This isn’t your ordinary workout tee. Our 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.
