The Osprey Sirrus 24 uses a fully adjustable AirSpeed™ ventilated back system, combining the single piece construction of the backpanel and hipbelt with highly breathable suspended mesh to give you increased comfort in warm weather, even with a heavy load.

Tailored with a women's specific fit, it has an ergonomically shaped hipbelt, harness, yoke and backpanel.

The detachable raincover (stored in the bottom pocket) increases weather resistance and tough nylon fabrics ensure durability. The large panel opening, easy access pocket on the top and a large, vertically zipped expansion pocket on the front give lots of easy access options.
