Giro Aether Spherical MIPS Bicycle Helmets

The Giro Aether Spherical redefines what you expect from a high-performance helmet. Its standout feature is the Spherical Technology, an invisible protection system that utilizes two independent foam layers that rotate like a ball-and-socket to absorb impacts. This revolutionary design eliminates the uncomfortable plastic liner found in conventional MIPS systems, providing superior comfort and airflow. To keep you cool on the hottest days, the helmet features 11 massive vents connected by deep internal channels that actively pull air over your head. This is made possible by the AURA reinforcing arch, an ultra-strong, translucent structural skeleton that allows for a wide-open design without compromising safety. Achieving the perfect fit is effortless with the Roc Loc 5+ Air system, which allows you to micro-adjust both tension and vertical position with one hand. Additionally, it includes rider-focused details like rubberized docking ports to keep your sunglasses securely in place and antimicrobial padding that manages sweat and odors during long rides. Weighing only 270 grams, it is the ultimate combination of lightweight design, professional style, and the most advanced safety technology available today.

• REVOLUTIONARY SPHERICAL TECHNOLOGY: Powered by MIPS, the Aether’s unique "ball-and-socket" design redirects impact forces by allowing the outer liner to rotate around the inner liner during a crash. This eliminates the traditional plastic slip-plane for superior comfort and protection.
• ROC LOC 5+ AIR FIT SYSTEM: Experience a custom fit in seconds. This industry-leading system allows you to easily adjust fit tension and vertical position independently, ensuring the helmet stays secure and comfortable through high-intensity sprints or century rides.
• ADVANCED WIND TUNNEL VENTILATION: Engineered with deep internal channeling and massive vents that pull cool air over the scalp and push heat out. It is the ultimate choice for riders who demand maximum cooling efficiency during grueling climbs and hot summer days.
• AURA REINFORCING ARCH: The shatter-resistant, translucent AURA arch runs throughout the helmet to bolster structural integrity. This allows for massive vents without compromising the premium safety standards Giro is known for.
• PRO-LEVEL PERFORMANCE & LIGHTWEIGHT: Built for elite road performance, the Aether features a slim, aerodynamic profile and a featherweight design (approx. 270g) to reduce neck fatigue, letting you ride faster and longer with a professional aesthetic.
