Re: Most Durable Brand Bag
I kick the hell out of my Gateway backpack bag. I have a Blind Crow bag divider, which shrinks the bag about one disc and adds about a discs weight. It features metal and some super durable plastic, instead of PVC or injected molded junk. This keeps the bag in shape ( as hardly any of the marketed dividers actually help maintain the overall durability of the bag, what with sharp points and non-fiting parts ) and also makes it super resistent to soccer style penalty kicks and Olympic hammer throws.
They can be ordered through Iron Lion DGS. They are well worth the $25 for the investment of a $100+ bag.
