A high-performance option for mountain bikers, the Osprey Siskin 8 has 488 cubic inches of streamlined storage, a lightweight but supportive suspensions system, and a built-in 2.5L hydration system.
The pack’s suspension consists of a foam framesheet and a channeled, mesh-covered Airscape backpanel. A padded, mesh-wrapped harness provides carrying comfort while staying out of your way when you’re riding. A removable webbed hipbelt works in tandem with an adjustable sternum strap to help you dial in fit.
The interior of the pack is accessed by a large U-shaped zipper, while a separate compartment holds the included Hydraulics 2.5-liter reservoir with direct-zip access. A magnetic sternum strap bite valve attachment is included so your hydration hose remains securely in place but close at hand. There are also tool organization options and an internal scratch-free heat-embossed slash pocket protects phones or sunglasses.
On the exterior of the pack, there is a fabric shove-it pocket for bulky or wet gear. A dedicated bungee lets you attach a traditional biking helmet while the upper side compression straps double as a system to carry full-face helmets. A blinker light attachment point lets you add a light (not included) for better visibility in low-light or at night.
The Osprey Siskin 8 hydration pack is available in your choice of colors.
