Osprey Sirrus 44 Women's Backpack

You take your hiking seriously and like to stretch your day hikes into lightweight overnights more often than not. The Sirrus 44 is a full-featured Women's-specific pack built for rugged trails, rain or shine, with serious features and a top-loading design so you can easily stuff and go. It's a technical pack with a cloud-like carry, thanks to its highly ventilated AirSpeed Suspension system. Made with 100% recycled materials.

Designed for all-day comfort when hiking in the hills, the Sirrus 44 features a fully adjustable AirSpeed ventilated back system whilst still giving enough room for spare clothing, food and the essential kit. Constructed using tough, durable Nylon fabrics, the backpack is built to last. As well as this, a rain cover that is included with the pack is ideal for when you get caught out in heavier rain. This fabric, although thick and durable, is very lightweight so that you barely feel like you are wearing the pack.

An AirSpeed suspension system works to excellently transfer weight for a more comfortable and lightweight feel. This injection-moulded suspension system with 3D-tensioned mesh provides superior ventilation even on the hottest hikes so that you can remain comfortable throughout the warm days. The hip belt and shoulder straps feature a die-cut foam reinforcement to provide stability, support and ventilation that flex beautifully around your body for increased comfort. The hip belt is teamed with a built-in, adjustable sternum strap to help spread the load by transferring it to these areas and away from your shoulders. Taller, wider frame geometry combines with a tailored adjustment system to extend the fit range for additional support and comfort.

The Sirrus 44 features a fixed top lid with a large main compartment and an under-lid zipped mesh pocket with a key clip that ensures unhindered access and easy entry for the contents of the pack. Hidden vertical side zip access into the main compartment offers even quicker access to contents. A hydration sleeve and a little clip to prevent the bladder from drooping down to the sleeve feature in this main compartment. A hose port in the back panel allows for quick and easy hydration. The pack provides storage for your trekking poles and ice axe with loops and attachment systems on the outside allowing you to stash them away safely and efficiently whilst keeping the pack on. The Stow-on-the-Go trekking pole attachment features a new soft-touch tube. The Sirrus 44 also features a hidden vertical zipper on the left side of the pack that accesses a large pocket for additional storage, two stretch mesh side pockets large enough to hold an insulating layer or a bottle, and dual zipped pockets on the hip belt. As well as this zipped access to the lower compartment with a floating liner keeps contents organised and accessible while accessory straps on the lower front panel are perfect for pads or blankets. Lastly, dual-sided compression straps pull the weight closer to your back to increase comfort and carrying efficiency. These straps also prevent your gear from moving about when the pack is not full and can be used inside or outside of the side pockets depending on your need.
