I have triplet boys that are10 now.  They love this bag.  I got them all these backpacks 2years ago.  2 broke zippers on them and the 3rd is still hanging in there.  One of my sons insisted on getting this same bag again.  I was pleasantly surprised that this backpack is now smaller.  When they were 8 years old the bags were way too big and now the smaller size is better suited for him.  I'm not sure if the broken zippers were from bad quality or just the wear and tear of being a kid.
