Osprey have totally re-designed their award winning Atmos pack with the revolutionary Anti Gravity suspended back system. A tensioned one piece mesh sheet completely moulds to your body, a bit like a hammock, from shoulders to hips and provides unsurpassed levels of breathability. Because the load is spread so effectively you can load the Atmos 50 right up and still feel incredibly comfortable. The usual pressure points on the shoulders and hips are completely eliminated by the suspended mesh and the pack seems to "float" on your body.

A constant air gap is maintained between the suspended mesh and the body of the pack allowing superb ventilation, even across the hips where traditionally heat would build up and cause hot spots and rubbing. To further increase the breathability the shoulder straps are made from Exoform perforated foam to allow heat to escape and maintain comfort.

The AntiGravity Suspended back system has complete adjustability and is available in two sizes with the sliding shoulder harness providing an additional 10cm of adjustment per size; there are two sprung webbing cam locks behind the adjuster that need to be released to slide the shoulder harness up and down. Osprey have also incorporated their Fit-on-the-Fly hipbelt which easily adjusts by using Velcro to get the padding in the correct position over your pelvis.

The Atmos AG is the perfect all weather trekking pack that works in all conditions and Osprey have packed in all their usual features to make using this superb pack easy and practical. The main compartment is easily divided to separate wet kit or to store a sleeping bag and extra storage is available from the twin stretch mesh side pockets, a stretch front stash pocket, twin zipped easy access front pockets, twin lid zipped pockets and hip belt pockets.

Another great feature is the removable top lid, if you want to strip the pack down or just dont need the extra storage you can remove the top lid completely and use the integrated "FlapJacket" cover to retain the weather resistance of the top closure.

This brilliant pack is aimed squarely at serious end users who demand the best load carrying comfort and breathability from a pack stuffed with features and weighing under 2.02kg.

The product I bought was competitively priced. The video demonstration of the product assisted me in my decision to purchase the item and was very informative, as it showed all of the features and the fit. I chose "click and collect" which was an efficient and quick process. I would definitely shop here again.
