To use these tights, simply put them on like you would any regular pair of tights before your lower - intensity workout or during the warm - up phase. Make sure to check your size using the provided measurement guide as SKINS sizing can be different. When it comes to maintenance, wash them in cold water to preserve the elasticity of the 23% elastane blend. Avoid using bleach or harsh detergents as they can damage the fabric. Hang them to dry instead of putting them in the dryer to prevent shrinkage. Also, store them in a cool, dry place when not in use to keep them in good condition.
