SwimFin is a swimming brand focused on helping children build confidence and develop skills in the water. Its signature product, the shark-fin-shaped SwimFin, is worn high on the back and uses progressive buoyancy to support swimmers while allowing free movement of the arms and legs. Designed as a teaching aid rather than a life jacket or personal flotation device, it is intended to encourage a natural body position, support technique practice and provide learners with feedback as they move.

The brand says its product suits a wide range of ages and abilities, including adults and people with special educational needs and disabilities, and can complement formal swimming lessons. Research and trials referenced by SwimFin, including work by the University of East London, indicate that children may make measurable progress in less time than with traditional methods. SwimFin products are available in multiple colours through its online shop.

The range also includes Funky Floaties and Dinky Divers
