FOX PROFRAME RS HEATSTACK MIPS HELMET

The Fox Proframe RS Heatstack MIPS full-face helmet is built for riders who pedal uphill and then want the protection of a proper full face on the way down. Light, very well ventilated and downhill certified, it is an enduro MTB helmet you can wear from the first climb to the last descent, without strapping it to your pack on the transfers.

Compared with the Proframe that many riders already know, the RS version introduces a completely reworked impact absorption system, a finely adjustable fit and a series of details that make the difference on long days, from the magnetic buckle to the action cam mount. The Heatstack graphic, in Dark Yellow and Arctic Blue, gives it a bold look that stands out on the trail.

MIPS Integra Split protection on the Fox Proframe RS full-face helmet

• MIPS Integra Split system: an EPP layer paired with an EPS layer, with a low-friction layer in between that helps reduce rotational forces in a crash
• Dual-density construction designed to manage both low-speed and harder impacts
• ASTM F1952 downhill MTB certification

BOA fit and comfort for enduro

• BOA adjustment with a micro-dial you can turn while wearing the helmet
• Rear cradle with four adjustment positions to match the shape of your head
• Two sets of cheek pads: 20/30 mm fitted as standard and 30/40 mm included in the box
• Ionic+ liner and cheek pads with antimicrobial treatment
• Fidlock magnetic buckle, easy to open and close even with gloves on

Ventilation, visor and GoPro mount

The shell has more vents and a reduced contact area with the head, so heat escapes even on slow climbs. The visor adjusts to three positions and leaves room to park your goggles when you are not wearing them, while a removable GoPro mount, included, sits under the visor so you can film your descents from a natural point of view.

Why choose the Fox Proframe RS Heatstack MIPS

• A light full face (around 790 g in size M) that is easy to wear on long climbs
• MIPS rotational protection built into the structure, not just an added insert
• Precise fit thanks to BOA and interchangeable cheek pads
• Ideal for enduro, aggressive trail riding, e-MTB and bike park days

If you want a helmet that does not force you to choose between breathing on the climbs and feeling protected on the descents, the Fox Proframe RS Heatstack MIPS is the most complete answer in the Fox range.
