This backpack is huge, very well made, waterproof, and perfect for anything outdoor. I got this for an upcoming camping trip and then I will use it for a survival kit. The top rolls down and secures to keep water out of the top. The straps are rather comfortable and well made. The only thing that would make this better is if there were pockets inside of it to help me organize the inside a bit better. But I am extremely happy with the way it is.
