## Summary description

GIRO RADIX MIPS is a mountain bike helmet with MIPS rotational impact protection, sized M (55–59 cm) in matte white finish. Designed for trail and all-mountain riding, it features integrated ventilation, adjustable fit system and impact-absorbing construction to enhance rider safety and comfort during off-road cycling.

## Long description

The GIRO RADIX MIPS Mountain Bike Helmet in size M (55–59 cm) with a matte white finish is a helmet built for trail and all-mountain riding. It integrates MIPS rotational impact protection with a multi-zone impact-absorbing shell and an adjustable fit system to balance protection, ventilation and comfort for off-road cycling. The design targets riders who need a reliable helmet for varied terrain while maintaining a low-profile appearance.
Advantages
The helmet combines rotational impact mitigation with a molded outer shell and energy-absorbing liner for improved protection in angled impacts. Integrated ventilation channels support airflow to reduce heat buildup on long climbs and technical sections. A micro-adjustable retention system and padded interior provide a secure, customizable fit for head sizes within the 55–59 cm range. The matte white finish offers a neutral, low-reflective aesthetic that works with different riding kits.
Suitable for
 Trail riding and all-mountain cycling where mixed terrain and moderate technical features are present
 Day-long rides requiring sustained ventilation and comfort
 Riders seeking a helmet with rotational impact protection (MIPS) for enhanced safety
 Commuting or short off-road transfers where a lightweight, well-ventilated helmet is preferred
When it may not be suitable
This helmet is designed primarily for trail and all-mountain use and may not be ideal for riders who require full-face head coverage for downhill racing or highly aggressive enduro courses. It also may not suit those who need an extremely lightweight competition road helmet optimized solely for aerodynamics rather than off-road protection and ventilation.
Key specifications
 Fit range: Medium size head circumference 55–59 cm
 Protection: Rotational impact protection system integrated into the liner
 Construction: Molded outer shell with multi-zone impact-absorbing liner
 Ventilation: Integrated airflow channels for heat dissipation
 Fit system: Micro-adjustable retention and padded interior for comfort
 Finish: Matte white exterior
How to use
Place the helmet level on the head so the front edge sits just above the eyebrows for proper forehead coverage. Adjust the micro-adjustable retention system until the helmet feels snug but not tight, allowing for minor movement without shifting. Fasten and adjust the chin straps so they form a V under each ear and tighten the buckle to a comfortable, secure fit. Regularly inspect the helmet for signs of damage and replace it after any significant impact or according to the manufacturer’s recommended service life.
What to consider before purchase
 Measure your head circumference to confirm the 55–59 cm fit range is correct
 Decide if rotational protection and off-road ventilation match your riding style
 Consider compatibility with accessories (e.g., goggles, helmet lights) you plan to use
 Check weight and comfort preferences if you ride long distances or prioritize minimal bulk
Usage recommendations
Use the helmet for trail and all-mountain rides where a balance of ventilation, protection and adjustability is required. Replace the helmet after any significant impact, follow periodic inspections, and ensure a proper fit before each ride to maintain intended protection levels.
