This certainly is one of the best! I brought my cap 3 zip neck with me on the JMT as my baselayer! It was great. It kept me warm and was still very breathable. I really ha…

This is my 4th icebreaker shirt and it certainly hasn't let me down. A comfy slim but not quite spandex fit that goes well under everything from dress shirts to ski parkas.…

It was my first Icebreaker garment. They advertise on the odor free characteristic of merino wool, but I wanted to know by myself. I wore it for 2 weeks day and night... and b…

when you first look at this shirt it is surprising because you can see through it (unlike the capilene 3 shirt) which made me wonder how it could possibly be warmer than that…

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 never leave home without it. It is packable, quickdrying, and odor-defying. I've found the wool to be comfortable. The garment keeps it's shape very well as others have accl…

Really like the feel of it, thin, tight to the body. Put it through the stink test - wore for most of 3 days, slept in it for 2 nights. Didn't exactly smell like a rose gard…

I have quite a few icebreakers, but this one does not top the list. It isn't as soft as the others, and I prefer the ones that zip down lower. It's an icebreaker, so it's good…
- CHRIS, 12/11/11

This shirt is ok, but I prefer the the higher weight shirts. Plus, the zip on this is far less functional than the 3/4 zips available on some of their other products.…
- CHRIS, 10/31/11

I got these as a birthday present and I've worn them on all of my runs this winter. They keep your legs warm, breath well and don't smell after. That's exactly what I've bee…

Warm and comfortable, not an itch anywhere. They have an odd quality in that they are toasty in a cool room and out in the icy world. Very well stitched too - long underwear…

Just can't go wrong with Smartwool, and lightweight makes a perfect baselayer. Any heavier and I get too warm when active.…
