## Long description

The GIRO Radix MIPS in matte black, size L (59–63 cm), is a mountain bike helmet built for trail and enduro riding. It combines a multi-impact EPS liner with an integrated MIPS rotational protection system, an adjustable fit mechanism and an array of vents to balance protection with airflow. The helmet is intended to offer reliable coverage for off-road riding, daily trail sessions and more aggressive descents while maintaining a stable, comfortable fit for larger head sizes.
Advantages
This helmet integrates MIPS rotational protection with a multi-impact EPS liner to reduce rotational and linear forces in certain impacts. An adjustable fit system and size L shell provide a secure fit for head circumferences between 59 and 63 cm. Multiple vents and internal channeling are designed to promote airflow and heat management during prolonged efforts. The matte black finish offers a low-glare, neutral appearance that pairs with a variety of riding kits and protective gear.
Suitable for
 Trail riding and singletrack sessions
 Enduro and aggressive descents where additional rotational protection is desirable
 All-day rides where ventilation and a stable fit are important
 Riders with head sizes in the 59–63 cm range
When it may not be suitable
This helmet is designed for mountain biking and trail use and may not be optimal for road racing or time trial events where aerodynamic helmets are preferred. It may also be larger than necessary for riders with smaller head circumferences; users outside the 59–63 cm range should choose a different size to ensure proper fit and protection.
Key specifications
 Intended use: trail and enduro mountain biking
 Protection systems: multi-impact EPS liner and integrated rotational protection layer
 Fit adjustability: rear fit system with micro-adjustment
 Ventilation: multiple intake and exhaust vents with internal channeling
 Shell finish: matte black
 Size range: L for head circumference 59–63 cm
How to use
Measure your head circumference and confirm that it falls within the 59–63 cm range before fitting the size L helmet. Position the helmet level on the head so the front rim sits just above the eyebrows, fasten and adjust the chin strap to sit snugly under the chin without restricting movement, and use the rear micro-adjustment fit system to fine-tune lateral and vertical position. Ensure vents are unobstructed and periodically inspect straps, buckles and the shell for wear or damage. Replace the helmet after any significant impact or if structural damage is visible.
What to consider before purchase
 Confirm head circumference falls within 59–63 cm for correct sizing
 Decide if integrated rotational protection (MIPS) and multi-impact liner match your protection needs
 Consider ventilation needs for your typical riding conditions
 Check compatibility with eyewear, goggles and any communication or camera mounts you use
Usage recommendations
For best protection and comfort, pair the GIRO Radix MIPS helmet with well-adjusted straps and goggles or glasses that sit comfortably with the helmet’s brim and vent placement. Replace the helmet after a crash or when signs of damage appear, and follow manufacturer guidance for cleaning and storage to maintain performance.
