In an effort to make one of the most comfortable motorsport helmets on the market even better, Klim has been collecting racer, customer and dealer feedback for improvements on the F4 helmet since its introduction. This newest version has implemented these improvements and the result is a helmet that is even more comfortable and better-fitting than the original F4.
Improved ventilation via deeper air channels in the EPS liner.
Improved ventilation via larger intake and exit ports.
Improved fit of comfort liner.
Improved comfort liner ventilation via airflow perforations.
Improved moisture-wicking comfort liner via enhanced moisture-wicking fabrics and perforated foam.
Bold new graphics and colors.
RAM air induction technology with 41 air-craving intakes, the F4 sets the newest standard in helmet ventilation technology.
Non-intrusive eye port increases field of vision.
RAM air-induction scoops not only mine air as it flows over the helmet, but helps to increase the structural integrity of the helmet.
Pressure chamber network in EPS liner helps to maximize airflow over the head.
Zonal Fiber Select construction with aerospace fiberglass, carbon fiber and Kevlar ensure a safer helmet.
Included Windstopper(r) liner is small and pocketable, snaps onto foam comfort liner.
Moisture-wicking foam liner and liner material.
Includes: Cold weather liner with GORE Windstopper(r) technology, removable cheek pads, removable comfort liner, breath deflector, spare visor and visor bolt, fleece-lined comfort collar and beard flap, and deluxe nylon carrying bag.
Exceeds SNELL M2010 and U.S. DOT standards.
Intake and exhaust ports have been significantly enlarged allowing more air to enter and exit the helmet.
The EPS liner shape has been modified in three ways. The cranial shape at the top of the helmet has been altered to allow a better fit on a wider variety of head shapes and also helps keep the helmet positioned correctly. The three large air channels that run laterally through the helmet were already some of the deepest offered in any helmet, but Klim has made them deeper in this version, allowing even more air to pass over the head and out of the helmet.
The plenum chamber (inside the EPS) has also had its channels deepened, allowing an overall greater bandwidth of air to pass through the EPS to the rider's head.
The comfort liner has been completely redesigned to implement the latest technologies in moisture-wicking fabrics. Moisture-wicking foam has strategically-placed perforations allowing a much greater amount of air to pass through the liner while enhancing comfort.
With an unprecedented 41 air-craving intakes, the F4 again establishes the newest standard in helmet ventilation technology. The helmet design is optimized to effectively channel air into the helmet where it is assisted by a network of air-channels in the EPS liner to maximize airflow over the entire head. The result is a dramatically cooler and drier riding experience. The pocketable Windstopper(r) liner can be snapped onto the comfort liner in colder weather, which will still allow moisture to be moved away from the head while preventing air from directly contacting the head. Safety standards have been exceeded not only through the use of aerospace materials, but also in the design. The F4 exceeds Snell M2010 and U.S. DOT standards.
