Sirrus 44L Backpack

The largest of the Sirrus packs, the Osprey Sirrus 44L backpack features a highly ventilated back panel and a full set of hiker-friendly features. The Airspeed mesh suspension system maximizes ventilation and includes a ladder adjustment system to adjust the torso length up to four inches. The 44-liter capacity is best for short trips, but it's still long on features with an included rain cover, trekking pole and ice axe attachments, accessory straps for a sleeping pad, and plenty of pockets, including hip-belt pockets to get at small essentials without breaking stride. The Sirrus is a serious pack for a hut-to-hut trek, a supported backpacking trip, or a fast-and-light overnighter.
