Wearing the AG65 from Osprey feels like getting a big hug which is not something you can say very often when talking about a backpack. The 'AntiGravity' back panel keeps the pack well clear of your back making for great ventilation, the mesh lined shoulder straps and hip belt do just as impressive a job of both bearing the load and keeping you ventilated.
The straps are quite burly and thickly padded which adds to the not inconsiderable weight of just under 2.2kg but the comfort level when carrying a heavy load is seriously impressive.
The hip belts are adjustable with a simple but effective Velcro fastening system, the shoulder straps are a bit of a faf with access to the cam release mechanism being just behind the mesh back panel but the range of adjustment afforded should allow most to get a good fit.
The range and usefulness of the pockets on the AG65 is also very impressive, the hip belt and side pockets are oversized which makes grabbing and re-packing essential items on the move easy and fuss free. The stretch mesh side pockets are angled in just the right way and provide further useful storage options.
The AG65 comes with a removable floating top lid as well as a 'FlapJacket' top cover, we chose to remove the floating lid to shave a few hundred grams from the overall weight. The rain cover is integrated but can be removed to save further weight if you're expecting fair weather (can we ever take that risk in the UK?!).
The main compartment includes a compression strap to secure the load internally, this works well in conjunction with the external compression straps and makes for a rock steady load which doesn't shift around even on tough terrain. The bottom sleeping bag compartment can be accessed by a separate zip to save you the hassle of emptying your whole bag to get to it, which you would otherwise have to do thanks to the lack of front or side access to the main compartment, about the only criticism we have of this bag.
The Atmos AG65 comes with a hefty price tag but head out into the hills fully loaded and you'll be patting yourself on the back for making such a solid buying decision.
