Giro Aries Spherical Helmet White

A helmet that feels like it isn’t there—the all-new Aries Spherical is truly unlike anything before. Its sleek design and lightweight construction (just 270 grams in size medium, CE certified) deliver exceptional comfort and ventilation.

Spherical Technology, Giro’s innovative ball-and-socket system powered by MIPS, enhances protection by redirecting rotational energy away from the brain in certain impacts. Progressive Layering with dual-density Nanobead EPS foam provides comprehensive energy management.

With 24 Wind Tunnel vents optimized by the AURA II Reinforcement Arch and a plush DryCore brow pad that wicks sweat, airflow and comfort are maximized. The Roc Loc 5+ Air fit system ensures precise adjustability, while full lower hardbody coverage improves durability. Meticulous craftsmanship makes the Aries a helmet that combines state-of-the-art performance, protection, and style.

KEY FEATURES

• AURA II REINFORCING ARCH - The shatter-resistant, translucent Aura II Reinforcing Arch spans the helmet, enhancing structural strength while enabling large vents for optimal cooling.
• VIRGINIA TECH #1 RANKING - Researchers at the independent testing facility Virginia Tech awarded the Aries Spherical their highest rating in helmet safety, recognizing its effectiveness in reducing the risk of injury. All Giro helmets equipped with Spherical Technology have achieved the top 5-star rating.
• DRYCORE - The DryCore® sweat management system uses an internal silicone bead to channel moisture away from the rider’s brow, preventing sweat from dripping into the eyes and reducing irritation.
• 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 independently around the inner liner during a crash. It also prevents direct contact between hard plastic or slip-plane surfaces and the rider’s skin.
• MIPS BRAIN PROTECTION SYSTEM - All Giro helmets are engineered to minimize energy transfer while exceeding strict safety standards. Helmets equipped with MIPS technology are designed to reduce rotational forces, helping limit the amount of rotational energy that could be transmitted to the rider’s brain in certain impacts.
• 21 WIND TUNNEL VENTS - Giro helmets feature our proprietary Wind Tunnel ventilation system, which pairs active vents in the helmet shell with internal exhaust channels. This design directs cool, fresh air over and around the rider’s head while efficiently expelling heat and stale air.
• DEEP INTERNAL CHANNELING - Paired with the large vents, the internal channels direct airflow across the scalp, delivering exceptional cooling performance.
• PROGRESSIVE LAYERING - Giro helmets featuring Progressive Layering utilize dual-density EPS foam liners to effectively manage both high- and low-speed impacts, providing more complete energy absorption and protection.
• EYEWEAR DOCKING PORTS - Integrated eyewear docking ports with rubber grips keep sunglasses securely in place.
• REFLECTIVE DETAILS - Reflective details improve visibility in low-light or nighttime conditions by reflecting light—such as from headlights—back toward the source, making the rider more noticeable to drivers.
• ROC LOC 5+ AIR FIT SYSTEM - This innovative fit system elevates helmet performance by improving cooling, fit, comfort, and stability. The patented Roc Loc 5+ Air design suspends the helmet slightly above the top of the skull, allowing cool airflow to circulate directly over the head and enhancing the effectiveness of the vents and internal channels that expel heat. Fit adjustments work like the Roc Loc 5, enabling riders to easily fine-tune both tension and fore-aft tilt in seconds using just one hand.
• IONIC+ PADDING - Pure Silver is the key component in IONIC+, delivering natural, long-lasting odor protection to keep your helmet fresh.
• Circumference: S 51 - 55 cm | M 55 - 59 cm | L 59 - 63 cm | XL 63 - 65 cm
