Designed to do it all—and hold just enough gear—the Siskin 12 is a mountain biking pack with many of the high-performing features you’d expect from Osprey.
The mesh-covered AirScape backpanel provides excellent ventilation and maximum range of motion—go ahead, get sendy.
A LidLock attachment on the front of the pack can store a standard size helmet while side compression straps expand to hold a full face helmet.
The main U-zip compartment houses organization pockets for your bike tools and room for a layer, a sandwich, or some light mountain bike padding.
Rolled, soft-edge shoulder straps keep the pack stable over technical terrain and ensure no pinching points when full.
A dedicated compartment holds an included 2.5-liter reservoir and zippered hipbelt pockets provide easy access to bars during the ride or a bottle opener afterwards.
