This video we review the Osprey Atmos AG 65 liter backpack. This is the biggest backpack I own and have used on the trails. I use this one when I am spending one or more nights in the mountains. This is a great backpack with lots of features. I hope this gear review gives you more insight on what this backpack has to offer when considering which one to purchase for your own adventures. May God bless you in your mountain adventures.
