BodyFit 150-Ultralite Anatomica Brief

The Icebreaker BodyFit 150-Ultralite Anatomica Brief regulates body temperature and naturally resists odor for all-day comfort whether you're on the trail or off it. Flatlock seams reduce bulk when you have a lot of layers on cold days.

  • Merino wool stretch blend
  • Natural antimicrobial odor-resistance
  • Smooth flatlock seams
  • Closed contoured pouch

Small Pouch

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: medium

I really wanted to like this item, I live Icebreaker merino shirts, both long and short sleeve, but I couldn't wait to take these briefs off. Ordered 2, wore one around, and returned the other. The fit is small. I'm 5'9", 145 lbs. and not a porn star. The size medium wasn't comfortable. There are a bunch of better fitting briefs made by other outdoor companies that cost half as much and perform just as well.

Great underwear for active lifestyle

    These are great for skiing and hiking. They wick moisture well and don't get too stinky.

    Runs very small

    • Fit: Runs small
    • Size Bought: medium

    I bought the size medium and found it to be uncomfortably small. I have a 31 - 32 inch waist and wear a size medium in all briefs. I don't think that these are true to size. I have a size medium pair of the Icebreaker briefs that I purchased a few years ago that fit nicely.

    Brief runs small, supportive but...

    • Familiarity: I returned this product before using it
    • Fit: Runs small
    • Size Bought: Medium

    Bought these for active use, running, etc and because the Arcteryx briefs are no longer made. Tried them on but found them to be tight and confining around the sides. Fabric seemed nice, and support was adequate, I just felt comfort was lacking. Afraid I'd take them off and have red marks on my hips or something. Considered going up a size but I think that might sacrifice the support so I'll try another style.

    Very soft

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size

    If you like to be pampered even in the harshest of treks then scoop up a pair of these bad boys! They wick moister away from your skin to keep your precious cargo from chafing. Fit true to size.

    Great Product

      Bought a couple a while back to test out sizes and now just put in an order for a few more. I normally wear a medium and it fit a little tight but the large fit perfectly. I did notice the tighter pair started showing signs of wear a lot quicker than the larger pair, I know other people have alluded to them wearing quickly so don't know if fit might be the issue there. Besides that it's a great product, and a lot cheaper than some of the other brands.

      Briefs, but better

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

      Think about your standard briefs, then make them better in every way. Super soft, plenty of support without being constricting, and don't ride up when hiking. Also, tagless. No one needs tags anymore, let's be honest.

      Wool undergarments have changed the game for me, I will wear these in the backcountry for days at a time if necessary.

      I wear a 35 waist pant, and the Large is right on the money.

      If you're wondering about style differences, attached is a photo of the 4 styles, clockwise from top left, the brief, the boxer brief, the long boxer, and the relaxed boxer. The boxer brief and long boxer fit about the same in the thigh, the long boxer being about 1.5-2 inches longer.

      Briefs, but better

      Fantastic Support

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

      Being pretty sensitive to wool products, I've been super pleased to find that these boxer briefs don't itch at all, not even around the waist. I've worn them for a few hikes and bike rides, and they have performed really nicely. They stay supportive even after a full day of activity, and regulate temperature and moisture well. Really impressed with these.

      Fantastic Support

      Awesome comfort

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

      The comfort alone of these briefs make them worth it. I've put them through some serious use climbing and mountain biking in southern utah, and sitting in an office during the week. They've been used in both hot and cold conditions and have remained a go to piece of my equipment. I love that they hold their shape and remain comfortable through their use!

      I definitely recommend these to anyone looking for briefs that will last when you're putting them through adventures.

      Awesome comfort

      Au Naturale

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

      Natural fibers that are super soft and comfy. My husband loves these.

      No Fly Zone!

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: True to size
      • Size Bought: Large

      They keep everything in place, are cut well, and feel comfortable. Be warned that they don't have a fly, though. I prefer to go through the gate rather than hop the fence, so that's a bummer for me. Otherwise, they're great.

      Feels Great

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: True to size
      • Size Bought: medium

      I'm usually between sizes S & M and so it's always a toss-up when buying an unfamiliar brand. This is the first Icebreaker product I've used and I've found it very comfortable. I plan on using it for hiking and other outdoor activities, but I've mostly just worn it around the house. I don't feel any pinching, tugging, scratching, or the like. Some have commented on the leg holes being tight-- I have average thighs and I haven't had a problem with that. If you've got similar features, I think these would work great for you although I have as yet to test out the durability aspect.

