Osprey Siskin 8 Hydration Backpack

The Osprey Siskin 8 Backpack features the neat Lidlock helmet attachment for when its not in use and a non-scratch pocket specifically designed for carrying sunglasses or a mobile phone. The 2.5-litre Hydraulics LT Reservoir uses Ospreys brilliantly simple magnetic bite valve, which grabs onto the sternum strap magnet so that the mouthpiece is always to hand and can be accessed on the go without looking away from the trail.
