Giro Register II XL MIPS Large Head Cycling Helmet

MIPS EVOLVE CORE Technology
When it comes to cycling safety and comfort, Giro’s MIPS EVOLVE CORE helmet sets a new standard. Engineered to minimize rotational forces during impacts—a common cause of brain injuries—this helmet integrates Mips’ innovative slip-plane system seamlessly into its design. Paired with an adjustable fit system, it ensures a secure yet personalized fit for every ride.

Lightweight & Breathable Design
Crafted using In-MoId Construction, this helmet merges a durable polycarbonate outer shell with an impact-absorbing foam liner in a single process. This fusion not only reduces weight compared to traditional helmets but also enhances ventilation through strategically placed airflow channels. Perfect for long trails or intense commutes, it keeps you cool even in sweltering conditions by directing air flow straight to your scalp via its deep internal channeling and large vents.

Roc Loc Sport Fit System
The Roc Loc Sport fit system delivers effortless one-handed adjustments across a 7cm range, making it simple to dial in your ideal fit on-the-go. With a confident click-and-lock mechanism, you’ll know your helmet stays secure without sacrificing comfort. Designed for riders of all head sizes—including those with ponytails—the system offers premium-level adjustability at an accessible price point, bridging the gap between sport performance and everyday usability.

Why Choose EVOLVE CORE?
Whether you’re tackling rugged mountain terrain or urban streets, this helmet prioritizes both protection and rider experience. Its lightweight build ensures all-day comfort without compromising safety standards, while advanced ventilation keeps you fresh during high-intensity sessions. Unlike bulkier alternatives, EVOLVE CORE combines cutting-edge Mips technology with intuitive design features that cater to cyclists seeking reliable head protection without added weight or complexity.

Ideal for trail riders and casual cyclists alike, this helmet stands out with its blend of rotational impact mitigation, breathable performance, and easy-adjust functionality—all in a sleek package built to exceed expectations on every ride.
