The product

When releasing the initial ProFrame, Fox set the standard for lightweight and breathable full face helmets. It offered top notch protection, the breathability of a regular open face helmet and it was so light you barely noticed you had it on your head. How can you improve on that? I’m sure it was a tough assignment for the engineers and designers at Fox. Good news is, they managed. For the brand new Fox Pro Frame RS, they pulled out all stops. They focussed on three things: protection, fit and comfort.

On the protection side they partnered with Mips to create a new system called Integra Split. It features two layers of foam with a low friction liner separating the two of them. The outer layer is made with EPS foam, which is great for those high speed impacts. The inner layer is made with EPP, which works better on low speed impacts. The inner is able to move about 10mm within the outer shell, greatly reducing the amount of rotational forces in the case of a crash.

To improve the fit, Fox worked closely together with Boa. That way you can easily make micro adjustments each time you put on your helmet for the perfect fit. It’s easy to operate with and without gloves. Of course the Pro Frame RS comes with an adjustable visor that locks in three different positions. The highest position is ideal for mounting a GoPro or your goggles on the climb.

To make sure the fit is optimal, you can swap out the cheek pads for different sized ones that come included in the box. Last but not least they swapped the standard lock buckle for a Fidlock magnetic buckle, which is way easier to operate with gloves or with a little practice with just one hand.

Out on the trail

Adjustment out of the box needs a little more time than with the previous Pro Frame but it definitely pays dividends. The fidlock buckle is a favourite that we see on many other helmets. But the first thing I immediately noticed was the amazing field of view. Especially on the sides you have zero interference with your vision, which when riding is very important.

It’s great to know that you’re riding with a DH certified helmet, especially with the improvement of modern bikes leading you to hurtle yourself down the trails at faster and faster speeds. But besides protection, the main question you will ask of a full face is comfort.

On the odd climb and warmer days, the ventilation is what you can expect of the Pro Frame. It’s basically an open frame helmet with a slight weight penalty that will save you the dentist bill. And weighing in at about 850 grams it is a little bit heavier compared to the previous model. This is mainly because of the new Mips Integra Split system which is in my opinion more than worth.


Fox has raised the bar by a mile and a half. The new Pro Frame RS fits and feels like a trail helmet with a great field of view. The added protection makes the helmet DH certified and with the breathability it offers you can even wear it for the regular enduro outing. Double thumbs up!
