Sizing notes

Measurements are stated in inches unless otherwise indicated.

If your body measurements result in different sizes, we recommend using your chest measurement for tops and your hip measurement for pants.

Rated 5 out of 5 by from Best underwear - pants down! Will only buy Icebreaker underwear from now own. Boxer briefs are no-ride, super soft and comfortable, and importantly, breathable. Not ashamed that I rewore without washing and there was no stink.

Rated 5 out of 5 by from Great for my trips to Itsly When My husband and I travel we always pack very light. I make sure He takes 2 or. 3 merino boxers even if we are going for 40 days or more like when we walked the Pilgrimage Trail, Santiago de Compostella, in Spain, because He wears one pair and washes the other and they dry so fast, especially if you roll them in a dry towel at the hotel and step on them- they are almost instantly dry. Now, one problem with Ice breaker is the material is very thin and have had problems with them getting holes. But it's probably because I wash them so much. You know they say you don't need to wash them / just air them out, but personally, I just have to wash them daily. Now I don't wash the merino Shirts every time he wears them, but do wash the boxers every time. One thing about it, NEVER PUT THEM IN THE DRYER. Also, I always go a size up because My husband likes a looser fit.

Rated 4 out of 5 by from still the best underwear I can find I have been wearing IB underwear for the past 4 years. Just retired my oldest pairs (with many holes on them) a few days ago. Compare to some of the older ones, the new underwear feels a bid snug and lower waist. A big improvement is the tag at the back of waist band is gone which sometime caused itchiness. A bit on the pricy side, but it will provide great comfy service.

Rated 5 out of 5 by from Best boxers Ever since walking the Camino de Santiago two years ago, I've been wearing Icebreaker boxers. Comfortable and durable, they also hang dry quickly. I can't imagine wearing anything else.

Rated 1 out of 5 by from Where is the support? There isn't much to complain about other than the lack of support. The band isn't noticeable and the materials used are on par with all of the other Icebreaker products. If the design team can figure out how to give the boys the support they need then this will be a winning pair of boxer briefs. I ordered a pair and had to return one knowing they were not going to get used. I no longer wear the one due to the constant frustration with readjusting.

Rated 5 out of 5 by from Most comfy I have been wearing the same brand of undies since high school. I finally made a switch, and these made me a believer. After getting a sweat on, I was surprised to realize my sweat pants were soaked, but these undies kept me cool and dry. As others have suggested, the seam up the crack was a bit concerning when I first pulled them on, but after a few moments, I stopped noticing, and the lack of seams to rub is pretty awesome.

Rated 4 out of 5 by from A great trek and travel choice! I wear these boxers year round and always take them traveling - especially trekking in Nepal. They are comfortable, easy to wash and dry quickly, do not hold odors. They take up little space in packing gear for treks and travel, including hiking in summers, skiing and outdoor activities in winter. I could only offer one downside and that is they wear out near the crotch seams before anywhere else.
