Product Information

Designed for lightweight, ultra-breathable performance

Designed with lightweight, ultra-breathable performance in mind, the Exos 48 Rucksack strips away heavy and restrictive foam and focuses on user-defined features, allowing you to tailor your pack on the trail. Osprey's exceptional, fast and light assault pack is built for unrestricted comfort.

The ExoForm harness and hipbelt are constructed using mesh throughout to significantly reduce weight and maximise comfort. The outer layer is an open mesh and the core is a multi-layered spacer mesh for extra padding, creating incredibly gentle body contact along with an exceptional level of ventilation.

A high-tensioned mesh across the aluminium alloy frame of the AirSpeed back system allows plenty of rear ventilation while keeping the load close to the body to retain stability and without conceding weight.

Remove the lid, the key straps and the attachment points, and the weight is stripped further for ultra-fast use. The integrated FlapJacket closure system provides weather protection while the pack is lidless.

Integral frame is incredibly comfortable. Pack is very light but looks tough enough. Side compression straps mean it is suitable for smaller loads too.
Medium size should be just small enough to go on a plane as hand luggage.

delightfully light, very comfortable, well ventilated
too big for cabin baggage, a bit inflexible for getting in a case

Super rucksack. The Osprey 48 is perfect for a weekend away in the hills. The curved back stops the rucksack from touching the centre of your back while in use. It is very comfortable and lightweight.
Would have liked a front access panel zip.
