Using the Giro Women's Fixture MIPS II Helmet is easy. First, adjust the Roc Loc® Sport fit system to ensure a snug and comfortable fit on your head. When you're out cycling, the helmet's enhanced cooling will keep you fresh. For cleaning, use a mild soap and water to gently wash the quick - dry padding. Don't use harsh chemicals as they may damage the helmet. Store the helmet in a cool, dry place away from direct sunlight. Remember, the Mips® Brain Protection System is there to keep you safe, so always wear your helmet properly when riding.
