## Summary description

GIRO AEROHEAD MIPS is a time trial aerodynamic helmet designed for road and triathlon racing. This matte black size M (55–59 cm) helmet features MIPS technology for added rotational impact protection and an aero-optimized shell for reduced drag. Suitable for competitive time trials, triathlons and high-speed training where aerodynamics and safety matter.

## Long description

The GIRO AEROHEAD MIPS matte black size M (55–59 cm) is a time trial aerodynamic helmet designed for road and triathlon racing. It combines an aero-optimized outer shell with integrated MIPS technology to address both aerodynamic performance and rotational impact protection. The helmet is intended for riders who prioritize reduced drag and enhanced safety during high-speed efforts, time trials and triathlon bike legs.
Advantages
The helmet’s smooth, elongated shell profile reduces airflow separation and helps lower aerodynamic drag during sustained high-speed riding. Integrated MIPS provides a low-friction layer intended to reduce rotational forces transmitted to the head in certain impacts. The matte black finish offers a neutral look that pairs with a wide range of race kits while the size M fit (55–59 cm) covers a common head circumference range for adult riders. The internal padding and retention adjuster enable a close, stable fit for time trial positions.
Suitable for
 Road time trials and individual pursuit events
 Triathlon bike legs, especially non-draft or solo efforts
 High-speed training rides where aerodynamics are important
 Riders seeking an aero-focused helmet with added rotational protection
When it may not be suitable
This aero helmet is shaped for aerodynamic efficiency, which can reduce ventilation compared with more ventilated road helmets; riders who prioritize maximum cooling in very hot conditions may prefer a helmet with larger vents. It is specifically designed for time trial and triathlon positions and may be less practical for everyday commuter use or frequent stop-and-go urban riding.
Key specifications
 Intended use: time trial and triathlon road racing
 Fit size: M (55–59 cm head circumference)
 Shell finish: matte black
 Safety feature: integrated rotational impact protection layer (MIPS)
 Aerodynamics: aero-optimized elongated shell profile
 Fit system: adjustable retention and internal padding for close fit
How to use
Place the helmet level on the head so the front rim sits just above the eyebrows, then adjust the retention system until the helmet feels snug and stable without excessive pressure. Secure and position the chin strap so it is comfortable and fastens under the chin with a one-finger gap for security and comfort. For time trials and triathlons, test helmet position in your riding posture to ensure the aero profile remains effective and the fit remains stable during turns and when riding in the drops. Inspect the helmet regularly for damage and replace it after any significant impact.
What to consider before purchase
 Confirm head circumference fits size M (55–59 cm) for correct fit and safety
 Consider ventilation needs relative to typical riding temperatures and intensity
 Evaluate compatibility with eyewear and hydration systems used in time trials or triathlons
Usage recommendations
Use this GIRO AEROHEAD MIPS helmet for efforts where aerodynamic efficiency and added rotational protection are priorities. For best results, pair with a well-fitted race position, tested eyewear placement, and routine helmet inspections. Replace the helmet after any major impact and follow manufacturer care instructions for cleaning and storage.
