The two-part construction of this saddlebag for world-traveling cyclists consists of a lightweight, waterproof pack with a roll closure, buckle closure, and air release valve. It features a strap with a bungee cord and gear loops on top, as well as a reinforced bottom that makes loading and unloading quick and easy during short breaks, as the bag can be removed while the strap remains on the bike. The two buckle straps and two Velcro fasteners adjust to a variety of frame sizes and tube diameters, including carbon bikes.
