Using this cap is super easy. Just stretch the elastic band and place it on your head. It'll fit snugly and stay in place while you're cycling. As for care, it's best to hand - wash the cap in cold water with a mild detergent. Avoid using bleach as it can damage the cotton and fade the bigoli illustration. After washing, gently squeeze out the excess water and let it air dry. Don't wring it out forcefully as it may distort the shape of the cap or damage the reinforced peak. Also, store it in a cool, dry place when not in use to keep it in good condition.
