Know before you buy
The pack is designed to carry a load range between 25 and 35 pounds (11 to 16 kg). Staying within this range ensures the AntiGravity suspension system functions as intended for maximum comfort.
Unlike traditional foam padding, the AntiGravity system uses a continuous panel of lightweight mesh that extends from the top of the back panel to the hipbelt. This design contours to your body, providing superior ventilation and distributing weight so the pack feels lighter on your back.
Yes, the Atmos AG 50 features a Fit-on-the-Fly harness and hipbelt. These components are adjustable, allowing you to fine-tune the torso length and hipbelt position for a custom fit that matches your specific body shape.
The pack comes with an integrated, PFC/PFAS-free raincover included. It is stored in its own dedicated compartment, so you are prepared for unexpected weather without needing to purchase extra gear.
Yes, it features an internal hydration reservoir sleeve with a center back exit port. This allows you to easily route your hydration hose over either shoulder for convenient access while hiking.
You can access the main compartment through the top lid or via the curved zippered panels on both sides of the pack. These side zippers make it much easier to reach items buried in the middle or bottom of your pack without unpacking everything.
