Zoggs Tow Float Plus Swim Buoy with Dry Bag 465312

A brightly colored inflatable buoy perfect for safety when swimming in open water.
It features a low, hydrodynamic profile that causes no drag and doesn't impact your stroke in any way. It comes with a large, splash-proof 5-liter pocket that can hold an energy bar, cell phone, or tracker. The pocket is easily accessible while in the water. The inflation valve is easy to use and deflates easily with a twist of the valve.

Even though the top pocket is waterproof, it's still recommended to place cell phones and other sensitive items in extra bags or waterproof cases. For various reasons, water could enter the buoy pocket, especially if you open it while in the water.
