Ventilated comfort for loaded day walks
Osprey says:
The Sirrus Series are full-featured hiking packs that offer durable, high tenacity nylon that offers outstanding performance in a rugged, traditional design. A molded ladder torso adjustment system dials in comfort and a tensioned mesh AirSpeed backpanel offers premium breathability. A new molded ladder design this season dials in the fit while updated shoulder straps expand the fit range.
AIRSPEED VENTILATION - A tensioned-mesh backpanel keeps the weight off your back, enabling highly ventilated carrying comfort.
COMPREHENSIVE FIT - A molded ladder torso adjustment system and updated shoulder strap design dials in the optimal fit and expands the fit range
INCLUDED RAINCOVER - Keeps pack and gear dry in inclement weather.
Our Verdict
At 1238g, the Osprey Women’s Sirrus 24 is a supportive daypack for longer hill walks. The AirSpeed back system is the main strength, holding the pack away from your back to improve airflow on warm climbs and long days.
The women ’s-specific fit uses a shorter 38–50cm torso range, with a shaped harness, padded hipbelt, and load lifters to help dial in the carry when the pack is loaded with water, layers, and food.
Organisation is strong, with panel access, hipbelt pockets, side pockets, a top pocket, and an included rain cover. It is not a lightweight daypack, but it works well for walkers who value ventilation, comfort, support and on-hand storage.
