Developed together with luggage experts, Kriega, the Stack 15L H2O backpack will make it possible to bring your essentials on your next short or long ride without compromising on your comfort. The easy access waterproof roll-top main body offers 15 liters of space for your essentials. The ripstop main compartment also has a small internal zip-access pocket for easy access to your most valuable items like a phone or wallet. The Stack 15L H2O also features the innovative Kriega Quadloc-Lite™ harness, which transfers weight from the shoulders to the chest and upper body, providing all-day riding support, even with the backpack fully loaded. The removable waist strap offers even more stability when riding. To prevent unwanted friction and heat generation on the back, the backpack comes with an Air-mesh back panel for additional rider comfort.
