The Smith Jetstream TT is our top-performing time trial helmet, ideal for road cycling. With a lightweight, aerodynamic design and energy-absorbing impact protection, this helmet offers complete confidence while racing. The magnetic visor makes it easy to switch between a color-enhancing ChromaPop lens or a clear option. Five strategically placed vents keep you cool without adding drag. The helmet features Zonal Koroyd coverage, the MIPS Brain Protection System, and is CPSC and CE EN 1078 certified for optimal protection. The fit can be adjusted with the VaporFit dial adjustment system, and the low-profile Y-strap divider ensures a secure fit and reduces wind noise and aerodynamic drag. The helmet has an Ionic+ antimicrobial lining for odor control and a lightweight, low-bulk single-layer webbing. The helmet weighs 14 oz / 410 g (size M, MIPS).
