Designed Around the Driver
The ST5.1 GT Carbon was engineered to provide maximum flexibility without compromising comfort or aerodynamics. Side ports can be configured with integrated communications, forced-air cooling, hydration systems, or helmet eject hardware. When these accessories are not installed, the helmet maintains a clean, streamlined appearance.
The enlarged eye port improves peripheral vision, helping drivers maintain awareness of traffic, corner workers, and mirrors while providing excellent compatibility with glasses.
Fit and Sizing
For the best fit, measure the circumference of your head approximately one inch above your eyebrows at the widest point. We recommend taking several measurements to ensure accuracy.
Fit Tip: Customers who normally wear a size 59 often find the size 60 more comfortable because it utilizes Stilo's larger shell size.
Compatibility
The ST5.1 GT Carbon is fully compatible with existing Stilo ST5 shields, visors, and most ST5 accessories, making it an easy upgrade for current Stilo users.
