We use 5 gallon buckets with screw on lids..You can buy the buckets at Lowes hardware, there around 3 or 4 dollars each, and the lids you can buy at sears in the hardware stuff, There called gamma seal lids. They snap on the bucket and the center screw's out.. There pretty reasonable, We got each boy two, They will hold all of their personal gear, and enough air stays in them so they will float. Just in case. They are lo -profile in the boat and take up less space.
