Using the Swift Cap is easy. Just put it on your head and adjust the strap to get a comfortable fit. When you're out for a run, workout, or any outdoor activity, this cap will keep you dry by wicking sweat and cool by venting heat. Also, it'll protect your head from the sun. As for care, you can hand - wash it with mild detergent in cold water. Don't wring it out too hard. Then, let it air - dry. Avoid putting it in the dryer as high heat may damage the materials. If you're wearing a helmet, make sure the low - profile design of the cap fits well under it before starting your activity.
