Cumulative bumps on the head are serious and can be as damaging as one big strike – they can both lead to lifelong problems. The occasional and unexpected head strikes between two swimmers or the pool wall may seem minor but they’re not.

When a swimmer hits their head they begin to lose confidence and the desire to swim the backstroke, and are more apprehensive in busy practices, in warm up lanes, or in open water events.

Swimming is not a combat sport, but it is a contact sport. There has not been a solution, until now.


As an athlete you do everything your coach says, right? Eat well, sleep as much as you can, practice and train to perform at your very best for the biggest meets of the season. You wear a tech suit to reduce drag and may even shave body hair just to cut a hundredth of a second. Yet one thing has been missing from the list, your cap.

Wear your Hammer Head in practice and/or under your team cap in competition and benefit from the Hammer Head’s hydrodynamic surface.
