Osprey has teamed up with Troy Lee Designs to bring you a limited edition version of our brand new Siskin 8, a pack that represents Troy Lee’s long history in the mountain bike scene and his recognition of Osprey’s quality, innovative products.When hauling everything is too much and only water isn’t enough, this special edition Siskin 8 is just right, allowing you to bring exactly what you need on the trail. A mesh-covered foam backpanel keeps your temperature in check and allows for dynamic movement while your pack stays close to your body. Whether you’re shredding ribbons of singletrack, sending jumps or pumping rollers, your pack will stay stable and comfortable over the gnarliest of terrain. An included 2.5-liter reservoir with a direct-access zip path keeps you hydrated and a U-zip main compartment fits your spare tube, tools, lunch and other trail necessities inside. A LidLock™ attachment point on the front of the pack fits a standard-size helmet and compression straps expand to fit a full face helmet.
