To use these bibshorts, simply put them on like regular cycling shorts. Make sure the seat pad is properly positioned for maximum comfort. When riding, the compression from the fabric will support your muscles. As for care, it's best to wash them in cold water with a mild detergent. Avoid using bleach or fabric softeners as they can damage the fabric and the leg grippers. After washing, hang them to dry. Don't put them in the dryer, as high heat can shrink the fabric and affect the performance of the seat pad and grippers. Store them in a cool, dry place when not in use.
