This isn’t your ordinary workout tee. The Men’s Active Mesh Short Sleeve was made for comfort and performance, with a relaxed and roomy fit that’s designed to not slow you down or disrupt your workout. With three performance fabrics in one, you get the natural benefits of Merino wool with the durability and quick drying time of recycled polyester (29%), plus the softness and cooling properties of TENCEL™ Lyocell fiber. Mesh ventilation at the sleeves and back keep things breathable, so you can feel good no matter how hard you push your workout.
