A technical tank with dynamic wicking and cooling material for trail running, mountain biking or yoga.

When you’re focused on sport and trail you need to think performance first. Our straight-cut tech tank shares that same straight-ahead mentality—whether mountain running, mountain biking or practicing mountain yoga. Built with Floe™ fabric—a dynamic wicking and cooling material—the piece accelerates its material performance as body core temps rise. Bound armholes, back darts and a subtle drop tail focus on comfort, while reflective stitchwork adds visibility during those sunset or sunrise runs.
