The first portion of a triathlon is the open water swim, and with mass starts back, it's crucial to consider personal head protection. This part of the race can be intimidating and up until now there was nothing to mitigate head hits when you have limited visibility, splashing water, and close encounters with other athletes. Traffic jams at buoy turns, floating debris and rough waters add to the danger, especially with officials in turbulent boats and kayaks nearby. Knowing these risk zones can help you navigate safely.

Hammer Head® Swim Caps are here to change the playing field. Our proprietary safety technology cushion inside is designed to make you and your teammates safer in the water, improving your confidence and helping you compete at the highest level.
