Atmos AG 65L Backpack

It's simple: the comfier the backpack, the comfier the hike, and the comfiest backpack is the one that fits best. The Atmos AG 65 Backpack is Osprey's best-fitting, most ventilated, and comfiest option for multi-day treks. Multiple adjustments running vertically and horizontally place the padded shoulder straps and suspended mesh back panel right where we want them, and the padded Fit-on-the-Fly waist belt lets us buckle, cinch, and go without hassling with a bunch of micro-adjustments.
