This strap on handle bar pack has a large U shaped main compartment with HDPE stiffener for strength and stability. Like the Road Trip, the top map pocket is covered with UV resistant clear vinyl for easy on-road position confirmation. An additional front pocket has a strip of 3M Scotchlite Reflective Material and a strobe loop has been added for additional safety. Webbing tension straps go from the rear of the bag to the fork eyelets to keep the bag secure.
