What began out of empathy has become a movement to stop head injuries. Designed by a swim school owner and a parent who had both seen too many children hit their heads on the wall. Together with engineers they created the Hammer Head™ Swim Cap.

Why Hammer Head™ Swim Caps?

We take our name from the Hammerhead shark. Incredibly strong, fast and confident – our goal for all aquatic athletes when they wear the Hammer Head™ Swim Cap. Like this uniquely shaped shark, swimmers don’t have eyes on the top of their head but Hammer Head™ Swim Caps’ patent-pending HIT™ (Honeycomb Impact Technology) can help to protect them.
