Inspired by the Osprey AntiGravityTM technology, Stratos and Sirrus offer a fully adjustable and ventilated AirSpeedTM back panel designed thanks to a mesh suspended in one piece from the waistband to the top of the bag. This provides better comfort even in hot weather with a heavy load on the back. The Sirrus backpack's back panel offers studied ergonomics specific to women, as well as adapted hip belts and shoulder straps.
Their classic style and sleek design combined with incredible carrying comfort make the Stratos and Sirrus the new essential companion for the hiker. The removable rain cover that fits into the bottom of the bag and the high quality Nylon used increase the resistance of the bag in all weathers and over time.
Stratos & Sirrus are ideal backpacks for long days of walking on winding trails, especially in warm weather.
