Osprey presents its new trekking backpack, the Back.Atmos AG 50 Venturi Blue.
The AG AntiGravity™ system - the main feature that made the Atmos 50 AG famous - offers you a fully ventilated back panel as well as a fully ventilated waistband. The seamless mesh and 3D cavity back panel offers unparalleled ventilation and comfort!
Each of the adjustment elements allows you to perfectly fit your backpack to your body shape. The Fit-on-the-Fly™ belt and the ExoForm™/Biostretch™ harness ensure easy handling of your bag, even with a heavy load.
This bag is renowned for its practicality thanks to its different loading access points: access to the bottom of the bag, access from the top. In addition, the loops for attaching hiking poles are accessible while on-the-go, without having to remove your bag.
Ready to tackle all weather conditions, it's also ready for the rain with its integrated removable waterproof cover. Equipped with the InsideOut™ compression system, the Atmos AG 50 reduces the fatigue experienced when carrying heavy loads as it is extremely comfortable.
Lightweight, practical and well thought out, theAtmos AG 50 East is ready to accompany you on your outings and expeditions.
