These don't fit me. I've never worn them on a bike, only briefly tried them on. One of the double belt loops on the back is unattached at the top. Liner is flannel and is removable (zippered, buttons). These have very little wear. From Icon: The big deal here is the removable and washable insulated lining, which gives you the choice: ultra-toasty, or cool and loose. The outer chassis is heavy 14oz. denim with integrated Aramid reinforced knee and hip panels, all blended together with some trick urban styling.
