Protective Mountain Bike Helmet GIRO FIXTURE II W matte sky blue, size Uni (50–57 cm)

GIRO FIXTURE II W matte sky blue is a women's mountain bike protective helmet sized for heads 50–57 cm (Uni). The helmet combines a durable outer shell with an impact-absorbing liner and an adjustable fit system to provide stable positioning during trail and off-road rides. Designed for recreational and commuter cyclists, it offers ventilation channels and a visor to help manage airflow and sun glare while maintaining coverage for key head areas.

Advantages

The helmet's hard outer shell protects against abrasion while the inner EPS liner is designed to absorb and dissipate impact energy. An adjustable retention system allows quick precision fit for different head shapes within the 50–57 cm range. Multiple vents promote airflow to reduce heat buildup on warmer rides, and the integrated visor shields the eyes from sun and trail debris. The matte sky blue finish provides a low-glare surface with a neutral appearance suitable for many cycling outfits.

Suitable for

• Trail and cross-country mountain biking at recreational intensity
• Commuting and urban cycling where ventilation and low weight are desired
• Cyclists who need a universal-size helmet for head circumferences 50–57 cm

When it may not be suitable

This helmet is intended for general trail and commuter use and is not a full-face model; it does not provide the extended jaw and face protection required for downhill or enduro racing. Riders seeking integrated electronic features, such as built-in lights or communication systems, should consider helmets designed with those options.

Key specifications

• Intended user: women
• Fit range: 50–57 cm head circumference (Universal size)
• Construction: hard outer shell with impact-absorbing inner liner
• Ventilation: multiple intake and exhaust vents for airflow
• Adjustment: rear retention/fit tuning system and adjustable chin straps
• Visor: integrated fixed visor for sun and debris protection
• Finish: matte sky blue

How to use

Place the helmet on the head so it sits level and covers the forehead without tilting back. Use the rear retention dial to tighten or loosen the fit until the helmet feels snug but comfortable. Adjust the side straps to form a Y-shape around each ear and fasten the chin buckle, leaving enough room to fit one or two fingers between the strap and the chin. Inspect the helmet for secure fit before every ride and replace it after any significant impact or if visible damage appears.

What to consider before purchase

• Confirm head circumference within the 50–57 cm fit range for proper protection.
• Decide whether a full-face helmet is required for the intended riding discipline.
• Check compatibility with eyewear, headlamps, or aftermarket accessories you plan to use.

Usage recommendations

Regularly clean the helmet with mild soap and water, avoid solvents, and allow it to air dry. Store the helmet away from prolonged direct sunlight and extreme temperatures. Replace the helmet after a significant crash or when signs of material degradation become apparent to maintain optimal protective performance.
