When you can't be sure of the weather, be sure of the Climate Shirt

It's light. It's warm. It keeps you sweat-free. It's the fast-drying game raiser for cold morning runs.

Features of the Climate Shirt

Technology

Nevermind the weather. The Climate 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. Running or hiking. For as long as you can go.

Materials

The light fabric is knitted with a 3D effect, absorbing moisture faster than most running shirts. Warm in the cold. Cool in the heat. It's the essential mid-layer that keeps you doing what you love. And made with fully recycled polyester, it's as mindful of the planet as it is you.

Design

Designed for long-haul runners and all-day trekkers, On has given it everything so you can do anything. Stay free as a bird with the four-way stretch fabric, for unrestricted movement. Track times in a tick with fiddle-free thumb- and watchholes, without exposing your skin. Action. Packed.
