Swimline Underwater Swimming Hoops

If graceful, agile swimming is your goal then you need a set of Underwater Swimming Hoops from ToySplash. Spread these four 22-inch hoops around your pool and try to swim through them without touching the edges. In no time, you'll become more aware of your movements and precise in your stroke. Fill each hoop with different amounts of sand to change the buoyancy and increase the challenge! Underwater Swimming Hoops are also great additions to relay races and obstacle courses.
