Rated 5 out of 5 by from Finally a REAL solution to my chafing issues Too many ambitious long distance hikes of mine have ended not because I ran out of steam, but because I could no longer stand the pain of my legs and balls chafing on each other. At the end of some hikes my skin would look like raw hamburger. Sorry, not trying to be gross, just explaining how bad it was. Applying vaseline and gold bond only got me so far. I've only taken these briefs out on one solid hike, but the results were a nigh and day improvement over any hike before. No irritation at all in that region. I did however learn that some of my chafing is from my thighs rubbing together, so I suppose I should also look at getting the longer version of these same icebreakers.

Rated 5 out of 5 by from Super lite and comfortable! Have this Icebreaker brief in other colors and stripes, super lite weight fabric that draws moisture away from the body and offers proper support in a minimal cut. Perfect under lower fitting jeans and shorts.

Rated 4 out of 5 by from If briefs are your style, these briefs are for you Generally I don't where briefs, but with athletic thighs (see: stacked quads) this are great when wearing pants that are more form fitting or you just don't want the bulk of boxers or boxer-briefs around your legs. Icebreaker Merino is top notch, per usual. Buy a pair of these and you can't go wrong.

Rated 5 out of 5 by from THE BEST UNDERWEAR EVER. I have 3 pairs of these and they are perfect. I can wear them working out, hiking, or just casually. Look amazing, super comfortable, the perfect weight, and no stink. I am slowly going to replace my whole undie drawer with them. Love the colors!

Rated 5 out of 5 by from Anatomica = Awesome I now own 10 pairs of these, and one pair of the boxer briefs. The boxer briefs take me back to my junior high days of wedgies. You will need duct-tape to keeps those things from riding up. However the Anatomica Briefs are the Cat's Meow. Comfy, stay put, no funk, good for multi day use, no chaffing, and the best part; the wife likes them. These are expensive, but if you catch them on sale they are worth the price. They run true to IceBreaker's size chart. I'm a 34" waist, and the Larges are fine.

Rated 5 out of 5 by from Great Fitting, Lightweight Briefs I've used the IB briefs for running and soccer, and they are quite comfortable, with a great fit and good support. They have a very light feel, so you almost don't know you're wearing them. The seat stays seated, so no wedgies, and the pouch does what it's supposed to (with a slight shift to the left). They sit low on the hips, so if you're in to showing off your underwear logos, these might not be the briefs for you (but the no show logo does avoid having strangers ask questions about your ice pick). If they were a little less expensive, I might even toss out my everyday undies and replace them with these.

• 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.
