Cotton Sports Wristbands. Crafted from premium, breathable long-staple cotton, these athletic sweatbands are engineered to rapidly wick away moisture during high-intensity training, tennis, basketball, running, or gym workouts. The plush fabric blend offers a soft, non-irritating feel against the skin, while the heavy-duty elastic weave ensures a secure, non-slip fit that retains its shape and elasticity wash after wash.
