Osprey Atmos AG Backpack

The Anti-Gravity system uses a continuous panel of lightweight mesh that extends from the top of the back panel to the hip belt. This creates a trampoline-like effect that keeps the pack off your back, providing exceptional ventilation and distributing weight so evenly that the pack feels like it is hugging your body rather than sitting on top of it.

Yes, the Atmos AG features an adjustable torso length system. You can easily slide the harness up or down along the back panel to dial in a precise fit for your specific back length, which is crucial for transferring weight properly to your hips.

The Fit-On-The-Fly waist belt allows you to extend the padding on the hip belt by several inches. You simply pull the tabs to adjust the length while wearing the pack, ensuring you get a secure, customized wrap around your iliac crest without needing to take the bag off.

With a 65-liter capacity, this pack is specifically designed for multi-day trekking and week-long excursions. It offers enough volume for a sleeping bag, tent, cooking system, and several days of food, provided you pack efficiently.

Yes, it includes an integrated rain cover that is stored in its own dedicated pocket. It is designed to deploy quickly during sudden storms to keep your gear dry.

The pack features Osprey’s Stow-on-the-Go system, which consists of two elasticized loops on the side of the pack. This allows you to quickly stash your trekking poles without taking the backpack off, which is ideal for sections of the trail where you need your hands free.
