When a pack that holds only water is too small and a pack that holds everything is too big, the Siskin 8 is just right. A high-performing mountain biking pack that provides stability and comfort on the gnarliest of trails, the Siskin allows you to bring just what you need (and nothing more) on your ride. A direct-access zip path leads to an included 2.5-liter reservoir, and a U-zip main compartment opens wide to stuff a spare tube, flat repair tools, and your PB&J inside. A mesh-covered foam back panel offers ventilation and allows for lively movement while keeping your pack close to your body, even when youre riding loose. The front of the pack features a LidLock attachment point for a standard-size helmet, while side compression straps expand to fit a full face.
