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 that not only carries your load smoothly, it also helps to keep your back cool, letting you 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. Compression straps help secure the load if you're not heading out for as long.
