i found some "boat bags" on sale at gander a few years ago. basically a duffel bag that has a pretty rigid bottom and its plasticoated/vynal so they are waterproof. we actually replace our roll top food bag with one of these and the tents fit in the other. the shoulder strap has clips so it can strap to a crossbar in the canoe and they are much easier to carry than the standard roll top bag being that they have a shoulder strap, 2 large handles and two smaller side handles. weve found them to be very useful.
