Inspired by Osprey’s AntiGravity technology the Women's Sirrus 36 is shaped for female bodies and has a fully adjustable AirSpeed, trampoline suspended mesh back system, which combines the single piece construction of the backpanel and hipbelt with highly breathable suspended mesh. The torso length can also be adjusted, all of which allows for increased comfort in warm weather, even with a heavy load.
There are multiple entries to the large main compartment including a zipped base which facilitates easy access to your belongings. A frontal vertical zipped pocket is perfect for packing a map or some snacks separate from your other gear. Further storage is provided via stretch mesh side pockets, a vertical zipped front pocket, and two zipped hip belt pockets that are ideal for valuables.
There's also an internal key attachment clip which keeps your key safe and handily placed, so there's no need to rummage around in the pocket. There is also an outer pocket containing an integrated and detachable raincover which can be stretched over the pack. External hydration access is available, with a handy clip so the (up to 3L) reservior does not slip down your back. All of this storage can be thoughtfully compressed using side cinching.
A sleeping bag base compartment with internal divider sits at the base, and is ideal for any multi-day expedition. Further hiking specifications include the Stow-on-the-Go trekking pole attachment, which allows you to tuck your pole away so your hands are free to map read, while an ice axe loop sits towards the base of the pack. The Stratos is ideal for weekend adventures with friends as well as day trips with the family.
