The Giro Montaro Mips III Helmet is built for trail riders who want advanced safety, comfort, and practical features in one helmet. With Mips Evolve Core for added protection, NTA e-bike certification, and seamless integration for eyewear, it sets a high standard for performance and reliability on every ride.
Key Features and Benefits:
- Mips® Evolve Core: Reduces rotational forces in angled impacts. This added layer of protection helps lower the risk of brain injury, leading to safer rides.
- Roc Loc® Trail Fit System: Provides micro-adjustable control over tension and stability. This ensures a precise fit, so the helmet stays secure and comfortable.
- Two-Position Adjustable Visor: Moves with a single hand for easy changes mid-ride. Riders can adapt coverage, improving visibility and eye protection as conditions change.
- Integrated Sunglasses Storage: Holds glasses at the front or rear of the helmet. This prevents damage and keeps eyewear within reach, reducing distractions on the trail.
- Seamless Goggle Integration: Strap gripper keeps goggles in place without slipping. This creates a stable setup, allowing riders to focus fully on terrain and handling.
- Ionic+® Padding: Features anti-microbial and moisture-wicking properties. This controls sweat and odour, resulting in longer-lasting freshness and comfort.
- FIDLOCK® Magnetic Buckle: Fastens securely with one hand, even with gloves on. This makes fitting quick and reliable, saving time while enhancing ease of use.
Riders choose this helmet for a balance of proven protection and everyday usability. The combination of Mips safety technology, a precision fit system, and e-bike certification supports confidence across demanding trails. Added touches like goggle stability, sunglass storage, and sweat-managing padding ensure the helmet performs in both safety and comfort over time.
Take advantage of a helmet designed to meet high standards in safety and practicality. With features that protect, fit, and adapt with ease, the Montaro Mips III is ready to support your rides with reliable performance.
