Osprey Womens Sirrus 44 Rucksack

Jump to: Our Verdict / Features / Specifications

Osprey’s Womens Sirrus 44 Rucksack is a durable and comfortable backpacking rucksack with a full feature set including a front zip access to the main compartment.

Osprey says

You take your hiking seriously, and like to stretch your day hikes into lightweight overnights more often than not. The Sirrus 44 is a full-featured women’s-specific pack built for rugged trails, rain or shine, with serious features and a top-loading design so you can easily stuff and go. It’s a technical pack with a cloud-like carry, thanks to its highly ventilated AirSpeed suspension system. Made with 100% recycled materials.

Our Verdict

Osprey’s Sirrus 44 Rucksack is not an ultralight product but it’s a really solid rucksack that is durable with a full feature set and a decent fully adjustable harness with vented back. The hip fins wrap well around the hips and the weight transfer is good, so this is a good solid choice, at 44 litres its a good capacity for backpacking trips where this level of durability is important.
