This is a dedicated cover for the Impact Shield, designed to gently protect your hands. The material is water-repellent twill fabric (35% cotton, 65% polyester). It repels water and dirt while absorbing vapor such as sweat, and is easy to handle as it dries quickly and resists wrinkles. We are particular not only about functionality but also about the appearance, and have finished it with a simple design that blends into the space. Each one is carefully made. - Dark colors may fade during washing. We recommend washing separately with a neutral detergent.
