The Transition Wrap is a multipurpose changing towel and seat cover to fix this very problem. Just zip up the removable hoodie and slip over your headrest for a secure mount to your seat post workout. When you're ready to change from work clothes to workout clothes at the local trail, just secure the belt around your waist and the towel will stay put! It’s machine washable, built to last a very long time, and comes in a bunch of fun colors too.
