The highly attractive ultra-flexible fluorescent foam bends into any shape, but at the same time is very durable as it is made of a non-absorbent extruded polythene foam. Ideal for aquarobic classes, for fitness exercises and a perfect way to strengthen muscles in the water, especially the abdominals. Also great for relaxation and fun in the pool. Water Woggle buoyancy aids are specially endorsed by Glenda Baum, the founder of Aquarobics.
