Hammer Head Swim Cap


Hammerhead is designed with HIT technology, a patented cushion inside to minimize accidental and repetitive head hits in the pool or open water alike making it 50% safer than other swim caps. It is designed for racing with a wrinkle-free dome surface that reduces frontal drag by up to 10.5%. It is also comes in three sizes, giving you the most comfortable fit and not one Hammer Head has ever torn, making it the most durable swim cap on the market.


Head Safety

The world’s only protective swim cap has tiny honeycomb pillars inside the cap provide an invisible protective layer, absorbing the shock from accidental and repetitive impact with a pool wall or other aquatic athletes. Head hits occur above and below the surface and it’s time aquatic sports had protection.

Ideal for racing, because of its wrinkle-free, hydrodynamic dome exterior surface making it up to 10.5% faster. Testing at top speeds showed it can reduce roughly 0.6 seconds in a 50 Free, which can easily be the difference between winning and losing a race. Now that is a competitive advantage!
