[@TheLifeOnHigh]

The MW briefs are so comfortable. The material is like the most premium feeling underwear I’ve ever worn. I used to think Calvin Klein held the title for best materials but as a grown azz man I feel the Mack Weldon are more grown up.

[@AkimboLizard]

When spring was approaching I decided to bite the bullet on Mack Weldon, when eagerly awaiting my order, I searched them on youtube for review where I found your videos, from there I was introduced to men's fashion youtube and it's really been eye opening and taught me a lot, all contributing to fantastic changes in my life so thank you for your coverage of Mack Weldon. I love my Mack Weldon clothes, working out in full AIRKNIT will change your life, and their shirts and shorts are great. I wish their no-show socks were better, they frequently fall off my heel and my light gray pair are already visible distressed in a few areas but for whatever reason, the dark blue pair that came with it is in much better condition with close to equal wear so I don't know what that's about

[@tigergreg8]

I LOVE the AIRKNITx. I have at least 6 of the boxer and the t-shirts, I also have the sock for every day. I bought 2 Silvers and I think a couple 18 hr. Mack Weldon can thank you for the sale because I bought them because of your review a while back. Honestly, once you wear the AIRKNITx, you won't want anything else.

[@The_Kavalier]

Couldn’t agree more! Same with Bonobos model comment 😛

[@JRCxyz]

tigergreg8 What are your thoughts one year later? Do you still prefer the AIRKNITx over the other models, particularly the Silver? What about other brands? Is there a favorite?

[@rasperryguy1197]

How do the tshirts hold up and in which conditions?

[@tigergreg8]

@@rasperryguy1197 I’ve been wearing them almost every day, with the exception of weekends, and the t-shirts have held up very well. I work in a Hosp with lots of moving around , and with all 5 being washed every week, they still look good. I’ve had them for quite some time now, and realize you get what you pay for in clothing, or most things really. I would buy them again, but since this purchase I’ve done across a company called Rhône and their clothing line is incredibly comfortable. I bought a pullover and pants, Commuter Pants is the name, and I’ve never had pants feels that comfortable. I can only imagine what they could do with underwear. I may just purchase upper and lower to try them soon. Hope this helps.

[@rasperryguy1197]

@@tigergreg8 definetly helps. Thank you for sharing.

[@BEASTPRINCE09]

This video was very helpful for someone who has been wanting to buy from them for years! I do with it had some modeling shots though, and I find those very helpful. It makes things more accessible when you can see them on more regular bodies and not the super muscled/model ones.

Btw, I just got the Bonobos catalog, and I think you should be one of the models for the catalog. You're such a fan, and honestly, your build is perfect for the catalog. I may write to them and ask, and see what they think.

[@The_Kavalier]

Let me know what they say! They never answer me 🙃

[@mikeacord5329]

I'm another subscriber who discovered Mack Weldon based on your recommendation. I wore the sweats all winter. Love them. Have a pair of the shorts also. I have a couple of pairs of the Silvers and really like them. Like you, the AIRKNITx is my favorite. Best underwear I've ever worn. The quality is exceptional.

[@GRDowntown2020]

I bought them based on your videos. Very pleased. My AirKnitX pairs arrived today and I love them!

[@The_Kavalier]

Great to hear George! My absolute favorite 😊

[@EnthusiasticGoat]

As someone who owns the same sock and color I can attest to the quality. The underwear is so good you wont go back. Also the reward program is stupid good and its automatic with your account so nothing to do extra then just buy. I used to buy meundies and they are good but the underwear pilled like crazy but it still hold ups well. Great video as always man!

[@The_Kavalier]

Thank you Sunshine great to hear!

[@charlesmizelle6482]

Buying clothes online from web based companies has been very hit and miss for me (more misses than hits I’m afraid). 5 star experience buying from them. Seamless customer experience for me. The AIRKNITx really are the best I’ve ever worn.

[@The_Kavalier]

Love to hear that Charles!

[@rmb10]

Mack Weldon and Saxx are my favorites. My preference is the 18 hour jersey. Love your videos!

[@rmb10]

Forgot to mention that I have the sweatpants---they are so soft and comfortable, in typical Mack Weldon fashion. You should get a pair, I think you'd love them.

[@JaimeGonzalez-wx1gw]

You prefer the 18 hour over the Airknitx?

[@rmb10]

I prefer the 18 hour

[@JaimeGonzalez-wx1gw]

rmb10 Because of you I ordered the 18 hour and I like them just as much as my Airknitx.....thanks a lot!

[@rmb10]

I'm going to order some of the silver technology to try.

[@nathenroe-sv5yt]

Mack Weldon 18hour jersey or Saxx for every day wear? Wish the AirKnitx had a fly based on your recommendation.

[@zanyu]

Do you prefer these over pouch underwear? I have actually bought a whole weeks worth from Sheath underwear due to the dual pouch system was just a huge game changer for me. It literally removes any chaffing and just extremely comfortable. I have no idea if I can go back to underwear without a dual pouch system.

