Designed for mountain biking and long rides in remote locations where extra water carrying capacity and increased storage are essential, the Backcountry Hydration Backpack adds significant capacity and versatility to mountain bike setups. It features our custom 2L fast-flow bladder, a 12L main storage compartment and an additional 2L of capacity spread across easy-access pockets. Constructed from a lightweight, breathable 3D mesh, the Backcountry Hydration Backpack features an endurance on-bike anatomic fit for unrivalled stability and all-day comfort. Two rear stretch mesh pockets provide on-the-bike storage and access for food, drinks, and mid-ride essentials, while an additional font mesh pocket and zippered device pocket keeps your smartphone and snacks close to hand. A large, roll-top compartment on the back provides serious storage and features a high-contrast reflective design and a light attachment point for enhanced visibility in all light conditions. The Hydration Backpack is available in two sizes to enable the perfect fit for all body shapes. Adjustable sternum straps ensure a comfortable fit, with further side adjustment to ensure there is no unwanted movement while riding. Hydration hose organisation loops and a magnetic clip keep the hose nearby, yet out of the way.

S/M | WEIGHT 460G | CAPACITY 14L L/XL | WEIGHT 465G | CAPACITY 14.5L DESIGNED FOR FIT The Backcountry Hydration Backpack is designed around an endurance on-bike anatomic fit, with the goal of being comfortable, secure and stable over many hours in the drops or on aerobars. The neckline is cut low to avoid chafing or getting in the way of a helmet in an aero tuck, also falling below the neckline of most jerseys to avoid rubbing on any seams. The front is shaped to be comfortable while in the drops, fitting high enough up the torso to avoid causing any chafing or impeding movement and the rear is high enough to ensure riders can still access their jersey pockets. The sides are shaped to avoid any chafing around the arms, using an open construction and stretchy materials that provide a secure fit without restricting breathing. Materials Precision Crafted using lightweight, breathable and stretchy materials for enhanced comfort on the bike. The hydration pack uses technical materials and streamlined, ‘less is more’ design principles tailored to the demands of ultra-distance cycling competition.
