Osprey Atmos AG 50 is an ideal trekking backpack for multi-day outings in the outdoors, which thanks to its technical characteristics allows you to carry everything you need with you with maximum comfort and ventilation. The AntiGravity backrest offers a fit that defies the laws of physics and wraps the back and hips continuously in a suspended three-dimensional net. This allows you to distribute the weight super efficiently giving you the feeling of carrying a backpack that is lighter than it actually is. The shoulder straps and the waist belt are made with Fit-on-the-Fly technology that allows for an adjustment and therefore an exceptional fit and comfort. Made from 210D Nylon Honey Comb it is durable and super resistant to tearing and abrasion. In addition, in case of rain and bad weather you can use the integrated cover with DWR treatment. If you want to reduce the weight of the backpack, you can remove the hood and use the FlapJacket cover. Load organization is also at the highest level: the bottles fit neatly into the external side pockets, the internal hydration bladder pocket gives you more options for hydration and the Stow-On-The-Go attachment for poles trekking equipment allows you to store your equipment when you need to have both hands free. You'll also have ample access to the main compartment via a curved zipper on both sides. There are also several compression straps to allow you to attach the equipment you want to have on hand, otherwise you can use the handy zippered pockets present in the waist belt.
