Review: Osprey Exos/Eja 48L pack

Back in the day, the words ‘multi-day pack’ would have conjured images of staggering along beneath the weight of a 100-litre behemoth, with pots, pans and a tin mug clattering together on the outside.

Thankfully, those days are largely behind us. Modern outdoor equipment is considerably lighter and more compact, meaning a week-long hiking trip can often be tackled with a pack of 60 litres or less.

One of Osprey’s longstanding favourites, the Exos (or Eja for women – an approximation of the pronunciation of ella, or ‘her’ in Spanish, fact fans), is the brand’s bluesign-approved ultralight hiking pack ($429). But lightweight doesn’t mean compromising on the features that make a pack comfortable and practical over long distances.

At the heart of the Exos is Osprey’s ExoForm harness and hipbelt, featuring adjustable components and breathable mesh to provide a comfortable, supportive fit. The Airspeed suspension system is another standout, using a tensioned mesh back panel to create space between your back and the pack. This promotes airflow, helping reduce heat and sweat build-up on demanding climbs and warmer days. Think of it as a little personal ventilation system.

Storage is equally impressive. Seven pockets provide plenty of options for organising essentials, from snacks and maps to water bottles and smaller accessories. Multiple attachment points and straps offer additional flexibility for carrying gear externally, while the clever FlapJacket system provides cover and security when using the pack without its top lid.

The result is a pack that balances low weight with comfort, ventilation and clever storage solutions. It’s easy to see why the Exos and Eja have developed such a loyal following among long-distance hikers.
