How to use: Slip these shorts on before your warm - up for team sports or any medium - intensity activity. They're perfect to wear under your regular sports kit. When measuring for size, use a measuring tape to get accurate dimensions as described in the size guide. Remember, SKINS sizing can be different from normal sportswear. Attention: Always check the size chart before purchasing to ensure a proper fit. Avoid sharp objects that could tear the fabric. Maintenance: Wash the shorts in cold water with mild detergent. Don't use bleach. Hang them to dry instead of using a dryer to keep the fabric in good condition.
