BECO swimming discs Learn all kinds of swimming strokes at ease with these precisely shaped swim discs. They are stiffer than inflatable swimming wings and therefore move less. With a clever cut-out on the inside, your arms have all the space they need to make arm strokes. The swimming discs grow along with each other because you can click the separate discs together.
