Congrats ! Those are really neat.
I looked at them before buying some Shimano ice chests. The Shimanos are soft sided with drysuit zippers. you can fill them with water and turn them over with no problem. I thought I might use mine with water in them ( bait ) and didn't need the dividers or interior velcro, so I just went with the ice chests. They finally evolved into my camera and electronic gear bags.
