R1 Air Full-Zip Hoody

The active insulator for high-output cold.

The R1 Air Full-Zip Hoody is engineered for the moments when you are moving fast and generating heat, but the air temperature is trying to freeze you. Unlike traditional heavy fleeces that trap too much moisture, this technical midlayer uses a unique zig-zag texture with hollow-core yarns to trap body heat while aggressively venting excess sweat. It is the ultimate "stop-and-go" piece for ski touring, winter climbing, and cold-weather running, allowing you to keep your rhythm without constantly layering up and down.
