I bought this product to put under the Marmot Super Hero Jacket for snowshoeing. I'm 5'9" weigh 175 and wear a 41" suit jacket. The medium fits me great. I like the high ne…

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…

Love it under another layer of icebreaker. Wish my parents were Merino sheep no offense ma and pa so I would never run out of this product. Giving plasma every week to be a…

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…

Its true what they say. This is my first Merino wool item, and it does cool me down when im hot, and warm me up when im cold. The quality of this product for something so thin…

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.…

I'm a bigger dude, but this shirt is pretty tight. Large in Arc'teryx is my normal size and I almost wish I got an XL this time. The neck is not constricting though - so I am…

I've had Arc'Teryx wool, Icebreaker, Smartwool, and a handful of the other 'big names' and hands down Arc'Teryx makes the best wool. It's the strongest, lasts the longest, loo…

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…

It was hard to believe while I was wearing this shirt that a fabric that you can see through can be wind resistant and as warm as it was. I was out running in the mid 50's an…

I bought shirt for running and it's kept me warm down to about 35 degrees. I get cold easy, so your mileage may vary. I run 30-35 miles a week mostly on the pavement. This is…

Soft and smooth hand, nice form-fitting cut but not too tight; runs true to size (5'8" muscular 190, med fits good). The "silk weight" refers to the lightness of the cloth, an…

Lightweight and breathable, this shirt is great in the summer. Keeps you dry and dries fast when wet. Great while wearing a pack or during any physical activity. I'm 5'6" 150…

I think that this material is best for base layer shirts and i'd rather some north face tights but the product is alright. Then again it's a personal opinion.…

I needed to stock up on bottoms - because its getting colder in the winter (or maybe I'm just getting older). I have always been a fan of Arcteryx and Patagonia as far as the…

I remember a lot of the old itchy wool long johns from childhood. This stuff is a lot more comfortable (and with the merino blend, not itchy at all). This is not the first…

This wool product is very comfortable and is satisfied enough functionally. It is comfortable even if I sweat. I recommend it…

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…
