Product Description Item No.   10270415

The Osprey Women's Sirrus 50 Pack is a ventilated backpack for overnight to weeklong trips into the backcountry. The Sirrus begins with the Airspeed™ suspension, combining a LightWire™ alloy frame with a 3D tensioned mesh backpanel and a spacer mesh harness and hipbelt to secure the pack to your back. The smooth fit wraps your back and shoulders and vents to allow your body to breath along the way, even when loaded up with gear for the week. The top pocket is removable in case you want to lighten the load and the lower zippered compartment houses your sleeping bag separately from the rest of your stuff. Strap an ice axe to the pack via the ice axe loop and utilize the Stow-On-The-Go™ trekking pole attachments for hands-free hiking. The integrated raincover keeps your gear on the inside dry in sudden storms.

Products on Sale are Discontinued Styles or Colors.

Osprey Airspeed

Osprey Airspeed
Using peripheral suspension design this lightweight, three dimensional suspension eliminates foam and backpanel materials and replaces it with lightweight suspended mesh. Three dimensionally shaped to allow maximum airflow and optimal tension and load carry sets Osprey apart from other tensioned mesh backpacks.

Osprey Peripheral Frame

Osprey Peripheral Frame
Peripheral frame was a departure from the norm many years ago and it’s still the foundation of our gear hauling packs. A wire frame runs along the outside of the backpanel directly connecting the upper load lifters and the central core of the pack to the hipbelt to transition and spread the load. Allowing natural torsional movement, effective adjustable torsos, and different load range and backpanel builds makes this suspension design truly innovative.

OSPREY MEASUREMENT GUIDE

Please note that the info provided above refers to the torso size each pack will fit, and NOT any dimensions of the pack. Below are some steps for how to get your torso length. You should probably have someone help take this measurement for you so it is accurate. And they might accidentally touch your butt.

HOW TO MEASURE TORSO LENGTH:
• Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt.
• From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down.
• Make sure you keep your back as straight as possible while measuring.
• This torso measurement determines what size Osprey pack you should carry. Refer to the size charts above to find your ideal size.
• If you are in between sizes, it is ideal to try them both on before ordering.

HOW TO MEASURE HIPBELT SIZE:
• Measure around your hips at your iliac crest, NOT your waist.
• A properly fitted hipbelt rides centered over the hipbones and needs to be very snug.
• The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the both hip pads when securely tightened.
• Refer to the Hipbelts size chart above to help determine your ideal Osprey pack size, but again, your torso length is what should determine your pack size, NOT the hipbelt.

Rated 4 out of 5 by from Great backpack! I usually don't post reviews, but this bag doesn't have one yet and it desperately needs it because I love this backpack! Spent a couple days picking out the one I wanted (between size, comfort, etc.) and then used it for three weeks backpacking through Europe. Strategic storage compartments make this really easy to pack in more than you think, and the adjustable straps are great to make the bag much smaller (I now use this as a carry-on bag for many flights). Both the adjustable waist belt and torso height really come in handy when you start to get tired because it allows you to fit the pack to your body, and I now swear by the mesh back panel.

Rated 3 out of 5 by from Disappointed in this pack I bought this pack to take to Europe backpacking. My fiance has a 48L and after we packed his we figured a 50L would be okay. His 48L held a significant amount more than my 50L Sirrus pack. I don't know if it is the shape of the frame or what it is but I was super disappointed when I received the pack and put it next to his for size comparison. It will get used some day but for now it will sit in my closet.

Is the sirrus womans 50 hydro compatible?

Asked by: Jim61
Hey there, Thanks for the question. This bag does have an internal reservoir sleeve, making it hydration compatible. I hope this helps!
