• Please note that all the info provided refers to body measurements, and NOT the dimensions of the garment.

• If your body measurements are midway between two sizes, go to the smaller size for a tighter fit or the larger size for a looser fit.

• If your body measurements result in different sizes, Icebreaker recommends using your chest measurement for tops and your hip measurement for pants.


Chest - Place the measuring tape around the fullest part of your chest.

Waist - Place the measuring tape at your natural waist, which is the narrowest point on your torso.

Hips - Place the measuring tape around the fullest point on your hips.


Slim Fit - A snug, close-to-the-body fit for low-bulk layering.

Regular Fit - A fit that is neither snug nor loose. Garments with this fit can be worn solo or over other layers.

Relaxed Fit - Loose-fitting lightweight layers. Ideal for more casual use.

* You can find the fit info for Icebreaker styles in the product description features and specifications.

Rated 2 out of 5 by from Fits Poorly Where It Counts I've owned a lot of Icebreaker underwear, but this pair is the worst. The legs stretch out, the legs are too short, and worst of all, there doesn't seem to be enough room in the crotch for everything down there. It constantly shifts side to side and eventually end up falling out and no amount of adjustment can save it. I compared them to an older pair and Icebreaker really cut out a lot of material from the crotch area. The quality of material is predictably great, but until this fit issue gets sorted out I'm not buying any more icebreaker underwear.

Rated 1 out of 5 by from Not for Backcountry Use First off the pair of underwear does what Merino Wool should do, keep dry and not smell. That is all this pair is good for. They fit great, however after extended use and movement they will begin to ride up into your crotch and no longer become comfortable. You will spend endless amounts of time picking this underwear out of your butt and the creases of your crotch. By the end of your trip you will either burn this pair of underwear or throw them away. The money spent on this product is an absolute waste. With better construction and design this product could be improved.

Rated 5 out of 5 by from Oasis vs. Anatomica/Everyday So far I have tried the Anatomica boxers w/fly, the Everyday boxers, and the Oasis boxers. The Oasis are by far my favorite. The Oasis line in general seems to have the best fit for me (not a bodyfit/muscle fit, but a nice athletic/tailored fit) and the Oasis boxer has the one very important feature - no center back seam - i.e. no/less wedgies. The center back seam on boxer/boxer briefs pretty much means they're going to be riding up on you if you're doing anything active. The Oasis is the only pair of boxer briefs I own that don't ride up under normal, active use, and that alone will keep me buying these boxers. While they are the most expensive of the ones I've tried, I really believe the extra couple bucks per pair is worth it considering the area they are keeping comfortable. If I were on a tighter budget, the Everyday boxers would be my 2nd choice as they are comfortable as well and I think I just prefer the 200gm weight to the 150gm, but I would not recommend the Anatomica due to the riding up factor. If I were to rate all 3, I give the Oasis 5/5 for active comfort and daily use comfort, the Everyday 3/5 for active comfort and 4/5 for daily use comfort, and the Anatomica 1/5 for active comfort (permanent wedgie) and 3/5 for daily use comfort from my personal experience. For reference, I am 6'1" 180 with an athletic build (rock climber, mtn biker, trail runner) and wear size Medium in all pairs of Icebreaker boxers. Medium gives me a closer, more fitted feel and support.

Rated 2 out of 5 by from Fine if the fit works for you. Quality product. Leg length is too short with loose openings and waist is on the tight side for the size for me. Although Icebreaker is my go to brand for shirts I prefer another brand's underwear due to fit preference. I'm 5'10" 165 lbs proportionally athletic build and tried the Med for reference.

Rated 5 out of 5 by from Perfect Skivvies? Soft comfort and good fit. Size M works well with my 33 inch waist. Surprisingly comfortable even in summer. This wool breathes very well - never clingy in humid weather. Easy care - machine wash and air dry. Have I found the perfect skivvies?

Rated 5 out of 5 by from Extra warm and comfort for the winter These were just what I need to wear under my cycling tights and running gear this winter for a bit more warmth - and they are incredibly comfortable.

Rated 4 out of 5 by from Oasis Boxer This is a little thicker material than I originally expected but very good quality! Probably more for cold sports than everyday wear but all in all a great quality item as always from Icebreaker
