Purpose: You don't have to avoid bathing just because you're wearing a cast or bandage. Simply apply Mighty-X waterproof leg protector for showering coverings to take a shower whenever you want. Mighty-X waterproof cast cover leg are very thin, so they are not recommended for swimming or water sports. The design team aimed to create a thin waterproof plaster cast cover that feels comfortable when showering. How to Use: Do not stretch the opening of the waterproof cover for plaster cast, but gently pull the waterproof leg cover over your cast. Carefully pull it up by the corners as high as it will go. With the help of your arms, gliding from your toes up to your knee, try to reveal any extra air left inside.
