Osprey Sirrus

With a 36-liter capacity and a recommended load range of 15 to 30 pounds, this pack is well-suited for lightweight overnight trips or long, gear-intensive day hikes. It features a lower compartment and multiple access points that make organizing overnight essentials much easier than a standard daypack.

The AirSpeed system uses a tensioned mesh back panel that creates a significant gap between your back and the pack body. This design allows for excellent airflow, which helps keep you cool and reduces sweat buildup during strenuous climbs in warm conditions.

Yes, the Sirrus 36 features an adjustable torso system that offers 4 inches of range. This allows you to fine-tune the fit to match your back length, ensuring the weight is distributed correctly across your hips and shoulders.

Yes, it includes a hidden vertical side zipper that lets you reach items in the main compartment without undoing the top lid. Additionally, there is a separate zippered lower compartment, which is ideal for storing a sleeping bag or items you need to grab quickly.

The included raincover is designed to provide reliable protection against rain and is made with PFC/PFAS-free DWR materials. While it is highly effective for most trail conditions, ensure it is properly cinched around the pack to prevent water from entering through the back panel area.

Yes, the pack is equipped with Osprey’s Stow-on-the-Go trekking pole attachment, which allows you to stash your poles quickly without taking the pack off. It also includes a single ice axe loop and front panel lash points for securing additional technical gear.
