Giro Radix MIPS Adult Dirt Bike Helmet

Product Overview

The Giro Radix MIPS Adult Dirt Bike Helmet is engineered for trail riders who demand both performance and protection during long, challenging rides. Built to meet the rigorous needs of core trail enthusiasts, this helmet delivers rugged durability alongside lightweight comfort and superior ventilation. Its advanced design ensures all-day confidence on the trail by combining impact resistance with an ergonomic fit system. The integrated MIPS technology provides added safety against rotational forces during angled impacts, making it a smart choice for serious mountain bikers. With features like customizable fit adjustment and effective airflow management, this helmet supports sustained riding performance without compromising safety.

Key Features

• Integrated Mips Brain Protection System: This system works within the helmet to reduce rotational forces that can occur during angled impacts. By incorporating a slip plane layer, the Mips technology enhances overall protection while maintaining comfort and secure fit through compatibility with the adjustable Roc Loc® 5 system.
• Hardshell with In-Mold Hardbody Lower Wrap: Constructed from a durable outer hard shell fused permanently to the EPS foam liner using In-Mold technology, this design improves structural integrity without adding unnecessary weight. The polycarbonate lower wrap increases resistance to abrasion and impact, ensuring long-term durability on rough terrain.
• P.O.V. Visor with Adjustment Mechanism: The P.O.V. (Point of View) visor offers four distinct positions—three for optimal riding visibility and one high position for storing goggles above the brow. The mechanism allows for one-handed adjustments while riding, giving riders quick access to improved sightlines or goggle clearance as needed.
• Roc Loc 5 Fit System: This industry-leading fit system enables rapid customization of both tension and fore-aft tilt using a single hand. It enhances stability and comfort over extended periods, offering a snug, personalized fit that reduces slippage and improves balance during dynamic trail movements.
• Wind Tunnel Ventilation: Developed through proprietary testing, the Wind Tunnel ventilation system actively draws cool air into the helmet via strategically placed vents. Exhaust channels then push heat and stale air out, maintaining consistent airflow across the head. This results in reduced fogging and enhanced thermal comfort throughout long rides.

No additional accessories or replacement parts are included unless specified in the packaging details provided at purchase. Always ensure proper fit before each ride by adjusting the Roc Loc 5 system according to manufacturer guidelines.
