Osprey Sirrus 36 women's trekking backpack

The Sirrus 36 by Osprey is a women's trekking backpack ideal for longer day hikes or short overnight trips, offering a perfect balance between load capacity and ventilated comfort. This top-loading model stands out for its AirSpeed suspension system, characterized by a mesh back stretched over a LightWire frame that ensures exceptional airflow and a fit specifically designed for the female anatomy, fully adjustable for torso length. Access to gear is facilitated by the top closure with a fixed hood featuring pockets and a practical separate lower compartment with a zip, perfect for a sleeping bag or for dividing the load. Organization is optimized thanks to the vertical front pocket, elastic side pockets, and zippered pockets on the hip belt. It is equipped with essential technical features such as the Stow-on-the-Go system for securing trekking poles without removing the backpack, removable straps for the sleeping pad, a loop for an ice axe, and an internal reservoir sleeve. It includes an integrated waterproof rain cover at the bottom and is made with durable 100% recycled honeycomb nylon approved by bluesign, with a PFAS-free DWR water-repellent treatment.
