Comments about OSPREY Atmos 50 Backpack:

This is one of the most stylish, practical, and functional bags Osprey offers. it has a metal spine, which evenly distributes the load across your shoulders and hips and protects your lower back from excess weight. Unfortunately this metal spine is also the bags greatest flaw. The spine digs into your hips under any load greater than 25lbs and is more than a thorn in your side after the 4th mile. As much as I loved the style and practicality of this pack, it is far too uncomfortable to wear on extended hikes and I would NEVER consider using it for overnight camping.

Comments about OSPREY Atmos 50 Backpack:

This was/is my first pack. im a young adventurer so i havent had the experiance that i admire from the "profesionals". the pack fits plenty on the inside, all that i need and more. my tent straps to the oh so hady straps all along the front and sides of the pack. one great thing about this pack is it survives torretial rain and keeps its contents dry. the "blatter holder" is a wonderful feture however it kind of takes up too much room on the inside. the frame is comfortable and and sturdy. when the pack is on and packed full, it is very easy to manuver in. weight is easily distributed and the pockets on the hip straps are very convenient. all together an a+ pack. i cant give it five stars because nothing is perfect
