How to use: Just put on the shorts like you would any other pair of shorts. The two - way stretch shell allows for easy movement, so you can pedal and maneuver on the trail without any restrictions. When you're done riding, you can take out the padded liner if you want to make the shorts lighter and more comfortable for off - bike activities. Attention: Avoid sharp objects that could tear the shell of the shorts. Also, don't use harsh chemicals when cleaning them. Maintenance: You can machine - wash these shorts on a gentle cycle. Use a mild detergent. After washing, hang them to dry. Don't put them in the dryer as high heat might damage the stretchy fabric and the padding in the liner.
