Developed in collaboration with luggage specialists Kriega, the Stack 15L H2O Backpack is designed to handle everyday riding, commuting, and longer journeys with ease. Clean in appearance and highly functional, it offers reliable waterproof protection while maintaining excellent comfort on the bike.

The easy-access waterproof roll-top main compartment provides 15 litres of storage for your essentials. Constructed from durable ripstop material, the main compartment also includes a small internal zip-access pocket—ideal for securing valuables such as a phone or wallet. Behind the waterproof liner, the backpack is compatible with a 3.75L hydration reservoir (sold separately), allowing you to stay hydrated while riding or once you reach your destination.

Comfort is enhanced by the innovative Kriega Quadloc-Lite™ harness system, which transfers weight from the shoulders to the chest and upper body. This significantly reduces fatigue, even when the backpack is fully loaded. A removable waist strap adds further stability, while the air-mesh back panel helps minimise heat build-up and friction for all-day riding comfort.

With its clean styling and practical design, the Stack 15L H2O Backpack keeps your gear protected from the elements without compromising comfort—making it a dependable choice for riding from A to B.
