This backpack has far exceeded my expectations on all levels. I have a very active boy who uses this bag daily and after a few months of use it still looks like new.  The material is strong and durable, not that stiff cheap stuff that wears out or tears after a little while. The four pockets are all very useful and roomy. Plenty of clips and little pouches to carry extras and the adjustable cinch-down straps across the sides make it easy to get a snug fit to eliminate jostling. I love the stretchy shock absorbing parts on the straps. We are still amazed at the amount of items you can easily fit inside this bag. My little guy can easily get the bag on and off on his own and the straps can adjust to properly fit him or myself and anyone in between and Bonus-- you don't look like a turtle. The best part is the stellar quality of the zippers on the bag. All are nice, big and sturdy making it easy to open and close without snagging or separating. All around Aces Ten for this bag.
