Every year me and a group of guys float the Buffalo River in Arkansas. While the river isn't usually all that bad, there is no such thing as keeping water out of the boat. This year I picked up a pack of Exped's dry bags to help myself and others on the trip keep essential gear dry. We made the float in great shape along with all important gear! Not only was the gear dry, there was no danger the bag and it's contents would leave the boat unexpectedly. I've snagged one of the smaller bags to keep in my backpack for everyday use as well.
