Stilo ST5F Composite Helmet


The ST5F represents the lightest full-face formula helmet in the world, whilst maintaining the stringent quality standards of SA2015 homologation and HANS functionality.


At just 1250g (size M) before HANS, the ST5 Formula is a high-protection, lightweight option for open and closed cockpit circuit racers.

Comes with a 3mm clear visor for high clarity and protection – more visor options available from the related products list below.

Weight: XS-M – 1250g / L-XL – 1400g. HANS posts included.

How to measure your head

Measure your head as shown above, around the widest part of your head. This is generally right above your eyebrows and ears. If you plan on wearing a Balaclava (we suggest it), you should measure your head with it on.

We have significantly better results with a flexible tape measure, but if one is not available you can use a string to measure your head, and then transfer that to your measuring device.
