## Summary description

GIRO SOURCE MIPS is a mountain bike helmet featuring MIPS rotational protection and a matte white finish. Size M fits head circumferences 55–59 cm.

## Long description

GIRO SOURCE MIPS — matte white, size M (55–59 cm) is a mountain bike helmet engineered for trail and cross-country riding. It integrates a multi-impact shell design with MIPS rotational protection to reduce rotational forces during oblique impacts. The helmet includes a ventilation layout, adjustable fit system and extended rear coverage typical for off-road use, offering a balance of impact mitigation, comfort and fit for everyday mountain and gravel cycling.
Advantages
The helmet combines MIPS rotational protection with a lightweight yet durable shell and energy-absorbing liner to address linear and rotational impact forces. An adjustable retention system allows precise fit for head circumferences within the M size range, while the matte white finish provides a neutral appearance that is easy to maintain. Integrated vents and internal channeling support airflow to help manage heat on longer rides.
Suitable for
 Trail and enduro-style mountain biking where extended rear coverage is beneficial
 Cross-country and gravel rides requiring ventilation and low weight
 Everyday off-road training and recreational cycling
 Riders seeking MIPS rotational protection in a medium-sized helmet
When it may not be suitable
This helmet is designed for mountain and cross-country applications; it may not be the best choice for downhill racing where additional face protection or a full-face helmet is required. It is sized for head circumferences of 55–59 cm, so riders outside that range will need a different size. The matte white finish, while practical, shows dirt and scuffs more readily than darker colors.
Key specifications
 Intended use: mountain bike / cross-country
 Safety system: MIPS rotational protection integrated into helmet construction
 Shell: lightweight, impact-resistant outer shell with energy-absorbing liner
 Fit range: medium size suitable for 55–59 cm head circumference
 Ventilation: multiple vents with internal channeling for airflow
 Finish: matte white
 Retention: adjustable rear fit system and chin strap with buckle
How to use
Place the helmet on the head so that it sits level and covers the forehead without tipping backward. Adjust the rear retention dial or fit mechanism until the helmet is snug but comfortable. Fasten and adjust the chin strap so it forms a V just below each ear and the buckle sits centered under the chin; the strap should be tight enough that the helmet does not move excessively but loose enough for comfortable breathing and talking. Replace the helmet after any significant impact or if the liner or shell shows visible damage.
What to consider before purchase
 Measure your head circumference to confirm it falls within the 55–59 cm range for size M
 Decide if MIPS rotational protection and extended rear coverage meet your riding discipline requirements
 Consider helmet color and maintenance — matte white is more prone to visible dirt and marks
 Check compatibility with any eyewear, communications or camera mounts you plan to use
Usage recommendations
For best protection and comfort, ensure the helmet is correctly fitted before every ride, keep vents free of debris, and replace the helmet after a significant crash or if structural damage is present. Periodically inspect straps, buckles and the fit system for wear and proper function.
