Athletically shaped and technically inclined, odor-resistant Floe™ fabric wicks and cools when temps spike during aerobic activity or elevated exercise.

Athletically shaped and technically inclined, our long-sleeve tech tee keeps the core regulated during aerobic activity or elevated exercise. Built with Floe™ fabric, the material wicks and cools more quickly when temps spike. The soft fabric feels cool to the touch, sits comfortably on skin and also prevents odor accumulation. A slightly open, moderate drop neckline—along with a split side hip vent—adds cooling airflow. A half-set, half-raglan sleeve with thumbholes stays put while mid-hip, curved-hem length covers up when moving fast.
