Like to ride in the rain, but your GPS doesn't?  No problem!

This waterproof bike combo will keep your GPS dry.  The mount fits handlebars from .75 to 1.5 inches in diameter.  The case measures 5.5 x 3.5 x 1.7 internally.  This means all 4.3 inch and 3.5 inch GPS units (that's 98% of the GPS market) will fit fine.  The case is zipper shut and maintains a weatherproof seal.  The lens permits human touch which means that your touch screen device will work fine when inside the case. A built-in port is available to run cables through if desired.  Included are a set of foam inserts to help cushion smaller GPS units and get them snug against the film so it doesn't move around.

The case and the mount are easily removed.  The mount is attached using a heavy duty adjustable thumbscrew attachment.
