I own a couple of these devices. It was developed by (and is sold by) the International Swimming Hall of Fame (ISHOF). There is a page on their web site that includes a video, testimonials, and a link to purchase the device:

You can also buy it from Kiefer:

Since I bought mine, they have improved the design. The original design tended to break where the strap attached to the buoy; the new design is more rugged. They now offer it in two sizes (23" x 10" for $34.95, or 25" x 12" for $39.95).
The nice thing about this device is that it also serves as a dry bag for carrying your stuff. For example, if I go to the beach by myself I can put my car keys in the dry bag pocket and bring them with me, instead of leaving them unguarded on the beach.
The buoy doesn't create much drag for the swimmer. After you load your stuff into the dry bag, you inflate the bladder. So when you are swimming, the bag floats and you hardly know it's there.
