Great little cover for my Garmin 201 provides an extra level of security against the elements and from losing it from my mountain bike handlebars in bumpy sections like I lost my last one.You can velcro it to your handlebars and then hook it w/a small lanyard to a brake or shifter cable in case the velcro lets go.You can also use it to hook it to Camelbak while hiking to keep it up and out of your way while still giving it a good view of the sky.
