This is the BLUE LUG original ankle band "SNAP ROLLY/Snap Rolly". It's a band to prevent your pant cuffs from getting dirty on the chain or getting caught. It's a classic one-touch type that wraps around quickly when snapped onto the desired position. The material is richly textured waxed cotton. Perfect for commuting, shopping, and touring. The items in the photos are all that is included. No returns or exchanges, please.
