Fox Proframe boasts ‘open-face breathability with full-face protection’. It’s a lofty claim, but with full-face certification, it certainly delivers.

With huge, gaping holes across the full width of the chin guard it certainly does all it can to maximises airflow as well.

The upper shell uses a deep, dual-density expanded polystyrene liner that Fox calls Varizorb. As the name suggests, this is designed to absorb the impact in a more progressive manner.

Peeping through the huge vent holes is the familiar yellow of a MIPS liner, too. Claimed to reduce rotational brain injuries, MIPs seems to have become a must-have technology for helmet brands in recent times.

Ensuring the Proframe is bang up-to-date in terms of technology, the simple chinstrap even gets a magnetic buckle.

As there’s no retention device, you may need to play about with different pad thicknesses to get a perfect fit with the Proframe. The brow pad, neck roll and cheek pads are all available in a variety of sizes are spares are included in the box to let you customise your fit. It’s a bit of a faff initially, but once set-up, it speeds up the process of putting the helmet on and off and it doesn’t move around on your head.

With goggles on, it’s rock-solid, and we think most riders will use the Proframe with them, particularly as it’s a tight squeeze trying to fit glasses between the helmet and the side of your head.

Putting the Proframe on is quick and easy as there’s no retention device and the strap practically does itself up thanks to the magnetic buckle. Just hold the two ends close to each other and they snap into place. It’s an important point because you’ll take your helmet off numerous times when riding the chairlift in the Alps or the shuttle van in a bike park. The last thing you want to be doing is fumbling with your helmet straps when your mates are disappearing into the distance.

Although it’s fixed, the peak doesn’t obstruct vision in any way and the rear moulding keeps goggles straps securely positioned. Best thing about the Proframe though? It’s the ventilation. There so much airflow to your mouth that it’s difficult to believe that you’re wearing a full-face.
