Osprey S/M Sirrus 36 Hiking Backpack Bag, Black

The supremely ventilated, featured and durable Sirrus Series receives a makeover that is more than skin deep for Spring 2017. Now featuring adjustable torso lengths, improved women's specific fit and comfort with updated aesthetics, the Sirrus 36 is the go-to choice for everything from short day hikes to lightweight overnights in the backcountry no matter how far, or near. When the weather turns, fear not Sirrus keeps your gear and pack protected with an integrated raincover. Smartly organized pocketing keeps all your equipment where you need it, when you need. Airspeed Suspension Incredibly comfortable and ventilated tensioned mesh back panel with added adjustability for variations in torso length to provide fine-tuned customization fit for every hiker and backpacker. Seamless Hip belt Interface Users can't feel seams that don't exist, and because there aren't any on the Stratus/Sirrus updated hip belt, hikers can focus on the journey instead of the pack on your back. Integrated Raincover Hope for bluebird weather but know you're covered with our integrated and removable raincover that stows in its own pocket when the sun returns. Additional Features Dual side compression straps Stow-on-the-Go trekking pole attachment Ice tool loop with bungee tie-off Internal hydration reservoir sleeve Fixed top-lid with zippered slash pocket Front panel vertical centre zippered pocket
