Proframe
Fox Proframe Full-Face MTB Helmets for Enduro & Trail
The Proframe category at Foxracing.si gathers Fox's lightweight full-face mountain bike helmets, built for riders who want chin-bar protection without the weight and heat of a traditional downhill lid. It is the natural choice for enduro, trail, bike park and e-MTB riders who pedal up and then descend hard, and it sits within our MTB protective equipment and bicycle helmets range.
What you will find in this category
- Fox Proframe full-face helmets – one-piece full-face construction with a fixed chin bar, an EPS liner and large vents, designed for long climbs and fast, technical descents on the same ride.
- Proframe RS – the more feature-rich version of the platform, with a magnetic Fidlock chin strap buckle, updated padding and a chin bar shaped for extra airflow.
- Sizes and colourways – the same helmet shapes in several sizes and graphics, from plain black to Fox's seasonal racing colours.
How to choose a Proframe helmet
- Fit and sizing: measure your head circumference roughly 2 cm above the eyebrows and compare it with the Fox size chart for the model. The helmet should sit level, touch evenly all around and not move when you shake your head with the strap undone.
- Protection standards: Proframe models are made as genuine full-face helmets and carry full-face certification marks such as ASTM F1952 for downhill use alongside EN 1078; always check the label inside the helmet you choose so it matches your race or bike park rules.
- Rotational impact protection: Proframe helmets use a MIPS system, a low-friction layer that allows a small amount of movement between head and shell in an angled impact.
- Ventilation and weight: this is the core reason to pick a Proframe over a heavy DH lid. Look at the number of intake and exhaust vents and the chin bar openings if you ride long, hot climbs.
- Goggle and glasses compatibility: check that the eye port and visor position suit your goggles, and that there is space to park them on the visor on the way up.
- Padding and care: removable, washable cheek pads and liner keep the helmet fresh through a season of sweat and dust.

Frequently asked questions
Is the Fox Proframe a real full-face helmet?
Yes. It has a fixed, one-piece chin bar and is built and certified as a full-face helmet, not a convertible or removable-chin design.
Can I use a Proframe for downhill and bike park?
Proframe helmets are certified to full-face downhill standards and are widely used in bike parks and enduro racing. For gravity racing always confirm the exact certification required by the organiser.
What is the difference between Proframe and Proframe RS?
Both share the lightweight, well-ventilated full-face concept. The RS version adds features such as a magnetic Fidlock buckle, revised padding and a reworked chin bar and ventilation layout.
How do I know my helmet size?
Measure your head circumference with a soft tape and match it to the Fox size chart for the specific model; if you are between sizes, choose based on how snugly the cheek pads hold your face.
When should a helmet be replaced?
Replace any helmet after a significant impact, even if the shell looks intact, and follow Fox's guidance on the age of the helmet.
