The Kriega x Rev'It! Barren 18L H2O backpack - co-develop with luggage specialist, Kriega - is composed of three sections: the 100% waterproof 11-litre main pack body, a 7-litre rear compartment, and an additional storage area behind the external Hypalon net. The easy-access waterproof roll-top main body offers 11 liters of space for essentials. The 7-liter zip-access rear compartment can be used to store a Tool-Roll, water bottle, or the optional 3.75L Hydration Reservoir (sold separately) to keep riders hydrated on the bike. This rear area also has a small, internal 1-liter waterproof pocket for the most valuable items. The innovative Hypalon net with elastic cord provides even more external storage for personal items or to allow wet layers to dry while riding. The Barren 18L H2O Backpack features the innovative Kriega Quadloc-Lite™ harness, which transfers weight from the shoulders to the chest and upper body, providing all-day riding comfort, even with the backpack fully loaded. The removable waist strap offers even more stability when riding. To prevent unwanted friction and heat generation on your back the backpack comes with an Air-mesh back panel for additional rider comfort. With the rugged Barren 18L H2O backpack, riders can be sure their essentials are safe and protected from the elements without compromising comfort while riding.
