Top3 in base layers
My three favorite materials for base layers are capilene, polartec power stretch and phasic, which is what this shirt is made of. I do landscaping so I'm always either sweating in the heat or getting sprayed by sprinklers in the summer. In the winter its snow removal. The quick drying phasic material makes quick work of moisture, keeping me dry all day in almost any condition. Obviously this shirt doesn't give a lot of insulation, so for colder climates get the phasic ar or sv. Fit is great, and every piece of arcteryx gear is top notch. Recommended highly

Very comfortable shirt, when I wear it, I feel very soft and comfy, it's so breathable and quick dry. But it fits me a little small. And I believe it's smaller than other Arc'teryx shirts, So I have to get a larger size one. At last, it has a high quality.

exactly what you would expect from arc'teryx.....
shirt is truly excellent for having no spandex/latex, it is super stretchy. very comfortable drys quickly distributes moisture better than any shirt i have owned has a nice fit is extremely light weight is really durable, i got it snagged a few times while rock climbing and it didn't rip (the stretchiness kept it from ripping or tearing the threads) the price is steep, but its worth every penny for the quality of it. nowadays most manufactures sell there items for high prices, solely based on it having a "popular name" or it being "in-fashion". not arc'teryx, the price of there merchandise is based on its quality and manufacturing cost. although there is nothing non-stylish about this shirt, i truly like the style and fit of it. thinking of buying another one to toss in my pack for extended expeditions. :)

The height
It is a product. Arc 'teryx is not betrayed. It is a brand that always builds the pantheon of products. There is no cold even if sweating in the snow mountain. If the comfort is requested, it is this. It finishes being recommended at ease.
