Stilo ST5 GT Carbon w Red Iridium Visor


The Stilo ST5 GT is the new generation of full-face helmet from Stilo. The carbon fiber shell is molded in an autoclave for maximum strength and minimum weight.

The ST5 GT is designed to satisfy those closed cockpit drivers who yearn for a larger eye port. 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, satisfying almost all racing sanctioning bodies’ requirements for helmet certifications.

Available with Integrated Electronics, Air Supply, Hydration, and Eject System (or any combination of the four), 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.

M6 nuts are integrated into each side of the shell for interfacing with a HANS Device or other head-and-neck restraint.

  • Noise attenuating earmuffs standard
  • Available with no electronics
  • Models with electronics available with ear buds or earmuffs with integrated speakers and a noise-canceling dynamic microphone
  • Intercom plug fully integrated



An effective helmet is one that fits properly. Have an assistant use a measuring tape, or a piece of string to measure the circumference of your head starting at a point approximately one inch above the eyebrows in front, around a point in the back of the head that results in the largest possible measurement, and finally wrapping back to the front. It is a good idea to take several measurements to make sure you have the largest one.
