Inspired by Osprey's AntiGravity™ technology, the Sirrus 36 pack features a fully adjustable AirSpeed™ back system, which combines the integrated construction of the back panel and hip belt with a highly breathable suspended mesh.
This concept helps increase comfort in warm weather, even when carrying heavier loads. The Sirrus 36's carrying system features a specific women's fit, with an ergonomic hip belt, shoulder straps, crossbar, and back panel.
The clean, classic design, combined with outstanding wearing comfort, makes the Sirrus 36 one of the top choices for walkers and hikers looking for a well-ventilated daypack with enough space for lightweight camping and sleeping equipment, or extra layers of clothing when the weather is changeable.
The removable rain cover, made from durable nylon, stows in a pocket located at the bottom of the pack. The Sirrus 36 features a lid with dual clip closure and drawstring, a large easy-access pocket in the lid, and a front zip expansion pocket, ideal for storing a jacket or spare clothing.
The side of the pack is fitted with a vertical zip that allows direct access to the main compartment, eliminating the need to open the lid. A zip sleeping bag compartment is available at the bottom, with a divider system for optimal load distribution. The pack is suited for long days out or easy multi-day trips in warm weather.
The Sirrus 36 is compatible with all Hydraulics™ and Hydraulics LT™ reservoirs, features a waterproof cover with DWR treatment, and is made from Bluesign® certified materials.
