To use these Endura women's padded liner shorts, simply click the seat pad into place using the Clickfast attachment system. Then put on the shorts like you would any regular pair. For the best fit, make sure the waistband sits comfortably around your waist. When you're done riding, detach the seat pad and turn the shorts inside out. Machine - wash them in cold water with a mild detergent. Avoid using bleach or fabric softeners as they can damage the fabric and the wick treatment. Hang the shorts to dry; don't put them in the dryer. Also, check the seat pad regularly for any signs of wear and tear. If you want to switch up the shorts, the seat pad can be easily transferred to other compatible Endura mtb cycle shorts.
