The Osprey Eja Pro 55 is an ultralight backpacking model offering comfort and ventilation to counter long days on the trail. A women's specific pack with an adjustable torso length, it's easy to achieve a perfect fit. An AirSpeed tensioned mesh back panel enhances breathability, and the LightWire frame increases support. Secure on the body, you can use the compression straps to further stabilise the load.
Practical and versatile, the Eja Pro includes strippable features like the top lid - take it off to shed 74 grams. In lidless mode, the FlapJacket cover protects the main compartment. Inside, you'll find a hydration bladder sleeve with an OspreyHydraclip for secure storage. The external front pocket, stretch side pockets, and webbing lash points are ideal for quickly stashing and accessing gear on the go. An excellent choice for multi-day tours, 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.
