Looking for a carbon fiber helmet with great visibility? The ST5 GT is Stilo's latest and greatest carbon fiber helmet. They've updated the design of the ST4W GT that was so popular to include a taller and lower eyeport, giving you better visibility without compromising safety.
The modular design of the ST5 GT means that it can be outfitted with electronics, air supply or hydration systems (as well as any combination of the three), with no wires or hoses hanging from the helmet as it all integrates within the helmet shell.
Lightweight and strong, with the flexibility to work seamlessly with your onboard systems – the Stilo ST5 GT is a great choice for any racer who yearns for enhanced visibility without compromises. Check out the additional features of ST5 GT below:

The ZERO helmets are the lightest 8860 helmets available anywhere in the world, thanks to the new shell made from a specific quality of Carbon. These helmets are homologated to FIA 8860-2010 and Snell 2015 regulations.
The ST5 GT Zero 8860 helmet is aimed at professional racers needing to satisfy the strict FIA 8860 regulation, or any race driver serious about helmet safety. This certification provides an unparalleled level of puncture protection as well as impact resistance. Nowhere will you find a safer helmet.
After placing your order, a DiscoveryParts account manager will contact you so we can set up this helmet exactly the way you want. Some of these options can be installed in multiple locations and we want you to have the perfect helmet the first time.
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.
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.
