Most companies that manufacture and design kayak helmets are the very people that use them for competition or recreation.
Predator Helmets is owned by an avid whitewater and slalom kayak competitor and Shred Ready Helmets was founded by a slalom kayak competitor who actually trained for the 1996 Olympic Games.
There are many different types of kayak helmets to choose from. Whether you want a helmet like the Pro-Tec Classic Full Cut that has 17 vents for ultimate drainage and ventilation, or there are many full face helmets like that Shred Ready Carbon Full Face with a four point retention system.
A lot of these helmets are also designed for use in water skiing and wakeboarding making the investment in a water helmet well spent.
