This waterproof map pocket was designed to fit any handle bar. It has a zip lock closure that makes the bag waterproof. A third fastener under the bag keeps it from flopping about, but can be unsnapped for a quick view of the map. The unique hook & loop fasteners that are attached to brass snaps are the key to this unique bag. The snaps allow the hook & loop to swivel thus fitting any geometry of handlebars. The vinyl has a UV inhibitor that will last for years. This bag can be used in many other applications were waterproofing is necessary.
