Size: 00, up to 11 kg, up to 1 year. Bema Swim Wings: The safe classics for learning to swim. Numerous swimming instructors, lifeguards, baby swimming course leaders, and parents are convinced of the safety of Bema Swim Wings. This safety is guaranteed by the double air chamber system with safety valves: If one air chamber fails, the buoyancy is still sufficient to swim to the edge of the pool. The safety check valves are submerged after inflating the swim wings and cannot be easily opened by the children. With rounded corners, the foil swim wings fit comfortably on the arm without pinching. The foil itself has been further improved. It is skin-friendly, food-safe, completely odorless, and withstands all weather and temperature fluctuations without any issues. To ensure that the swim wings fit ideally and provide the best possible support and safety in the water, they are available in four sizes for children of different ages and weight classes.
