Osprey Atmos 50 2011

Osprey has rapidly developed itself as a brand that provides excellent, comfortable and well-designed rucksacks, and the Atmos 50 is a good example of this.
Many Osprey sacks feature the Airspeed breathable back panel, which holds the sack away from the body for great airflow. You also get perforated padding on the shoulder straps and hipbelt to make the sack feel even less sweaty.
The body has stretch wand pockets, a stretch front stash pocket and two more front-zipped pockets, so it’s great if you like to divide up your kit so you can find it in a hurry. It also features a hydration pocket for a water bladder.
My only real niggle is the floating lid, as the sides can drop forward if the lid has something heavy in it and the body is half empty – the result being water can get into the body of the sack.
I love the Osprey Atmos 50’s large lid pocket, though, and the comfort, general design and performance are great. Quick-release compression straps would be a good addition.

The Osprey Atmos 50 offers superb comfort from the Airspeed back system and lots of great features, but the lid is not the best design around.
