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…

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…

The Arc'teryx Phase series baselayers are awesome! Soft, bomb proof and true fit. Sleeves and hem are long. If you are looking for warm I would go with the Phase SV. 6ft 180l…
