The Kriega R25 Motorcycle Backpack ($189) is Kriega’s best-selling award-winning backpack. The pack measures 20.5″H x 12″W x 6.3″ D and has a 25-liter capacity. If needed you can add an optional 3-liter hydration reservoir and 5 or 10-liter drypacks. The harness is a quick release QUADLOC system specifically designed for motorcycle riders. The system allows for the load to be transferred to the hips and chest rather than the shoulders with traditional packs, preventing neck and back strain.
