    Travel the world or stay at home with this cozy pair of boxers.

    Icebreaker put comfort first in its Men's Everyday Boxer With Fly. Made with merino wool, this boxer regulates your body temperature, is non-itchy for comfort, and stays fresh after extended use even when you can't wash it between wears. Icebreaker removed the back seam for comfort, used flatlock stitching to reduce bulk, and added a gusseted crotch for mobility. A functioning front fly finishes this boxer for a wide range of comfort and accessibility whether you're drinking beer on the sofa or beginning your second day on a multi-day excursion on the mountain.

    Superb comfort

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

    Way better than cotton boxers. Super comfortable when climbing, running, or just sitting in the office all day. They dry quickly (even after swimming) and don't really bunch up like cotton boxers. They run a little bit small and the durability can be an issue if you wear them a lot.

    Overall, I would highly recommend trying a pair.


    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: Runs small

    I live by these boxers. Once I moved to them from cotton, there is almost no going back. I've worn 5 pairs about 60% of the time the last 2.5 years.
    Pros: they dry quickly, while you wear them. Getting sweaty doesn't leave you with swamp ass for the rest of the day. As with all merino, they don't smell. Size may run a bit small.
    Cons:Durability is a bit of an issue. I do wear these a lot, but I usually run a hole through them in about 1 year of regular wear.

    I love my Icebreaker boxers, but...

    • Fit: Runs small
    • Size Bought: medium

    Don't get me wrong these are nice, but of *all* the Icebreaker Boxers that I own this model (Men's Everyday Boxer With Fly) in size "medium" is the most SNUG medium of all--just FYI.

    Best underwear ever!

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

    If they weren't so expensive I'd have a whole drawer full! And give them 5 stars. Super comfortable, light, and always the right temperate. Never get any swamp-crotch hiking, playing basketball, snowboarding, anything! I'm 5'10", 165lbs, 30' waist and the S fits snug, but just right and my girlfriend loves them. Cotton is so civil war. Wool is the way to go.

    Great comfort and performance

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

    Compared to my other pair of wool boxer briefs—the SmartWool Microweight—the Icebreaker's are definitely shorter and fit more snugly. The fit is more like cotton briefs, so if you prefer more leg room and length, go for the SmartWool style. I find that I like both just about equally and enjoy these for daily use, as the name implies.

    They feel great on and go for days without holding odor or causing irritation, exactly what an expensive pair of wool underwear should do.

    New version is too short

      Like one of the other reviewers, I wear these every day. The ones I bought 2-3 years ago finally wore through -- to my great disappointment, for they were THE BEST. I bought three new ones, and unfortunately the inseam is too short. Now they ride up a lot, and are very uncomfortable.

      Please bring back the old fit!

      No Stink, Good Price!

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

      I'm 5'10" 165lbs with a 33" waist. I wear a Medium in all styles from Icebreaker. The Everyday Boxers are snug around the quads and thighs but never tight

      The Everyday Boxers uses a fabric weight of 200gm making them a true year round base layer bottom while still being breathable enough for summer use. While I prefer the 150gm weight for summer use, the 200gm weight was surprisingly fine for a hot day hike to Lake Ingalls, 2500 gain and 9 miles. I originally thought I was going to roast in the 200 weight boxers on this hike, but I decided to wear them anyways, and was truly happy that the boxers proved me wrong.

      If you're looking for an alternative to smelly synthetic underwear, Icebreaker'd Everyday Boxers are one of the most comfortable ways to go!

      I have three pair of these and have worn them every single day since I got them a year ago. So soft and comfortable. From Texas summer heat to sub-zero Colorado mountain tops, nothing is better. Tried wearing a pair for 6 days straight once to test the merino. No stink!

      I'm 6' 185lbs. Large is very comfortable. Not athletic-snug. Just a super-comfy pair of boxer-briefs. Great length too.
