Reliable all-weather protection for bike commuters, it’s becoming a favorite for a wide range of other uses too. New suspension provides increased versatility and comfort. Featuring PVC-free exterior, the unique roll-top SealLine Urban Backpack provides watertight protection around town and on the trail. Made of PU-coated polyester and scrim-reinforced urethane, the Urban Backpack comes in two sizes–small (17-liter volume) and large (37 liters). It includes an innovative QuickClip closure for easy, one-handed fastening/unfastening, as well as SealLine’s Modular Accessory Pocket system for attaching optional add-ons, such as a Zip Pocket or Mobile Electronic Case. Other features include breathable, ergonomic shoulder straps that combine with a sternum strap and hideaway waist belt for a comfortable, supportive fit; a breathable, waterproof back panel; and an external pocket and carry handle.
