Osprey AETHER 55 Deep Water Blue backpack Customizable Comfortable Sustainable SIZE GUIDE The hiking backpack AETHER 55 by Opsrey is available at Speck-Sports. Little brother of the Aether Plus range, this Aether 55 offers you a large volume for your long mountain outings. Who says big volume, says necessarily more important load, that's why Osprey thought to equip you with many adjustment options to offer you the most comfortable backpack possible. There are adjustable straps and a Fit-on-the-Fly belt as well as the possibility to adjust the length of your back. The Airscape back panel with EVA foam padding provides a breathable and comfortable design. The main compartment is accessible through three accesses, from the top, the bottom or through a U-shaped front case opening. With a removable divider, this large compartment can be divided in two. Thus the bottom opening will give you access to the lower compartment. On the storage side, the Aether 55 will allow you to store all your gear: double zippered pockets in the top flap, front tote pocket, mesh side pockets with double access, baton holder, two zippered pockets in the abdominal belt, twin ice axe buckles. To optimize storage, the Aether 55 is also equipped with compression straps. Finally, the Aether 55 remains a highly functional and very well thought-out bag since it offers an integrated rain cover, a system for inserting the water pouch and even the possibility of attaching a Daylite model to the front for day trips. The AETHER 55 backpack by Osprey is designed for hikers looking for a backpack with a large volume, without neglecting comfort and durability.
