Osprey Talon 11 Backpack A lightweight grab and go option that can be used for a wide range of sports, the Osprey Talon 11 Backpack is a great choice for any type of outdoor enthusiast. With 11 litres of overall storage, you have plenty of room for extra layers, food for a day outdoors and internal hydration reservoir to hold water. Bonus storage comes in the form of external attachments for an ice axe and Stow-on-the-Go trekking pole loops and, importantly for mountain bikers, the Talon also uses Osprey's LidLock bike helmet system to fix your helmet to the outside of the bag. A separate compartment allows you to use a hydration reservoir if needed and keeps any moisture away from the main compartment of the bag.
