Regular price $942.00

Stilo ST5 GT Wide Composite Matte Black SA2015 Helmet

The Stilo ST5 is the new generation of full face helmet from Stilo.

The ST5 GT is designed to satisfy those closed cockpit drivers who yearn for a larger eyeport. The cutout for the eyeport is taller than the standard Formula version and has a special visor to accommodate the larger opening.

The ST5 GT carries a Snell 2015 certification which satisfies almost all racing sanctioning bodies’ requirements for helmet certifications.

Available with integrated Electronics, Air Supply and Hydration or any combination of the three, this helmet offers flexibility while maintaining a clean cabin. There are no wires or hoses hanging down below the helmet – everything integrates seamlessly with the shell of the helmet. These additional options can be addded by choosing the items to the right.

Features an M6 nut integrated into the shell for interfacing with Head and Neck Restraints.

Helmet Fitment Guide


How to Measure Your Head

Measure your head as shown, 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.


Next, 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.

Extra Small (54cm) 53-54 cm 21 - 211/4 65/8 - 63/4 Small Shell
Small (55cm) 55-56 cm 215/8 - 22 67/8 - 7 Small Shell
Medium (57cm) 57-58 cm 223/8 - 223/4 71/8 - 71/4 Small Shell
Large (59cm) 59-60 cm 231/4 - 235/8 71/4 - 71/2 Small Shell
Large Plus (60cm) 60-61 cm 231/4 - 235/8 71/4 - 71/2 Large Shell
Extra Large (61cm) 61-62 cm 24 - 243/8 75/8 - 73/4 Large Shell

Please Note: 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.
