Every triathlete knows it. In the opening rush of any open water swim there are arms and legs everywhere. The risk of being kicked in the head or colliding with other swimmers is exponentially higher than in any other competitive swim situation.

We invented the world’s only protective swim cap – and we discovered it does so much more! Hammer Head® is the only cap engineered for improved head safety in the water. In addition, you can wear your Hammer Head in practice and/or under your race cap in competition and benefit from the Hammer Head’s hydrodynamic surface.
