Fast, technical, dynamic, and built with Floe™ fabric that wicks and cools quickly when logging high miles or pounding out sweaty workouts.

Fast, technical and dynamic, the Icefloe is not your standard athletic wicking tee. Built with our Floe™ fabric technology, the material wicks and cools more quickly when core temps spike. The soft fabric feels cool to the touch and sits comfortably on skin when logging high mileage days while also preventing odor accumulation after sweaty workouts. Flatlock seams reduce friction and a subtle droptail adds coverage. Reflective logos and stitchwork provide visibility when running or riding at dawn or dusk.
