Incredible product. Allowed my daughter to find confidence in the water. Best purchase I ever made. Gave my daughter complete buoyancy and was easier to take on and off. Dries quickly and never smelled musty or mouldy. My daughter used it from 2 till 4. The only reason why we don't use it now is that she knows how to swim!
