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.

London Enthusiast
Super light-weight. Comfortable fit and weight distribution. Have carried 15k+ with no discomfort. Easy access rear mesh pouch is very handy for wet rain gear. Excellent pack.
Beware, the drive to strip out any excess weight means straps are thinner, and mesh pockets are less rugged. Managed to tear a mesh pouch on the side by grazing against grit stone in the Peaks on the first outing. Oh, and you need to buy a rain cover as one is not included.

Beccles Enthusiast
I spent a lot of time researching rucksacks having had several disappointing purchases previously. This bag is hard to beat when it comes to the space it provides at such a light weight... and most importantly, it is comfortable. It is very cheap when you look at others, even in the Osprey range, for the weight and features. My son owns one too now. Highly recommended, just get yourself sized and buy the correct back length version.
It is not waterproof, but then so many are not now. The addition of a lightweight waterproof stuff sack has still enabled me to knock a kilo off my pack weight with this bag.

Kilmacolm Enthusiast
Very light, but comfortable with a reasonably heavy load. Used for recent 2 day backpack trip & held all my gear, including tent.
No zip at bottom, I like to take sleeping bag etc out without pulling out top load.
