The Osprey Stratos range is an ultra modern pack with a lightweight supportive frame called Airspeed Trampoline - a highly breathable suspended mesh which keeps air nicely flowing as you walk. This rucksack has all the essential features for making your trip a comfortable one. Stow on the go trekking pole attachment, ice axe loop and stretchy mesh pockets are available for keeping waterproofs and bottles close to hand. For those dull, drizzly days, there is a rain cover but it can be detached if weight is needing to be kept to a minimum. The perfect size for hiking or as your travelling companion.
