Size guide: how to measure

Our helmet sizes are Stilo’s head circumference in cm. Stilo labels two sizes “L”: 58 and 59 on ST6, Venti and WRX helmets, 59 and 60 on ST5-based helmets.

How to measure

  • As for all Stilo helmets (see the head-circumference chart).

Fit

  • X-SMALL shell (marked * by Stilo): 'Available Only for the ZERO models. Size S 56 is the most comfortable size in this shell.'
  • For drivers transitioning from ST5 helmets, the new sizing offers enhanced comfort without compromising fit. Drivers previously using ST5 L 59 or L 60 may find the new L 59 of ST6 a better fit.
  • If the helmet is the correct size, you should feel a light, even pressure across your entire head, without localized pressure points. Always try it on with a balaclava.

About the brand

Stilo

Stilo was founded in 1999 by the former Italian rally champion Ludovico Fassitelli and is based in Bergamo, Italy. It specialises in helmets and communication systems. The range here covers full-face, open-face, WRX and kart helmets in the ST5, ST6, Venti and Trophy families, rally intercoms and radio adapters, and a wide choice of spare parts.

For each helmet, the product data lists the homologation (FIA 8859-2015 and 8859-2024, FIA 8860-2018, or Snell SA2020, SA2025 and CMR2016) and the discipline (circuit, rally or karting). It also gives the shell material, from composite to carbon in several grades, and whether the helmet is HANS-compatible and has an intercom fitted. Check the homologation your series asks for before choosing.

The spares include visors in several tints, cheek and top pads in different thicknesses, anti-fog kits, HANS anchors, peaks and cables for connecting Stilo helmets to other intercom and radio systems.

Among the racing gear brands on TrackToolFactory, Stilo combines the helmet, the intercom and the parts to maintain both. That matters most to rally crews who need the two to work together.
