Fox’s Proframe helmet, one of the first lightweight full-face helmets to hit the market five years ago, has remained unchanged until now. With its breathable, lightweight design and DH-certified protection, it has been a popular choice for enduro and downhill riding. The all-new Proframe RS improves upon the previous iteration's best features while introducing a number of safety and usability updates.
Sharing a similar silhouette to its predecessor, it is what's under the shell of the Proframe RS that truly differentiates this helmet. Outfitted with the newly developed Mips Integra Split system, Fox seeks to provide the highest level of protection possible, ensuring a DH safety certification. Mips Integra Split system utilizes both EPS and EPP foam to combat high and low-speed impacts. Designed as an integrated rotational management system, its shell-in-shell design allows the two-piece inner EPP shell to rotate seamlessly underneath the outer EPS shell in the event of an impact.
The Proframe RS is available in three sizes: SM, MD, and LG. Within those, there is a large range of adjustments made possible by the introduction of the BOA Fit System. Found on the back of the helmet, the BOA dial allows for 52-clicks of micro-adjustments, cinching down the inner liner of the helmet until the desired fit is reached. The rear cradle of the liner can also be adjusted vertically across four “steps” to ensure a proper fit from one head shape to another. Additionally, the Proframe RS comes with thicker cheek pads if the stock pads aren’t snug enough.
The folks at Fox did some quick math to reveal that across the three sizes, the four “steps”, and 52 BOA adjustments combine for a whopping 624 unique fits. While I couldn’t begin to quantify where I fell within those 624 fits, when cinched mid-way through the BOA range, a size medium felt comfortable with my head shape.
One of my biggest gripes with the previous Proframe was its fixed-position visor. Fox has rectified this by outfitting the Proframe RS with a three-position visor. The highest setting allows plenty of room to store goggles for prolonged climbs or when standing around in lift lines. The Proframe RS maintains the iconic, well-ventilated, minimalistic chin bar.
The body of the helmet sees an increase in ventilation. Most notably, it directs airflow through to the upper brow and forehead region, an area that typically becomes hot and sweaty in traditional full-face helmets. For any perspiration that does occur, the Ionic+ antimicrobial liner helps to reduce odor and wick away moisture. The chin strap utilizes a Fidlock chin strap that is easy to use with gloves on, unlike a traditional D-Ring style chin strap.
Fox has taken the beloved Proframe and injected it with industry-leading safety systems and a highly adjustable BOA fit system. By dramatically improving the lightweight build and ventilation that made the original Proframe popular, they’ve created a phenomenal contender for those in search of a lightweight full-face.
