SwimFin is the first truly new development in swimming aids for decades. Worn on the back, it does not hamper or restrict the ability to move in the water. SwimFin is a flotation device that provides as much buoyancy as the swimmer needs while helping maintain a good position in the water. Other instruction aids tend to tip the swimmer forward or hold them upright, resulting in a swimming position that impedes movement through the water, and actually makes swimming more difficult. SwimFin on the other hand gives only the support needed, giving the user the FEEL of independence, and thus encouragement and motivation. With SwimFin, the lower you are in the water the more support it will give you, as with the beginner swimmer. The higher you are in the water the less support it will give you as with an improved swimmer. SwimFin compensates for different abilities. Each SwimFin is available in a range of colors and includes TWO standard straps.
