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 backpanel offers ventilation and allows for lively movement while keeping your pack close to your body, even when you’re 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.
Includes Osprey's LidLock helmet carry for traditional helmets and front panel upper compression straps for full face helmets.
Osprey Hydraulics® LT 2.5L reservoir keeps you hydrated all day long and stores in a dedicated hydration compartment to protect pack contents from accidental spills.
Multi-pocketed tool organization and large bucket main compartment stores and protects all your essential gear.
Our rolled, soft-edged harness contours to the upper shoulders to keep the pack close to your body and provide stability.
