20-liter Welded-Waterproof Pannier works on and off the bike. The pannier bag itself is hardware free. Each bag comes with a Knurled Welded™ rack adapter that affixes to most racks. This keeps the hardware on the bike not the pannier bag. Off the bike, the Saddle Bag Rolltop Pannier is built to be carried comfortably on the shoulder with included shoulder strap or as a tote using the 5-bar haul handles. Made for adventure biking and all-weather commuting, the lightweight Saddle Bag Rolltop Pannier is 100% waterproof. Includes integrated laptop sleeve, five-bar haul handles, and Hypalon® MOLLE system. Guaranteed for Life.
