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.
