to go, but I keep glaring at it wondering how I can get it smaller. I really like the folding the ground pad idea. Will have to incorporate that for sure. Thanks for the tips as always and be safe. Happy trails, soon.

[@willpotter8343]

Best tip was the folding of the sleeping mat for storage, instead of rolling. Thank you

[@GaerHampton]

Great video! I never thought of folding my X-therm pad as opposed to rolling it. I'm still amazed at how small backpacking kits/packs have gotten over the years. I used to marvel at how small other backpackers' pack where compared to my 90 liter monster! It took me quite a while to catch on to packing less, and lighter. Now I'm at the very least a "lightweight" bacpacker. I actually have been using an external frame pack for the past year.....mostly for nostalgic reasons. Now that my packs are so much lighter, I actually enjoy the hiking part of backpacking! Here before too long I think that I'm going to downsize even further to a smaller, ultralight-type pack. It's amazing how little you actually need to stay warm and protected while out in the wilderness. I wish that I had figured that out 20-something years ago!

[@jlkartvideos9887]

Total weight in the bag is depending very much how cold and rainy weather you have to be prepared and how much warm clothes, food and water you have to carry. In Finland's cold weather (not in the winter) 8-9 kg (without food) is already very light gear and in one week hike you have to have about 5 kg food.

Good advice. I went from a 65 to a 40 pack after realizing I was carrying what I didn’t need. Focusing more on the journey than the gear.

[@EspenFrafalne]

Bikepacking is more ideal for packing a little extra. 10-12kg on my MTB is barely noticeable on a flat road. Great alternative for people who dont have $1000-1500 to spend on ultralight gear, or who want to bring their laptop or other luxury items, or for people who just want to cover more distance in a day :P

Fanny packs are great! I got one with a bottle holder, which i think is very practical. I recently got a 33liter "Arcteryx FL 45" backpack with a roll top that can be rolled out and expanded up to 45 liter if i need to. The backpack is from pretty sturdy material, has a back plate to stiffen it up, and is completely waterproof - but it still only weighs 650g/1,43pound. I can fit all my regular gear, a 1 liter bottle, and a LITTLE food in the 33 liter "configuration"...
