Built for long day hikes and lightweight overnights in the backcountry, the lidded Osprey Sirrus 36 Women's pack combines carrying comfort ventilation and organizational features to deliver lightweight technical performance.
Employing Osprey's Airspeed Suspension with a 3.5mm LightWire frame, the pack's tensioned mesh back panel provides flexible support and breathability to combat heat build-up between your back and the pack body. Both the hipbelt and harness straps are padded with die-cut foam and covered in mesh to enhance comfort and optimize fit. The hipbelt utilizes an ErgoPull closure that provides leverage when tightening so you get a snug fit and optimal load transfer. An adjustable sternum strap is equipped with a safety whistle for emergencies. Osprey's women's specific fit results in a packbag shape, harness, and hipbelt all designed to contour and be comfortable for a women's frame.
This pack has an internal volume of 2197 cubic inches, or 36 liters. The adaptable suspension system can adjust to fit torso lengths from 15" to 19", making this pack suitable for a wide range of users.
Under the fixed lid, a drawstring closure provides access to the main packbag. There's also a hidden vertical side zipper and a zippered lower compartment with a floating divider for additional access. A front zippered stash pocket, two side stretch pockets, and dual pockets on the pack's fixed lid offer additional organizational options. A fitted raincover is included for protection from the elements.
Other features include a Stow-on-the-Go trekking pole attachment, removable sleeping pad straps, side compression straps, an ice axe tool loop with a bungee tie-off, gear lash loops, and zippered hipbelt pockets. An internal sleeve and drinking tube pass-through make the pack hydration compatible (hydration system sold separately).
Constructed of bluesign approved recycled fabrics with a DWR finish, the Osprey Sirrus 36 Women's internal frame backpack is available in your choice of color options.
