The OspreyExos Pro 55 pack offers comfort and ventilation in an ultralight package, perfect for multi-day backpacking. Built with a weight-conscious ethos, the 55-litre model includes strippable features such as the top lid to save grams without compromising functionality.
The feature-rich design includes a FlapJacket cover for lidless use, which protects access to the main compartment. Inside, you'll find a hydration bladder sleeve with an OspreyHydraclip for secure storage. External lash points, a front stash pocket, and dual-access side pockets all aid with gear organisation.
Constructed with an AirSpeed tensioned mesh back panel and LightWire frame, the Exos Pro delivers the comfort and support needed when carrying a full pack. Torso-length adjustment enables a precise fit. Internal and external compression straps help to stabilise the load. Well set for long-distance trails, Osprey's pack-making expertise shines through in this backpacking model.

PFC-Free
Per- and polyfluorinated chemicals (PFCs) are a family of human-made, fluorine-containing chemicals. They have long been used to add water and stain repellent properties to technical fabrics. PFCs can harm the wearer of the garment and damage nature. Incredibly resistant to breakdown, these pollutants have been found across the globe; they can remain in the environment for many years after release. In response, a growing number of PFC-Free products are being developed, designed to provide reliable water repellency without the use of these harmful chemicals.
Recycled
Patagonia first made a fleece from recycled plastic bottles in 1993, since then more and more brands have been ‘recycling rubbish’ to make the high-performance clothing and equipment that we all love to rely on in the outdoors. There are now many different types of materials and products made from waste that would have otherwise ended up in a landfill.
