A bag for long use and heavy loads.

The Osprey Sirrus 36 ensures that you’re comfortable as possible on demanding trails and long hikes.

Its single piece backpanel and hipbelt allow you to benefit not only from fantastic weight distribution and stability, but from the ventilation that comes with their highly breathable mesh construction. With a women’s specific fit, an ergonomic hipbelt, harness, yoke and backpanel, the bag offers exceptional comfort, even with heavy loads.

The practicality of the Sirrus 36 extends far further than its breathability and support, however. Each feature is competently designed to improve the hiking experience. 

The high capacity main compartment is easily accessed with the side zip, so you don’t have to open the lid each time, and the base of the pack has a separate sleeping bag compartment – drastically simplifying your nights and mornings alike. 

There is even a bellowed divider to keep things even more ordered, and when you’re all packed up and ready to go, you can quickly stabilize and compress the whole lot with the side compression straps.

If it rains, there’s a detachable raincover that will quickly dismiss it, and when the temperature rises you can stash your extra layers in the front expansion pocket.  

There are further considerations for a great deal of things included here; ice axe, trekking pole and key holders and are just a few handy additions.

If you’re serious about your hiking, then you’ll need a serious backpack: the Sirrus 36 is the solution you need to go further, for longer.

Osprey women's Sirius 36 rucksack

The backpack is great for long hikes and heavy stuff. It's super lightweight and fits great - snug around the body in a way that just made it feel like an extension of my own.. So yeah definitely 5 stars from me
