Swim ring

The swim ring was derived from the inner tube, the inflatable inner part of older vehicle tires.

Some designs even appear as more than one tube sewn together, and include 2 or 4 holes so that more than one rider can fit comfortably.

Although similar in appearance to a lifebuoy, a swim ring is not designed to save individuals from drowning.

A swim ring consists of two identically-sized layers of flat plastic, one of which contains a valve for inflation and deflation.

Animal-shaped rings sometimes include an additional air chamber in the shape of a forward-facing animal head on the upper side of the ring, with more complex designs also featuring further chambers to represent limbs, tails, wings, etc.
