Liv/Giant Attacca Women's Aero Road Helmet (Black/Purple) (L)
Developed in the wind tunnel. Proven by race wins against the fastest pro sprinters in the world. For competitive riders who seek every aero advantage—without compromising fit, ventilation and light weight—the all-new Attacca aero road helmet offers the winning edge.
Engineered using advanced Computational Fluid Dynamics and developed with aerodynamics experts at the Aero Concept Engineering facility in France, Attacca slices through the wind while also providing optimal ventilation. Instead of a closed front section used in some aero road helmets—a design that forces air around the helmet and cuts off ventilation—Attacca's AeroVent system channels air through the helmet. The “drag-neutral” shape of the front ports minimizes drag and offers cool ventilation at the same time.
The overall helmet profile minimizes drag for solo riders and sprinters seeking an aerodynamic advantage. It's designed to produce maximum speed in real-world rider positions and critical sprinting situations, including when a rider is in a full sprint with his head down.
Strategically placed AeroVent ports optimize airflow through the helmet, which improves aerodynamics and adds head-cooling ventilation. Three large vents in the front and two smaller side vents act as “drag-neutral” intake ports, and four rear vents (two large, two small) push air out the back.
The AeroVent ports pull incoming air through the helmet and stream it through deep internal channels from front to back. The result is consistent ventilation that helps regulate temperatures during hard efforts, while maintaining superior aerodynamics.
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 Optimal Position 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.
