Product Description

In an effort to make one of the most comfortable motorsport helmets on the market even better, we've been collecting racer, customer and dealer feedback for improvements on the F4 helmet since it's 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.

Features

• 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 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 three large air channels that run laterally through the helmet were already some of the deepest offered in any helmet, but we have made them deeper in this version, allowing even more air to pass over the head and out of the helmet.
• The pocketable WINDSTOPPER 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.
• The F4 exceeds Snell M2010 and U.S. DOT standards

good helmet - Unbelievable customer service
By Maurice D. Brown
Best vented helmet out there. Fit with goggles is perfect. Breathbox is nonsuffocating.

The best part of my experience however was the amazing customer service form Helmet City. Wow. Kyle helped me work through issues trying to get a helmet ordered remotely to fit. Extremely knowledgeable and friendly. Wish all online transations could be like this.

Great Helmet Size Runs Small
By Idaho Mom
We own two of these helmets in our home. They are very light and the interior protection is comfortable and makes for a great fit. There is little to no movement or shaking around your head. The extra visor and interior pieces are great to have also.

I also really like that the padding on the interior can be removed. This is very helpful for cleaning and drying. The venting in the top of the helmet helps to keep away excessive sweating on those days that it may be warm when riding.

The helmet is expensive compared to others on the market but the quality and extras are worth the charge. Sizing runs very small in these helmets. I usually wear a kids large and bought an adult large in this helmet. My husband wears a large and purchased the XXXL size in Klim helmet.
