The men’s Stratos and women’s Sirrus hiking packs are some of the best-selling daypacks in the Osprey range. And we aren’t ashamed to say that we too have become dedicated converts, with the Sirrus and Stratos taking our Gear of the Year prize as the best hiking pack of 2024.

So what’s all the fuss about? Comfort is so key for a rucksack, and thanks to a full-perimeter wire frame and a plush, contoured harness, the Stratos and Sirrus carry extremely well. A suspension back system ensures ventilation is superb, while being fully adjustable for the perfect fit.

As you’d expect from Osprey, they’re also well-featured, with front, side, and hipbelt pockets, as well as inner and outer lid pockets. The front shove pocket is made from abrasion-resistant fabric rather than flimsy mesh and is accessed via a centre zip.

The pack is also fully kitted out with a hydration sleeve, trekking pole loops, pull-out raincover and dual side compression straps. You get plenty of other attachment points too, including Osprey’s ‘stow on the go’ loop for temporarily holding your trekking poles.

For hillwalking, it really does tick all the boxes, and being sustainably made from 100% recycled materials, it is a worthy winner of our Rucksack Gear of the Year accolade.

Why the Osprey Stratos/Sirrus 26 won Gear of the Year 2024


Osprey Stratos front view

Osprey was one of the first pack makers to develop gender-specific fits for men and women. So, compared to the men’s Stratos, the Sirrus has contoured shoulder straps to accommodate most women’s neck, shoulders and chest.

The hipbelt is also designed to wrap naturally around the curves of female hips. And the torso length is shorter too. But in addition, both the Sirrus and Stratos have easy-to-adjust five-point back systems that make it a cinch to get a perfect fit.

The Sirrus and Stratos rucksacks both feature Osprey’s excellent AirSpeed suspended mesh back system, which delivers very welcome airflow to stave off stickiness on hot and humid hill days.

A trampoline-style panel keeps the bulk of the pack away from your back, allowing plenty of ventilation. It’s superior to simple foam back panels and is a built-in feature that we’ve really come to appreciate, particularly when heading remorselessly uphill in warm weather.

The Sirrus and Stratos 26 are classic toploaders with double-buckle lids – the ideal configuration for a hillwalking pack. We much prefer it to most top-zippered designs, as the lid can be cinched down or raised, depending on the load.

It also has a zipped access lower compartment with a floating liner, which helps keep contents organised and accessible. And size-wise, it comes in various sizes, but 26 litres hits the sweet spot for a summer hiking daypack.
