Large, light, strong and very comfortable - a pack that makes trekking less of a trial.

Osprey's ground-breaking Atmos AG Rucksack has been designed to keep you cool and comfortable if you're carrying a heavy load - fill it to the max and it’ll feel practically weightless on your back.

Their unique suspended AntiGravity™ backsystem, ExoForm™ Biostretch™ harness, load lifter bar and the Fit-on-the-Fly™ hipbelt all come together to make sure you're well ventilated and unburdened, even with a full pack of kit.

AntiGravity™ 3D suspended mesh backpanel/hipbelt - its seamless mesh and 3D cavity backpanel gives you unrivalled ventilation and comfort, with excellent load-carrying performance

FlapJacket™ top cover (for use when lid is removed) - provides protection, compression and extra head clearance

Stow-on-the-Go™ lets you stash your trekking poles quickly and conveniently without removing your pack

Fit-on-the-Fly™ adjustable hook and loop hipbelt - lets you adapt the pack to your size, to give you the best fit

InsideOut™ compression provides impressive load support, reducing fatigue so you can push your adventures harder and longer.

Add to all that the Atmos Ag's multiple entry points, Stow-on-the-Go™ trekking pole attachment, large sleeping bag base compartment and the (integrated, detachable) raincover in the (removeable) lid and you've got a pack that will serve you well whatever your journey.

“The Atmos’s new AG suspension system throws conventional pack design out the window with stellar results. This pack raises the bar for big-load ventilation.” Backpacker Magazine February 2015

“The back system raises the standard for comfort and stability with heavy loads” Trail Magazine April 2015

If you are unable to use Osprey's pack sizing app, then measure yourself by following these steps:

1. Locate your C7 vertebrae  (the bony bump at the base of your neck, where the slope of your shoulder meets your neck) - tilt your head forward to locate it more easily

2. Place your hands on the very top of your hips so you can feel your iliac crest, which creates your ""hip shelf""

3. Measure the length between the C7 vertebrae and the iliac crest, making sure to follow the contours of your spine.

Based on your measurement, select the size which you best fall into:

Outstanding!, 17 April 2016
By Electric Monk (Essex)
Recently upgraded from a 20 year old pack, and have been very impressed. So far I've trekked about 50 miles with this fully loaded (c17kg), and cannot fault it. It feels like carrying less than half the load, and all the weight goes through your hips; the shoulder straps feel optional (don't recommend trying this though).
It takes a little while to fully adjust for maximum comfort, but is time well spent.
The hip pockets are useful, and you can comfortably stash two 1l water bottles in the lower side mesh pockets. There is a technique to getting them back in, but when mastered is easy to drink while moving.
The stow-on-the-fly pole loops are also useful.
This is twice what I would normally spend on a pack, but it is without a doubt the most comfortable rucksack I have owned.
