I'm 6'3" 180lbs 32" waist with long arms and the large fits me great. It isn't ridiculously skin tight on my stick figure, but form fitting enough that it layers perfectly un…

I couldn't justify spending $90 on a winter base layer, so given the concept of layering, I decided on the $50 (on sale) lighter weight base then adding a thermal type shirt o…

The wool is very soft, but unfortunately the cut is too form fitting. I'm athletic and no flab, but like my clothes less form fitting for greater comfort. I have to return thi…

The fit is slightly bigger and longer then with the Icebreaker contour line. This is an excellent lightweight casual shirt and can be used for layering when its cold. I find…

There's probably a reason you see everyone who works at an outdoor clothing store wearing this stuff on the job. It probably has a lot to do with the fact that there is nothin…

This piece is so light, im beginning to suspect that someone filled the fibers with helium! It is surprisingly warm for its weight and when you are out in the trail or climbi…

Best piece of clothing i own. I work outside on the ramp at an airport in Maine. In the winter. In Maine. No complaints at all. These alone keep me warm and the merino nev…

I love icebreaker products. The material is soft and these can be worn for days (if not weeks) at a time without becoming smelly. They do tend to ride up though. The leg porti…

and that's a good thing. These bad boys were worn for 3 days straight out on the Carrizo Plain and Eastern Sierra. Best of of all, they did not smell at all compared to synthe…

Most comfy undies ever! I was skeptical about the fit (I like my briefs very low-cut, sexy and non-granny-panty style), but I must say that these will defs score you first pla…

Unfortunately, I bought these elsewhere on a whim and on sale. However, had I known of their superior powers of keeping the jewels cool, dry and comfortable, I would have gla…

The fabric does not seem any different than the lower priced brands. My son says he likes them but no better than the pairs you can buy for $12 to $15 at department stores.…

Who would've thought Arc'Teryx would be the one to design the perfect base? It's stupid light, breathes better than anything I've tried, wicks as well as any, AND has an SPF 5…
