The Columbia Baselayer ½-Zip Top's midweight fabric keeps your torso cozy on chilly winter days (you know, when it isn't nose-hair freezing or bluebird-sweaty). Unzip the front in preparation for a hard mogul run or a dawn patrol.

  • Omni-Heat reflective dots line the inside in the places where you need the most warmth
  • Omni-Wick treatment in high-sweat zones so you won't feel soggy after a black-diamond run
  • A form fit and thumbholes so you can layer easily on top
  • Antimicrobial treatment helps fight the funk

Not as impressed with the shirt as I was with the tags and the look of the inside. It fit true to size, the length is really nice. It's a good layer, but I didn't really notice anything special with the awesome looking Omni-Heat. I used it while sitting, not moving to try to keep warm and I also used it while working out. I used it as a base layer, a single layer, an outer layer... It seemed like a typical layer.

Super warm!

Fits very well. Keeps me extremely warm and wicks away the sweat!
