KEKE - Back Float Swim Trainer with Elastic Strap, Shark Fin Swim Float EVA Foam for Kids Children Toddler Pool Swimming Saf

This high quality KEKE shark fin swimming float is designed not just for its cool looking. Wore on the back in the water, the verticle shape device tends to point up and align with the swimmer's vertebrate, which helps the swimmer maintain a good swimming posture, and learn to swim better. Another benefit of the verticle design is that it provides just enough amount of buoyancy for the swimmer. The lower the swimmer's body sinks below the water surface , the more buoyancy force is provided by the device (because the swim float sinks more in the water). The shark fin shape design is ergonomic, comfortable to wear and streamlined to swim. On your back, it does not restrict your body and limbs' movement in the water. The swimmer feel complete freedom and independence. It is a good way and fun to learn swim with this shark fin swim float. Kids love and enjoy water activities even more with this toy. It is also a great training aid for kid swimming class.
