Review on XELFLY Submersipack Waterproof Backpack - Submersible, Inflatable, Floating TPU Coated Durable Nylon Dry Bag With Airtight Zipper For Kayak, Fishing, Boating, Hiking, Paddle Board (Deep Blue, 18L) by Chip Palmer

This was securely closed up when it fell off of my paddleboard, so it was the last thing I was concerned about. It floated well, and I grabbed it within 15 seconds and picked it up. After fishing for about 15 minutes, I opened it to change lures. There was a bunch of water in it! People, read the 1 and 2-star reviews before spending so much money on this thing. It is not worth the risk to the valuables that you think will be protected from water.
