Icebreaker Cool-lite
Icebreaker Cool-Lite fabric combines two natural performance fibers - premium merino wool and TENCEL - to keep you cool in even the most hot and humid conditions.

Product Reviews
Rated 4 out of 5 by from Nice, but not cooler What's interesting about these is that the design in the crotch negates the lighter weight wool in two ways. One, they add a mesh layer on the inside of the crotch, which probably does wick moisture, but it also adds insulation. That whole area is hotter in these than in the heavier weight. Also, these have a closed crotch, as opposed to the access opening on the heavier model. That access opening lets a lot of air escape that these do not. So, I like these, but I bought them to be cooler than the anatomica, and they aren't.

Rated 4 out of 5 by from Great fit. Annoying lettering. Please do away with the increasingly obnoxious logos on the waistbands and keep it logo-free. It tends to ruin what are otherwise great products.

Rated 1 out of 5 by from Waistband way too wide What happened to all the awesome icebreakers I bought a few years ago? Gone are all the great colors and now we have all these styles that are too long in the legs or have something like a ridiculously wide waistband

Rated 5 out of 5 by from Gets the job done When I first took these out of the package I was concerned because the material feels like an athletic compression short more than your traditional boxer brief. Generally, this type of material is great for running but not for long days in the office. Happy to say that they were extremely comfortable and didn't bunch up or pull on my leg hair at all throughout the day. They're cool to the touch and keep my downstairs neighbors breezy and dry despite the office thermostat being locked at 75 all winter.

Rated 5 out of 5 by from Boxer Brief Heaven These boxers keep there form and stay comfortable all day. I hope to replace all my cotton boxer briefs with Icebreakers someday.

Rated 5 out of 5 by from Excellent feel and Quality I've tried all kinds of underwear and material. Wool, nylon, rayon, etc. These are by far my favorite thus far. The feel light enough that my movement is not restricted, but sturdy enough that the are comfortable, durable, and sweat absorbing. And I say that last part with confidence because I am a sprinter and sweat profusely.

Rated 4 out of 5 by from Now I understand Icebreaker underwear Very comfortable Icebreaker!! Great job and now I understand why people shell out for these. The only thing I don't get is why not just make all of them with a "fly" for a guy. Lightweight, dries fast, barely notice they're there, and comfortable...just make sure you order the ones with the "fly" for obvious ease of use.

Rated 5 out of 5 by from From socks to briefs, onward and upward! I hadn't tried merino boxers before, but wearing merino socks for a few years without problems with itching helped me decide to try. It was a decision that was overdue as the briefs were equal to the socks. These briefs gave me comfort, breathability, and mobility. I should have made the decision sooner.
