The float system consists of three linked floats, one long (1) and two short (2), covered with a quick-drying synthetic material and designed to be attached to a child's or adult's swimsuit (3) so that the long float is positioned across the back of the neck with the two short ones above the shoulders. The floats can be made from compressed plastic foam or, in a variant, from a synthetic material and inflatable, with the cover attached to the swimsuit by stitches or Velcro (RTM) strips.
