I used a freezer bag with a zip but what makes the most with these kits is the cord that can attach to the kayak or have it around his neck. No risk of falling deep in water in a rollover canoeing. A small problem though on the labeling of the model to the iPad: I received a pouch that is 23x12cm. So, you can not go in an iPad. I hope this was a one-time error. I kept it because it is useful for another phone. The model of the iPad mini will to take a Kindle to the sea.
