Neoprene caps protect your head from the cold. You can choose from 1.5 to 3 mm thick neoprene products from reputable manufacturers such as TYR, Aqua Sphere or Hiko. The caps also cover your ears and keep your head warm even in extremely cold water thanks to the perfect thermal insulation. Try our new Swimaholic neoprene headband too! You can choose a cap that can be fastened under the chin or without a fastener.
