The On Women's Climate Shirt is light, warm and keeps you sweat-free. This shirt adapts to your body temperature, insulating your skin on brisk mornings and airing it as the sun comes out. The special waffle fabric absorbs sweat fast and dries even faster, keeping you fresh and comfortable. Stay free as a bird with the four-way stretch fabric, for unrestricted movement and track times in a tick with fiddle-free thumb- and watch holes, without exposing your skin. The On Women's Climate Shirt is the essential mid-layer that keeps you doing what you love.
