Patagonia R1 Air Zip-Neck Top - Men's | Raptor Brown

Dropping temps be damned, the lightweight, breathable Patagonia R1 Air Zip-Neck Top allows us to push our bodies to the limit in cold, winter weather without losing a step. This is made possible thanks to the recycled hollow-core fabric with a unique zig-zag texture that wicks sweat from our skin, dries insanely fast, and maintains high levels of breathability to keep our muscles warm as we reach for new PRs, whether we're on the skin track or a road run.