      Super awesome briefs! Brief life though.

      • Size Bought: xl

      Ok, so these are pretty much a win. They're super comfortable, no ride up and they are wedgie free for the most part. They are moisture wicking so no swamp butt; and after 4 days in the backcountry sans shower.. your nethers are kept odor free by the awesomeness of the merino. The fit is good, the fabric feels supreme and the cut is great too. The only complaint is durrability. Ive had them for 4 months, used them moderately and the crotch has already torn out at the seam leaving a large hole in the taint area. So aside from the durability issue these are a win, but for the price I would look for something that would last a bit longer.

      Jury Still Out

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: True to size
      • Size Bought: Medium

      I normally wear a medium in briefs so I bought medium in the Icebreaker brief. Everything is fine except the leg openings are tight. I'm used to wearing ExOfficio Give-N-Go Sport Mesh brief and I much prefer the fit of the ExOfficio. Maybe as time goes on these will hopefully loosen up a touch.

      Very nice and easy to clean

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

      Okay, here is what I have found...The performance of these is just out right amazing you can beat them. They dry super fast if you need to give them a quick wash or if your like me and some time just want to jump in a ice cold river on a cold day. Just give them a quick wring and you are ready to go. The only reason I ma giving these a 4 star rating is the giant tag that came attached with the force of a thousand elephants. It is a huge pain to have to deal with the tag. cut mine out but the way they sewed it into the ban still left a sharp stop so I popped the threads and sewed it back. Its a huge design flaw ..

      More please

      I got these for the hubs to wear while hiking around the forest all summer long. He usually sticks with what he knows which are cotton briefs. After a week of wearing these he asked me were I got them and if I could buy him more. They have been through the wash several times now and do not look any worse for wear.

      100% convert, all hail icebreaker briefs

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

      I have been a boxer guy most of my life, so I was very hesitant to try these briefs. I tried some patagonia capilene briefs last year and was not really impressed, but these icebreaker briefs have simply blown me away with how comfortable they are. I am honestly not sure I can ever go back to my old boxers. I just ordered a second pair of these. After a weekend of rock climbing at Indian creek last week, these briefs kept my junk dry, well supported, and comfortable in my harness. I took them on a tour up Scotties Bowl this morning, and once again, dry, well supported and comfortable all the way up. I can not wait to go trail running with them once the snow starts to melt away. All hail Icebreaker briefs. Sizing is spot on. They have no fly, but I actually prefer it that way. The fly on briefs is always too small to be useful anyway, so this keeps it more simple. Just make sure you do not put them in the dryer. Washing by hand in the shower works very well, and they dry over night no problem. Would be great for a long backpacking trip.

      Love Them!

      The underwear that icebreaker continues to come up with is awesome! These are really comfortable and I can barely tell I even have them on. If you want a piece of underwear that will get you through the day without any discomfort get these now and I promise you won't be disappointed.

      Wooly Manties

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

      This was my first pair of merino underwear so I can't give a great comparison to other Icebreaker underwear or those from other brands. What I can say is that I love these things.

      When these come up in my underwear rotation, my brain does a fist pump. These things are crazy comfortable. I won't buy cotton underwear anymore. Definitely worth the extra $$.

      Why are these getting worse and worse?

      • Familiarity: I've put it through the wringer
      • Fit: Runs small

      Icebreaker had a homerun with the Beast 150 briefs, but they are not getting any points with these. Even the previous version of the Anatomica briefs were a few steps above these rags. The material is thinner, if fits tighter than previous years of the same size, which stretches the already too thin fabric. Which means they probably also won't last as long. The leg holes are noticeably smaller (in terms of circumference) as well, so they pinch my beefy cycling legs the way the previous incarnations never did. Though I need more underwear, I won't buy any more pairs of these unless I can find the old versions (or even some Beasts). Let's just hope that Icebreaker realizes their myriad mistakes and goes back to the best thing they ever did...Beast, Beast, Beast.

      How to Measure:
      For best results, take measurements over your underwear.
      Measure around the middle of your neck, leaving the tape loose.
      Measure under your arms around the fullest part of your chest.
      Arm Length:
      Measure from the back of your neck to the top of your shoulders, to your elbow and down to your wrist bone.
      Place the measuring tape at your natural waist, the narrowest part of your torso.
      Place the measuring tape around the fullest point on your hips.
