Arc'teryxPhase SL Zip Neck Top - Men's

For sweaty situations.

Most skiers bicker over cold temperatures freezing their fun-filled adventures in the resort, but as a backcountry skier, you get hot and sweaty before you freeze over, unless you're touring in the Arcteryx Men's Phase SL Zip Neck Top. This superlight baselayer uses Arcteryx's Phasic SL yarns to amplify moisture management, while drying quickly so whatever sweat is remaining can't freeze the fabric and keep you cold for the remaining tour.

  • Superlight baselayer for high-output activities
  • Phasic SL yarns wick moisture, dry quickly, and stretch
  • Form-fitting with gusseted underarms for freedom of movement
  • Tall collar with deep zip neck provides versatile ventilation
  • Smooth flatlock seams assure chafe-free comfort

Why the change?

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

I have 2 of these older version while ordering this one on sale. Surprise...they change a good thing. First the put the Arcteryx symbol on sleeve rather than a small blue rectangular name and symbol. That was a good change. However, this is a base layer. And they doubled the materiel on top and bottom of the collar seam. So now its mid layer for moderate weather...I guess. Disappointed...but will keep it. Never given this company a less than 5 stars. This time they deserve a low 4.

This is one soft shirt. It is body fitting and warm. I wore it on some rather cool summer nights while camping and it was great. I really love it!

Very comfortable and keeps your core dry. Nuff said.

Its funny how well this stuff works, for ever I believed in merino as the perfect underlayer for hiking, but I was always wet and would get cold when stopped. This layer though thinner is better, when I stop I can stay warm since my core is dry. This SL is a little thin for winter but great during the other seasons.
