Extreme Enduro competitions all over the world have been dominated by one rider and one helmet: Graham Jarvis and the revolutionary KLIM® F4. As the most ventilated helmet in motorsports, the premium F4 from KLIM® keeps Jarvis cooler in the world’s most demanding conditions. A cooler head means more energy. And more energy means better line selection, higher levels of concentration and the ability to do one-handed victory wheelies as your competition passes out. You’ve seen the YouTube clips and Red Bull Romaniacs victory salutes. Nobody pushes their bike and body further than Jarvis and the insane races he’s been winning for years.
But it’s more than just unmatched ventilation that makes the F4 victorious across all off-road zones. Built on a premium zonal fiber select platform, the KLIM® F4 features aerospace fiberglass, carbon fiber and Kevlar® layups to ensure premium safety standards are exceeded around the world. Comfort is enhanced by moisture-wicking comfort liner and cheek pad materials, comfort liner and cheek pad perforation, and the insane continuation of ventilation ducts and channels throughout the EPS.
KLIM®’s premium standards are seen in the complete F4 Package. Included with every F4 Helmet is a genuine WINDSTOPPER® packable, snap-in liner to block direct wind contact while still retaining incredibly high breathability. Also, KLIM® includes a snap-in breath deflector with every F4—making it a true four-season, multi-sport helmet. Removable cheek pads and liners wash easily (and are replaceable) and a spare visor and visor hardware are included in the ballistic nylon carrying helmet bag that comes with each F4.
To put it simply: the KLIM® F4 wins across the board. That’s what superior technology, premium features and KLIM® ingenuity deliver. Try an F4 on today and experience a new reality of comfort and performance.