[@The_Kavalier]

Yes I like the fabric of the AirKnit x more than functionality of the pouch but I like having a pouch in my rotation for occasional use. Have some more pouch coming!

[@kirkobang3371]

Me too.. I buy Alpha box, B3nth, Sepratec and Shinesty. all my favorites

[@pablocoppola5397]

Great review! I'm a fan of Lululemon but I'll definitely give the AirKnit a shot since we need it out here in AZ!

[@vinceyarborough1303]

Really liked the AirKnitX trunks, thanks for your reviews, nice presentations.

[@deeplypresent]

Here I am a year after restocking my underwear drawer with uniqlo briefs wishing I had listened to your “fewer better things” philosophy back then. Just ordered a pair of each and hoping these will last longer. By the way, what are your favorite performance brands these days?

[@twoscoops2]

I only have silver boxer briefs, been wearing them since they came out. Every time they get a new color I pick it up. I'll have to try the others one of these days. I was briefs back in the day, but like boxer briefs or trunks best.

[@springsteen4ever]

Would you prefer Mack Weldon over Calvin Klein?

[@marvelboy74]

Ordering some trunks now!

[@b5006-v3h]

I am definitely a briefs wearer. Would definitely be interested in a performance brief reviews/collection since you mention you’ve been leaning towards that. Don’t think there are any videos out on KZbin discussing it.

[@The_Kavalier]

performance - Under Armour, Rhone, etc??

[@b5006-v3h]

Any really. Everyday wear even. Would like to know options for sure.

[@SalluhMown]

Still waiting on that Mack Weldon sock review. But I got really impatient and jumped the gun and bought a ton of them anyway 😅

[@lukechaves]

Hey Jon, I just picked up some airknits trunks and love them. What other products from Mack Weldon would you recommend. I'm especially interested in their shorts and shirt offerings?

[@The_Kavalier]

I have an airknitx tee that is my go-to. I have their crew and vesper polo which I really like too. Seems like you can’t go wrong!

[@drlatham22]

I have Tommy John and Saxx; maybe I need to buy/try Mack Weldon.

[@sukhdarshansinghsehmbi8607]

A beautiful video& have to say a great collection of the boxer shorts you have, you've called them trunks but a great collection you've built, I've bought loads& they've started to deteriorate over time

[@foolpersona_]

notification squad? haha. Just tried Mack Weldon Silver line of boxer briefs (literally just got them yesterday) and I am impressed. They are expensive though, but yet to see whether they can hold up and if they are worth it.

[@The_Kavalier]

Cool! Bet you’ll have them for years with proper care!

[@MrPontiac005]

I know this video was awhile ago but would you recommend the airknit for everyday use as well as working out in?

[@HAW4868]

I had an issue where I had 10 pair of Medium, all 18-hr, and 2 of them fit like an extra small. MW refunded those and send replacements, but was wondering if you ever came across that issue

[@anthony5570]

?

[@The_Kavalier]

True to size! I am basically a medium in everything I wear now so yes.

[@clarkewright888]

I have found that the sizing in the Mack Weldon chart is not accurate. My waist is size 32" and the medium are too small for me, especially in the pouch. I now own 15 pairs of Mack Weldon briefs and 2 pairs or trunks and even though the size chart says Medium is 31" - 34″, I purchased the rest as size large and they are just big enough. The waist on the medium is too small for me at 32" and the pouch is really tight. The waist on the large-sized briefs is comfortable and there is just enough room in the pouch. But for me, it would be better if they made the large-sized waist with an extra large sized pouch. So I wouldn't recommend buying them as small, medium, large, etc, but choose your waist size and then go up a size. If you need more room in the pouch, I would recommend buying one pair in one size and giving them a try first. But overall they are very comfortable underwear and very well made. The colour choices are also super cool.

[@ValkryNL]

how does the uniqlo hold up to these mack weldons , and say meundies?

[@nylenz2054]

Got a question for you Kavalier and the community. What type of underwear you wear? When I was in high school, I was wearing loose boxers, but it was not comfortable in general since it was not securing the package. Getting to the 18-23s , I was wearing boxer brief , felt much more confortable. But since some time I am trying briefs as underwear but are there some good brief underwear brand? I bought some lowbrand just for try but I don't find them comfortable after some hour during work time. Might try Mack Weldon tough. Thanks in advance.

[@TheRandomHighFive]

Nylenz I went from hanes boxer briefs to saxx 24/7 and their quest 2.0. Can't recommend saxx enough. Super comfortable.

[@The_Kavalier]

I’m mostly a briefs guy now but it took me a while to transition from boxers in high school. This would make a great dedicated video

[@nylenz2054]

TheRandomHighFive Thanks for the suggestion. I'l look into that brand for sure!

[@nylenz2054]

The Kavalier Thanks for the answer mate! It would be a good subject as for a video yeah.

[@cyclexy]

My personal favorite is JOHN SIEVERS sold at International Jock. They are about the same price point as Mack Weldon. They feel great and look great too!

[@Herreraluis106]

Does anyone know if there have been any changes to the Mack Weldon line or does this review still hold up?

