I purchased a Throwback All Day Pack because I wanted a disc backpack that also had a built in cooler. This can hold 6 side pockets that can hold 3 discs each (or 2 putters) plus a front pocket that can hold the same. The big center portion is a cooler than can easily hold a 6-pack plus ice packs. A 12-pack could fit, but things start getting pretty heavy. So, I ended up getting me a 3 wheeled push golf cart. This thing has an included umbrella holder, cup holder, and built-in stool! The backpack can be bungied to it pretty easily, but kinda flops around some, so I used 2x2s and a small piece of plywood to build a shelf for the backpack to sit on for stability. Let me know what y'all think!
