Stilo ST5F SA2015 Composite (Formula Car)

The ST5F Composite Helmet is the same helmet shape as the ST5N Zero 8860 without the much more expensive carbon high-title shell and FIA 8860 homologation. It carries the Snell 2015 rating which satisfies almost all US Based racing sanctioning bodies  requirements for helmet certifications..

The shape of the Formula is conducive to use in open and closed cockpit cars. The optional Aero kits will optimize airflow over the helmet for open cars. Also perfect for Karting.

All Stilo shields are treated with an anti-fog treatment and they do require special care. The best result we have by far is the Stilo Visor cleaner. Liberally spray the outside of the visor with the cleaner, and wipe in a single swipe with a micro fiber towel until clean and dry.  If fingerprints or dirt remain, repeat as needed. A back and forth wiping motion will tend to leave lint from the rag on the visor, so the single pass works best. Repeat if necessary, but usually one pass works great.

Do not use Windex or any glass cleaner containing ammonia, as this can harm the anti-scratch coating on the outside of the visor, and the anti-fog coating on the inside of the visor. 

Stilo Helmet Sizing:

Measure your head 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.

Then reference the chart below to find which helmet size you should use. If you fall between sizes (IE if your head measures 56.5 cm) we would recommend using the smaller size.

We have found that customers who had previously worn a 59cm (Large) ST4 helmet are most comfortable in a 60cm (Large Plus) which utilizes the larger shell size.

There are many things we can do to adjust your helmet fit. Obviously the best thing is to come into our show room and try on the helmets, but many times, that is just not possible. One of the great things about Stilo helmets is the adjustability with helmet padding. Crown padding, Cheek padding and different ear muff sizes are all available.
