Sweat less, ski more.

Layer the Arc'teryx Men's Phase AR Bottom underneath your shell and know you'll stay dry and warm on your next cold-weather adventure. Lightweight panels at the back of the knees and a gusseted crotch ensure you have freedom of movement while you hike, ski, or climb, while the hard-working main fabric ferries moisture away from your skin to keep you dry.

  • A baselayer bred for active days in sub-freezing temps
  • Stretchy, supple fabric wicks moisture under a shell
  • Wide waistband lays flat and won't bunch

These are the most comfortable....

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Small

These things are so comfortable and warm. I didn't think there were better base layers than Under Armour cold gear for warmth. But I found them. These things rock.

too tight in the legs?

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: medium

I am still testing this item. I have used it twice no and it fit perfectly in my waist but I have large legs and it was really tight in my thighs. I am going to try to stretch it out. It was very warm and comfortable when I ran with them . Would definitely recommend buying these.

Arcteryx Phase AR Bottom

  • Familiarity: I've put it through the wringer
  • Fit: True to size

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.

The AR bottoms are nice on most moderate days underneath my Arcteryx Fury AR soft-shell pants.

I wear a medium in the Phase lineup and also in Icebreaker and Smartwool bottoms.