[@howardkerr8174]

I would be interested in know the answer to that, as well. A few weeks ago pop up ads for Mack Wheldon appeared on my tablet....never heard of the brand before. I went to the website to get an idea as to what made them so...special. It appears, that unlike Jockey, Mack Wheldon puts mesh panels in their underwear where it isn't just decorative.

[@sukhdarshansinghsehmbi8607]

A great video once again 👍

[@chrism6904]

Sorry, I just smoked some weed (and im not sure if I missed it already) ... But I saw an Ad for these clothes on KZbin (Mack Weldon)... Are these supposed to be "high quality" clothes, such as Armani?

[@sukhdarshansinghsehmbi8607]

You'll notice the elastic will go quick on them, but will last you a couple of years or a lifetime depending on the fabric/quality

[@scottd.3382]

I really want to love Mack Weldon underwear. The design and materials are great, and the construction is high quality. Unfortunately, I have major issues with both leg and waistband rolling. The boxer briefs I own are older versions. I wonder if the newer versions would be better for me? Do you have any issues with leg and/or waistband rolling? For reference, I am about 5'8" and 140 pounds (after dinner).

[@The_Kavalier]

A little bit but that’s why I’ve mostly moved to the briefs. AirKnitX briefs are the only pair I need

[@scottd.3382]

@@The_Kavalier I just wish they'd add a fly to the AirknitX.

[@Tom-xb9rj]

I'm a huge fan of the channel, although this is my first time commenting. There's something I wanted to share/bring up and also see if any other guys have had a similar experience or problem, but please delete if not allowed. I'm going to try to be tactful but also I hope that we can speak freely about our bodies as men to some extent. I know that Jon is a fan of Mack Weldon, so when I was looking for some new underwear I bought some in the trunk because I wanted trunk underwear with a fly and also liked the idea of the jersey fabric, but I had a problem that I haven't been able to get around and that is that the crotch area is truthfully just not big enough. I feel like when you look at the Mack Weldon trunks laid out, the front looks just flat across with the fly obviously in the middle. From a purely statistical perspective looking at the general male population, because of course this is intended only to be a discussion and not some weird flex or value judgment or anything, you could say that I have reproductive organs that would be considered, I guess, on the large side of the spectrum. When I would wear the Mack Weldon trunks, I found that on me they would compress that area to the point of pain (think the feeling of being kicked in the groin halfway through the day). The jersey is stretchy, but it's like there is just not enough of it there. I went to the Tommy John second skin trunks, which if you look at them the crotch is actually built with some extra space, not a separate pouch, but you could say that there is sort of a pouch-like structure there and that solved my problem. I am not a shill for Tommy John or anything, and I know that Jon has said that they don't seem to hold up well after multiple washes which I haven't had them long enough to see, but that was a problem that I had with Mack Weldon in general just in the way they are built. Like I said, I sort of wonder if anyone else has had a similar issue?

[@justintullock9371]

Im a big Tommy John fan. What can you say that you didn’t say here that could sway me away?

[@streetriderlee4993]

[@The_Kavalier]

[@forget3817]

Have you considered the traditional brands? At $20+ a pair, Mack Weldon is very expensive and I've found no real difference among polyesters. My feeling is that Fruit of the Loom's "Breathable Micro-Mesh" briefs or trunks would compare favorably to the MWs, and provide much, much greater value. (BTW, the silver thing needs to be proven. Remember, it is still surrounded by other materials that can retain odor and germs.)

[@davidailep5245]

Have you ever tried Duluth trading co underwear? They have some pretty good options also.

[@Rooxie973]

I was sold on Duluth from all the reviews. But stumbled across a few that said they aren't what they uses to be. That's why I'm here watching this video now, might go with these

[@JavierFlores-di7le]

[@kcopen]

I know this sounds insane but I hate the contrasting white waistbands on Mack Weldon. Do you know a quality brand like this that has a more uniform looking waistband like the Silver, but more of a daily wearer (and without a giant logo on it also, ugh)

Mostly a briefs guy and would like to see a future video focusing on briefs that you would recommend.

[@cyclexy]

So I had never heard of this brand before until I came across your channel. The only thing I don't understand about these undies are the price. I'm sure they feel great, fit great and wash well but they just don't look like they should cost what they cost. Typically underwear that is $24 or more is more stylish looking than these. No shade just my point of view. Always great reviews though.

[@The_Kavalier]

Material innovation not looks. Do you mean Rounderbum style? I keep thinking they might be worth a try

[@cyclexy]

Gotcha. I do not know this brand. Will look them up though.

[@cyclexy]

So I checked out Rounderbum. Talk about special needs underwear. They have padded and lifting undies. I doubt you need those. As far as style goes was thinking more like Marco Marco.

[@joshx413]

Honestly. I thought the price was Ludacris. I scoffed at the idea of paying more than $7 for a pair. Then I graced my tochus with the AirnitX and I will NEVER buy a cheap pair of underwear again!

Why in the world does Mack Weldon think it’s a good idea to have a 2 x 2 inch square decal on the outside of their underwear with the fabric content, washing instructions and international care symbols ?
