Giro Eclipse Spherical Helmet

Engineered for speed and safety, the Eclipse Spherical combines cutting-edge aerodynamics with Mips® Spherical Technology to deliver superior impact protection and enhanced comfort on every ride. This lightweight aero helmet represents the pinnacle of road cycling design, offering the performance advantages serious cyclists demand without compromising on style or wearability.

Giro's Eclipse Spherical represents the pinnacle of aero helmet engineering, merging aerodynamic efficiency with advanced protective technology. Its streamlined design minimises drag across varying wind angles, whilst 14 strategically positioned vents deliver exceptional airflow for thermal management. The Spherical Technology framework, integrated with Mips® brain protection, enables independent rotation of foam layers during impact to dissipate forces effectively. Progressive Layering enhances overall crash protection, whilst the refined Roc Loc® 5 Air retention system ensures secure, stable positioning. Antimicrobial Ionic+ padding manages moisture whilst maintaining durability—purpose-built for road and gravel racing demands.

• TRANSFORM AIR — Transform Air Technology actively streamlines airflow to reduce drag across multiple wind angles. It optimizes aerodynamics by making the helmet appear longer to the wind; while still retaining an aero advantage in a head-down sprinting position.
• 14 WIND TUNNEL VENTS — Giro helmets are engineered with our proprietary Wind Tunnel venting system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust cool; fresh air over and around the rider's head while forcing heat and stale air out.
• SPHERICAL TECHNOLOGY — Spherical Technology's Ball-and-Socket design; powered by Mips®; helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin.
• PROGRESSIVE LAYERING™ — Giro helmets designed with Progressive Layering™ use dual-density EPS foam liners to address high- and low-speed impacts for more comprehensive energy management.
• DEEP INTERNAL CHANNELING — The inner liner of the helmet is aggressively engineered to assist air flowing through the helmet; working in conjunction with our Wind Tunnel vents to provide an easy pathway for cool air to flow in and hot air to exhaust out.
• ROC LOC® 5.5 AIR FIT SYSTEM — Using a patented design that suspends the helmet just slightly off the top of the skull; Roc Loc® 5.5 Air allows cool airflow to pass directly over your head; further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet. Fit and adjustments mimic the Roc Loc 5; allowing you to easily custom fine-tune fit tension and fore-aft tilt in seconds using just one hand. Reflective decals provide added visibility.
• IONIC+ ® PADDING — Pure silver is the ingredient that gives IONIC+® padding the power to provide permanent; natural odor protection to keep your helmet feeling fresh.
