    Comfortable, Stays Dry

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: XL
    • Height: 6'2"
    • Weight: 230lbs

    These have a comfortable fit, and stay in place with lots of movement. They do a great job at keeping dry when conditions cause you to sweat. Only negative is the price, although they do seem to be worth the premium.

    compression +Arc'teryx = great

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: L
    • Height: 6'4"
    • Weight: 190lbs

    these are well made, give good compression, and are a great base layer underwear for skiing or to wear everyday

    Hard to beat Arcteryx!

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Medium
    • Height: 6'0"
    • Weight: 175lbs

    When you are buying Arcteryx, you are buying quality. Bought these for running/hiking and couldnt be happier. They dont ride up, they wick moisture, and fit great. Going to order more

    Used all over Costa Rica - awesome!

    • Familiarity: I've used it several times
    • Fit: True to size
    • Height: 6'0"
    • Weight: 230lbs

    These are a fantastic wear for all around activity. I wore these several of the days in Costa Rica and they were awesome. Easy to wash in the sink and dried fast. annoying to not have the opening at the front, but not a deal breaker. didn't ride up and they are keeping together well.

    Remarkable

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Medium
    • Height: 6'2"
    • Weight: 180lbs

    Slightly tighter than the old version but remains to be perfect fit. It stays in shape throughout the day irrespective of intense activities with heavy sweat, or sitting behind desk. Perfect balance between elasticity and holding power to stay in shape. Folds into tiny volume and dries in no time - ideal for travel.

    Lightweight comfort

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Small
    • Height: 5'8"
    • Weight: 140lbs

    This is the best underwear I've ever owned, I just wish it wasn't so expensive (hence only 4 stars). I wear mine hiking and have found it doesn't restrict movement, wicks moisture, dries quickly and doesn't readily smell.

    If they were a bit cheaper then I'd buy enough pairs to always wear them.

    No room up front!

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: Medium
    • Height: 6'0"
    • Weight: 180lbs

    Hate to give a one star, but these are unusable for me. I am not going to return used underwear so I am out way too much money on these things. Not even close to enough room up front, anyone who needs a little room will know what I mean. Would recommend people check out the "MyPakage" brand underwear sold on backcountry, save yourself the $45.

    good choice

      面料就是phase SL,跟鸟家跑步T恤 motus的面料一毛一样,所以皮肤的触感和舒适度没话说。质感轻薄,适合夏天运动时穿。
      价格是75折,还行吧,折合人民币225元。我估计,再等等,会有7折的价格放出来。
      我体重80公斤,腰围95公分,选了L码。基本合身,就是感觉腰位低了点儿,裤脚略松。计划再入手一条M码的,做个对比。

      If you can afford them, get them.

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Medium
      • Height: 5'8"
      • Weight: 160lbs

      If I could afford to only wear these, I would. They are super comfortable and after several washes, show no signs of wear. Are they worth the $$? I dunno. They sure are great though.

      Can recommend

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: True to size
      • Size Bought: M
      • Height: 5'10"
      • Weight: 190lbs

      This is a low rise underwear. Very comfortable. Spend 3 days in the mountains.

      Finally

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: Medium
      • Height: 6'0"
      • Weight: 177lbs

      Tight enough to eliminate chaffing but not to squeeze the fun out of your activities. Expensive but worth it, I highly recommend.

      Good fit

      • Fit: True to size
      • Size Bought: Medium
      • Weight: 162lbs

      It's nice and good fit, didn't try it for a hike yet :)
      The quality looks but, not sure if it can last long or not... a bit expensive if it didn't last long.

      Can get better for the price.

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      The quality seems to be good. I've had these for over a year and they are holding up fine. However, they I still get chaffed wearing these sometimes. Even on shorter hikes. I have boxer briefs from other companies that prevent chaffing a lot more and cost less. Also there is no fly hole. Not sure why this bothers me because I don't use it but it does. For everyday these are fine but for longer trips in the backcountry I would look for something else and save a few bucks.

      You can't put a price on chafe-free

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      Are these expensive? Yup. Do they lack a flyhole? Yup. Do they chafe? Nope. And that's the most important thing when you're out on the trail. Arc'Teryx has made these ultralight, yet surprisingly durable. The seams are well-stitched, and well-placed. The fabric is smooth on the inside and out to prevent friction. As an added feature, these breathe better and wick moisture better than other poly-weaves; phasic fabric doesn't just feel nice: it's superior. Add in silver-ions to fight stank and funk and you have some great skivvies here. I've used my first pair consistently in rotation for 6 months, and have decided they're great enough to purchase a second pair.



      For fit: I'm 5'9", 160 lbs with a 30-32" waist and slim legs. Size small fits comfortably.

      $45 and no fly hole!?

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      These are by far the nicest pair of boxers I have ever owned. I wore them 4 days in a row on the Northville-Placid Trail and they held up beautifully. They're soft, durable, quick drying, and comfortable.



      With all of that being said, I do have 2 main complaints. First, the legs tend to ride up without fail. Luckily, they are so comfortable that it really doesn't bother me that much. Second, they don't have a fly hole! It may not bother some people, but if I am going to pay $45 for a pair of underwear, I expect the most basic convenience that even the $5 underwear from WalMart has. Even with all of that complaining, I will most likely be buying more pairs soon.



      Best Boxers Ever!

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      I bought a couple pairs of these for my thru hike, and I have been very impressed with their performance! I could wear these things for days without having the chaffing problems I have with regular boxers. They are expensive, but when you're on day 3 of wearing them hiking 18 miles a day with a heavy pack through Virginia in the summer, you will be glad you spent the extra money!

      Very Nice

      • Familiarity: I've used it several times
      • Fit: True to size

      These underwear are extremely comfortable, they don't chafe, don't smell and wick sweat very fast. Great for hiking and outdoor activities. One or two pair should be plenty for a trip. I'd definitely buy again.

      Pretty nice

        I have had these for about a year. I have 2 pair and wear them as often as I can, especially in the summer. The material is like no other. It is so light and soft. I can literally see my hand through the material it is so thin, but yet they seem very durable. The material looks as good as the day I bought them. Moisture wicking is fantastic, and it is the only underwear I have tried that keeps me dry even on those hot summer days. I have a pair of ExOfficio, but I haven't had the chance to test these out in the same conditions, so they may be as good. The ExOfficio material is definitely thicker and not as comfortable probably due to the texture. I also like the thinner waist band on these, and I haven't had any issues with it rolling or folding over. Although the waist band doesn't feel nearly as nice as the rest of the material. Last but not least, they cradle the goods very well, and everything feels nice and supportive without being squished. I can't imagine a better fit in this regard.



        My only complaints are the price, and the material tends to loosen around the leg until they are washed again. I am 5'10", 160lbs with a 32" waist, and I have the medium. I wish they were a little snugger around the leg even straight out of the washer. Arc'teryx calls it a boxer, but the fit is really somewhere inbetween a boxer and a boxer-brief for me. A person would need some seriously large quads to fill these out. Compared to the ExOfficio boxer-brief, I like the fit in the butt and crotch better on the Arc'teryx, but the ExOfficio definitely fit nicer in the legs if you prefer the legs to have a snug fit.



        As good as these are, it's really hard to justify paying $45 for a pair of underwear, especially if they are not perfect. I would give these 5/5 if Arc'teryx would fix the leg stretch issue and drop the price $10.
