The EPS liner is captured by a full hardbody wrap that adds structural integrity and resistance to weather and impacts. This combination is designed to deliver dependable protection on rugged mountain trails without weighting you down on longer rides.
Montaro MIPS II emphasizes fit and comfort through its universal sizing range (55–59 cm) and a streamlined construction that balances breathability with protection. While the design focuses on protection and weight, the full-wrap shell also supports better impact distribution across a variety of terrain. Riders who value a lighter helmet without sacrificing safety will likely appreciate Montaro MIPS II for cross-country and all-mountain use.
Ventilation remains a practical consideration; while Montaro MIPS II does not list a vent count in this summary, Giro’s design philosophy typically emphasizes internal airflow channels to help keep riders cool during long climbs or hot summer descents. For riders who want a capable, lighter option with solid protection, Montaro MIPS II offers a balanced mix of features and performance for a wide range of trail conditions.

Buying Guide
Key purchase considerations
When selecting a MIPS helmet for mountain biking, consider protection level, how MIPS is implemented, ventilation, and weight. A helmet with integrated MIPS helps reduce rotational forces in angled impacts, which is especially valuable on rocky, technical terrain. If you ride aggressively or descend frequently, a full-face option may be appropriate, though it comes with added weight. Look for a durable shell, a comfortable liner, and a secure, adjustable fit system to keep the helmet stable during rough rides.
Fit, sizing, and comfort
Most helmets come in a universal or multi-size range. An adjustable or customizable fit system helps dial in the tension and fore-aft position. If you wear glasses or use a face shield, consider models that accommodate eyewear and have adequate venting to prevent fogging. Comfort is also tied to weight; lighter helmets reduce fatigue on long rides, but should not sacrifice protection.
Ventilation and climate considerations
Ventilation directly affects comfort and performance. Helmets with 18 to 27 vents, plus internal channeling, generally provide better cooling on climbs and in hot weather. In cooler environments, ventilation remains important to prevent overheating during longer descents. Choose a helmet whose venting matches your typical riding climate and the temperature ranges you encounter.
Construction and materials
In-mold designs fuse a polycarbonate shell with an impact-absorbing liner for a lighter, integrated structure. Some models feature full-wrap shells for enhanced protection and better ventilation pathways. Consider whether the helmet uses Koroyd or other energy-absorbing technologies, as these can affect weight, ventilation, and protection characteristics.
Certification and safety
Look for helmets that meet or exceed safety standards relevant to your region, such as U.S. CPSC, CE EN 1078, and AS/NZS 2063. Certifications indicate a minimum level of protection and testing. If you plan to ride in multiple countries or regions, selecting a helmet with widely recognized standards helps ensure consistent protection across settings.
Overall, the best MIPS helmet for you depends on your riding style, head size, climate, and comfort preferences. The five helmets highlighted here provide a range of protection levels and features—from lightweight cross-country models to robust trail options and a full-face helmet for aggressive riding. Use the buying guide considerations to compare options side by side and choose a helmet that fits securely, feels comfortable, and aligns with how you ride.
