Giro Eclipse Pro Spherical Helmet - Matte White, M (55-59cm)

The Giro Eclipse Pro Spherical Helmet is a high-performance aero road helmet built to deliver advanced speed, protection, and long-ride comfort in a lightweight design. Developed using CFD analysis and validated through wind tunnel testing, it is engineered to reduce drag and improve efficiency, achieving a measured 17% aerodynamic improvement over the previous Eclipse model. Spherical Technology powered by Mips enhances impact protection, while carefully managed airflow, low weight, and integrated sweat control systems help you maintain focus and consistency during demanding rides.Key Features and Benefits:CFD-optimised aerodynamic shell design: Computational Fluid Dynamics modelling shapes airflow around the helmet to reduce turbulence and drag. Lower aerodynamic resistance helps you maintain speed with less wasted energy, supporting sustained efficiency during fast efforts and long rides.Wind tunnel validated performance with 17% faster aero efficiency: Extensive wind tunnel testing confirms measurable aerodynamic gains over the previous Eclipse model. Verified drag reduction translates into improved momentum retention, helping you hold pace more effectively across varying conditions.Spherical Technology powered by Mips: A ball-and-socket construction allows the outer liner to rotate independently around the inner liner during angled impacts. This redirects rotational forces away from the brain, improving protection outcomes while removing hard plastic slip planes against your head for greater comfort.Aura II Reinforcing Arch structure: A shatter-resistant internal arch strengthens the helmet while allowing larger ventilation openings. Increased structural integrity supports safety standards while enabling higher airflow volume, resulting in consistent cooling without compromising durability.15 Wind Tunnel vents with deep internal channelling: Active intake vents and internal exhaust pathways move cool air through the helmet and expel heat efficiently. Continuous airflow regulation helps stabilise head temperature, reducing heat build-up during sustained high-effort riding.DryCore sweat management system: An internal silicone bead redirects moisture away from your brow before it reaches your eyes. Controlled sweat flow reduces irritation and distraction, allowing uninterrupted concentration during intense efforts.Roc Loc 5.5 Air fit system: A suspended retention system lifts the helmet slightly away from the scalp to increase airflow while allowing one-handed adjustment of tension and fore-aft positioning. Precise fit tuning improves stability and comfort, ensuring consistent helmet positioning throughout your ride.Ultra-light 280g construction with Progressive Layering EPS: Dual-density foam manages both high- and low-speed impacts while maintaining a low overall weight. Reduced mass lessens neck fatigue over long distances while delivering comprehensive energy absorption for improved protection outcomes.Efficient performance depends on maintaining speed without distraction from heat, discomfort, or instability. The Eclipse Pro combines aerodynamic shaping, advanced ventilation pathways, and refined fit adjustment to support steady output over extended periods. Progressive impact management and rotational protection technologies work alongside airflow and moisture control systems to create a helmet that supports consistent performance when effort levels remain high.If you want aerodynamic efficiency supported by advanced protection and dependable long-ride comfort, the Giro Eclipse Pro Spherical Helmet provides a focused solution designed around measurable performance gains and practical usability.
