Perfect layer for snowshoeing
I have used this during a week of near zero snowshoeing in Montana (in and out of Yellowstone) as well as during a week of 20-30 degree snowshoeing in the Uintas east of Park City. Great layer in both cases. Maintains warmth, sheds sweat, and does not pill.

New Favorite Layer
Super comfortable and so warm!! Been missing out for 34 years of my life without a half zip layer like this. dang. . . The material is incredibly soft, it breathes very well, and fits me great. Pair it with the same lower baselayer as well!
