Here's what other sites are saying:
Your gear stays dry and visible in the Gaia See Turtle Deck Bag when you hit the water for extended adventures. A four-buckle attachment system secures the bag to the deck of your touring or recreational kayak. Down rapids, across lakes, and along the coast, enjoy the adventure and don't worry about your gear'it's dry and secure. Don't worry about the bag not sitting flush on the boat because this bag features a stiffener insert that conforms to the shape of the deck bow or stern.
