A life ring includes a cover formed of a knitted back polyester fabric with a top vinyl coating, and a urethane foam core within the cover. The cover and the urethane foam core are formed into a ring shape. By using the noted cover material, the life ring can be manufactured without a painting step, thereby reducing manufacturing costs and improving the consistency of the finished product.
