After exhaustive research, I picked this pack to take with me for my Peace Corps service In Ethiopia. I've been using it daily here in the States to get to know it, and I am so so happy with my choice. I love the separate "laptop" section for all my notebooks & my laptop. All my other bulky stuff goes in the other full size section. The helmet pouch is where I put my keys, or the first aid kit I carried around as the camp nurse. Highly recommend.
