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.

61XL
63XXL
64XXXL

How to measure

  • Measure the circumference with a flexible tape measure at the position shown in Stilo's figure.
  • Measure the head at its widest part, above the eyebrows and ears.
  • If you are considering wearing a balaclava, measure your head while wearing it.

Fit

  • It is essential to always try on the helmet before purchasing it. The helmet size relates to the circumference (measured in centimetres) of the head.
  • The helmet must be snug, but without pressure. It should remain firmly in place when you shake your head.
  • When worn, it must not be possible to rotate the helmet around the head.

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.
