Stilo helmets are available in different shell sizes within the range of full face and open face helmets. ST5 helmets (full face) come in two shell sizes: small and large. The small shell covers all sizes from 54 (XS) to 59 (L). The large shell is size 60 (L+) to 64 (XXXL) The only exceptions to this are the ST5 CMR junior karting helmet which is only available in a new reduced size (narrower) small shell from 54 (XS) to 59 (L).

In Venti WRC, WRX and Trophy (open face) models, Stilo have developed a third (medium) shell size to keep mass and weight as minimal as possible for the most popular of sizes, 59 and 61. So now, for this range, 54 (XS) to 58 (L) are in a small shell, 59 (L) and 61 (XL) are in the new medium shell and 63 (XXL) and 64 (XXXL) are in the large size shell. Another development from Stilo in the new Venti range is that for the first time, Carbon, 8860 and Zero models are all available in the largest size shell, something not previously available in the outgoing models and this is also a size that other open face helmet brands do not offer.

Stilo Venti and ST5 helmets generally are a little tighter fitting than some other brands, so do bear this in mind when choosing your helmet size and speak with us if you need some help on this.

With the new Stilo Sport range of clubman open face helmets, there are two shell sizes, XS to M are covered by the small shell size and L & XL are covered by the large shell. One point to note is that the internal linings of the Stilo Sport range are a different fit to the WRC helmets, and the fit is a little more relaxed and are more true to size.

At Nicky Grist Motorsports we understand the importance of a well fitting helmet. Get it right and you are on a fast track to optimum performance, but get it wrong and you’ll suffer distractions and discomfort that can put your safety at risk.

The key thing to remember is not to simply take the circumference measurement and buy a helmet based on that size. We need to look at the width and length of your head also, as that does affect the helmet size you need.

To measure your head as accurately as possible and to help us provide you with the optimum fit, please measure as shown below and make a note of your sizing to send to us. Always wear a balaclava when taking head measurement for a helmet as the extra 2-3mm does make a difference to the circumference measurement and it also presses your ears nice and close to your head.
