## Long description

The GIRO SOURCE MIPS MTB Helmet in matte black, size M (55–59 cm), is a trail and cross-country cycling helmet designed to provide reliable head protection with a focus on impact management and comfort. It features MIPS (Multi-directional Impact Protection System) to reduce rotational forces in certain impacts, an in-mold shell construction for structural integrity and weight savings, ventilation channels to help manage airflow, and an adjustable fit system to secure the helmet on a variety of head shapes.
Advantages
The helmet combines MIPS technology with an in-mold construction that balances protection and low weight, while ventilation channels help maintain airflow on longer rides. An adjustable fit system allows quick personalization for a consistent, secure fit and the matte black finish offers a neutral aesthetic that suits a range of riding styles and gear.
Suitable for
 Trail riding and cross-country (XC) cycling
 Daily training rides and endurance sessions
 Riders seeking added rotational impact protection
 Cyclists who prefer a medium-size helmet (55–59 cm)
When it may not be suitable
This helmet is optimized for trail and cross-country use and may lack features specific to downhill or enduro racing, such as extended rear coverage or an integrated chin bar. Riders who require full-face protection or a helmet certified for motorized vehicles should consider other products tailored to those use cases.
Key specifications
 Fit size: Medium (55–59 cm)
 Color: Matte black
 Protection system: MIPS (Multi-directional Impact Protection System)
 Construction: In-mold shell
 Ventilation: Multiple airflow channels
 Adjustment: Adjustable fit system for secure fit
 Intended use: Mountain biking – trail and cross-country
How to use
Place the helmet level on the head so the front edge sits just above the eyebrows. Use the adjustable fit system to tighten the helmet until it sits securely without excessive pressure. Fasten and adjust the chin straps so they form a V under each ear and allow one or two fingers of space between the strap and the chin. Inspect the helmet for visible damage before each ride and replace it if it has sustained a significant impact or shows cracks, deformations, or compromised padding.
What to consider before purchase
 Measure your head circumference to ensure the 55–59 cm size is appropriate.
 Decide whether MIPS rotational protection aligns with your safety preferences.
 Consider whether trail/XC coverage meets your riding style or if extended protection is needed.
Usage recommendations
Use the GIRO SOURCE MIPS helmet for organized trail rides, cross-country training, and regular mountain-bike outings. Replace the helmet after any significant impact, and clean it with mild soap and water; avoid solvents or high-heat drying to preserve shell and liner integrity.
