Ideal for anyone in need of a pack with a fine-tuned fit, the Osprey Aether 55 Backpack is suitable for a variety of body shapes and sizes. Custom Fit-on-the-Fly™ shoulder straps, hip-belt and adjustable torso length offer an adaptable, comfortable fit, while an injection-moulded AirScape™ back panel delivers breathable, close-to-body performance. Perfect for longer, overnight adventures, the spacious design features multiple compartments and pockets, including a designated hydration reservoir sleeve and area for your sleeping bag. Compression straps also help to limit the bulk so you can move with ease, and dual ice axe loops with bungee tie-offs ensure you are ready for whatever the terrain has to throw at you.  Additionally, it is made with Bluesign®-approved Nylon and a PFC-free Durable Water Repellent coating.
