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 24 is the go-to choice for those who prefer panel-loading organization on day hikes in wet or hot environments where staying dry and keeping your cool matter most. 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. KEY ATTRIBUTES: • AIRSPEED™ SUSPENSION: Incredibly comfortable and ventilated tensioned mesh backpanel with added adjustability for variations in torso length to provide fine-tuned customization fit for every hiker and backpacker. • SEAMLESS HIPBELT INTERFACE: Users can’t feel seams that don’t exist, and because there aren’t any on the Stratos/Sirrus updated hipbelt, 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 Osprey’s integrated and removable raincover that stows in its own pocket when the sun returns. Features: • Dual side compression straps • Stow-on-the-Go™ trekking pole attachment • Dual side stretch mesh pockets • Ice tool loop with bungee tie-off • Integrated raincover • Zippered hipbelt pockets • Internal hydration reservoir sleeve • Dual-zippered panel access to main compartment • Large top panel zippered slash pocket
