Triple Eight RD Bumsaver Women's Padded Shorts help to protect hips, thighs and tailbones of roller derby skaters and skateboarders. Engineered in collaboration with professional roller derby skaters, the RD Bumsavers have an ergonomic design made for women?s bodies. Made with a double layer of solid-fabric Lycra spandex, crash pants are form fitting, while the breathable material is bacteria resistant, quick dry, and won't stick to the skin. With a convenient small inside pocket for a mouthguard, the impact shorts can be worn alone or under shorts or leggings. Equipped with shock absorbing, 10mm thick EVA foam for increased protection, each pad can be removed to customize the padding zones. Designed for women?s thinner waist and broader hips, the fabric can accommodate all shapes and sizes. Pads and shorts are machine washable (wash in cold water and air dry). Triple 8 RD Bumsaver shorts are available in five sizes to fit kids, youth, and adults: X-Small fits 22-27 inches, Small fits 26-30 inches, Medium fits 29-33 inches, Large fits 32-38 inches, X-Large fits 36-42 inches. To determine proper size, measure around waist. Manufacturer's 180-day limited warranty.
