The overall helmet profile minimizes drag for solo riders and sprinters seeking an aerodynamic advantage. Designed to produce maximum speed in real-world rider positions.

From the crown of the helmet toward the rear, two dimples—one on each side—help channel airflow through the helmet. CFD simulations and third-party wind-tunnel tests show that the dimpled shapes optimize average aero performance in various rider positions and wind directions.

Strategically placed AeroVent ports optimize airflow through the helmet, which improves aerodynamics and adds head-cooling ventilation. Six generous vents in the front and two smaller side vents act as “drag-neutral” the back.

The AeroVent ports pull incoming air through the helmet and stream it through deep, wide internal channels from front to back. The result is consistent ventilation that helps regulate temperatures during hard efforts, while maintaining superior aerodynamics.

Multi-density foam construction, lower density on the upper allows the helmet to better mitigate the energy found in more common low speed impacts, while a higher density foam on the lower area attenuates high speed impacts.

The perfect blend of security and comfort. Cinch Pro offers optimal coverage by cradling the occipital bone for full protection, support and comfort. Large scoop-like paddles protrude outward to cradle the head.

ESS combines Giant’s light, micro-adjustable Cinch Pro fit system with TriGlide positioning dividers and LiteForm webbing, resulting in a single-purpose fit and retention system with a secure, comfortable fit right out of the box.

These highly advanced natural fabrics fight bacteria growth by pulling sweat from a rider’s head and transferring it through the AeroVent exhaust ports. The natural property of the fabric inhibits microbes that cause odors.
