Using your DexShell waterproof beanie is easy. Just pull it over your head for instant protection from cold, wind, and snow. It's suitable for outdoor activities like hiking, skiing, or just a walk on a winter day. When it comes to maintenance, hand - wash it in cold water with a mild detergent. Avoid using bleach or fabric softeners as they may damage the waterproof membrane. After washing, gently squeeze out the excess water and let it air dry. Don't wring it out or put it in the dryer. Store it in a cool, dry place when not in use to keep it in good condition.
