The Arc'teryx Phase AR Crew Long Sleeve is a mid-weight, crew neck base layer appropriate for cooler temperatures, high-output activities. Composite construction of Phasic AR and Phasic SL fabrics in addition to the textiles construction and next-to-skin fit eliminates excess bulk and rapidly transfers moisture for efficient evaporation. Benefits include improved temperature regulation and layering.

After you sprint up a skin track or flash up a big wall while wearing the Men's Phase AR Crew, you'll wonder how you wore any other baselayer. Arc'teryx used two types of soft, comfortable Phasic fabric when it engineered this next-to-skin top: one fabric helps sweaty moisture move away from your skin, the other fabric aids temperature regulation. A carefully crafted fit and a host of performance features complete this multi-season foundation layer.

Arc'teryx Phase AR LS Crew Reviews:


These are good baselayers, I have several of them in M and L. I'm 5'10", 165lbs, and the small would be skin tight, the medium fits tight and athletic, like I would like a baselayer to fit, and the large fits like a sweatshirt, and I will wear it as a thin, long sleeve shirt sometimes, just for the extra warmth, on something like a summer camping trip where it gets a bit chilly at night, but not cold enough to need a jacket. The material is very high quality, draws sweat away from the body very well, and it's incredibly light. I love the carbon copy color, it looks great. Good buy, probably not worth the asking price though, just like most Arc'teryx gear, but on sale, go for it.

This is now my goto base layer for backcountry skiing and trail running in the winter. I was previously a diehard merino wool fan (Icebreaker and Smartwool)... while I love the 'non stink' factor, I found that it retained the moisture from my sweat and left me feeling cool when I stopped. The Phase material both wicks well and dries quickly.
I wear a medium in the Phase lineup and also in Icebreaker and Smartwool tops.

This layer is wicked for touring, its as they promised, a moisture mover and a warm layer at the same time. I used to love merino but was always wet when I stopped and I would get cold. This baby moves moisture when I am sweating and gets it away from the core, then when I am stopped I am dry and warm. perfect for ski touring which is such a warm/cold sport.
