    Hit the trail with everything you need.

    Get out for a weekend—or a week—with the Women's Sirrus 50 Backpack from Osprey Packs. This lightweight hauler features Osprey's AirSpeed ventilated suspension system to not only carry your load smoothly, but also help to keep your back cool so you can hike for longer under the hot summer sun.

    Top-load access makes it easy to stuff everything inside that you need, and a separate sleeping bag compartment allows for some on-trail organization. A removable floating top lid and removable sleeping bag straps allow for easy customization of your load. To keep you hydrated, Osprey included an internal reservoir sleeve, and, speaking of water, an integrated rain cover ensures that you don't end up at camp with a backpack full of soggy clothing. A variety of pockets and tool attachment systems, including the Stow-on-the-Go trekking pole attachments, lets you bring along exactly what you need for your journey.

    • Perfect pack for quick overnights or multi-day excursions
    • Tough nylon construction ensures durability
    • Ventilated suspension system carries your load smoothly
    • Mesh harness and hipbelt stabilizes the load with comfort
    • Integrated rain cover has your back in a rain storm
    • Ice axe and trekking pole attachments help free up hands
    • Sleeping pad straps and bag compartment free up room in bag
    • Osprey Packs are based out of Cortez, CO
    • Item #OSP007U

    Another gem in the Sirrus series

      I ordered this after receiving the Kyte 46 and deciding that it didn't live up to the smaller Sirrus pack I had. The fit of the 24L Sirrus is so perfect that I had to send the Kyte back to get the Sirrus50 and I'm glad I did. The frame features a molded and curved bottom where the pack sits on your hips which is super comfortable. Additionally, the tension mesh that keeps the pack off your back and allows for airflow is far superior to the airflow system that the Kyte pack had. I just recently did a steeeeep hike to a mountain lake in ~90 degree weather and stayed comfortable while my guy melted into a puddle with a lesser pack. Adjusting this to fit took a bit of doing because the torso length is adjustable with a velcro system that moves the straps up and down. I would suggest having someone help with getting the fit right and then using only the lower shoulder strap adjustments to get in and out of the pack once you get it right. The shoulder straps have a honeycomb type material that is definitely too scratchy on your skin to wear a tank top, so plan on wearing a top that covers you. If you're like me and your phone is also your camera, don't expect to fit your iphone in the waist belt pockets - at least not in the xs/sm size. I did find that I could easily slide it through the bottom slit in the water bottle holder and reach it while the pack is on without worrying that it would fall out. To maximize the space in this pack for backpacking, I would also suggest investing in a set of origami bowls and plates and sliding them down into the water bladder sleeve - then carry a water filter to fill up a bottle instead of sacrificing room for a hydration system, not to mention all that weight.
      Also - the ruska purple color is much more of a pomegranate/berry type color than the grape purple it looks like in the picture. Much preferable, actually

      I really like this pack for 2-3 day outings. The Sirrus24 has been so used and abused that it left me very confident in ordering the 50L version and I'm glad that I did.

      For reference I'm 5'1" 110lb. and got the xs/sm. I would expect that size to fit a girl slightly taller than I as well, like up to 5'4"ish
