Giro Aerohead MIPS Helmet Review 2026

What Is the Giro Aerohead MIPS?

The Aerohead MIPS is Giro’s dedicated time trial and triathlon helmet, sitting alongside the newer Aerohead II as the brand’s entry point into full aero-lid territory. It trades the multiple vents of a road helmet for a smooth aero shell, a wraparound eye shield, and a magnetic quick-release visor mount built for fast T1 transitions.

Verified Specs

• Fit system: Roc Loc 5 Air
• Padding: Ionic+ anti-microbial padding for odour control
• Safety: MIPS Evolve Core rotational-impact protection

Who Is It For?

This is a dedicated aero helmet for time trial and triathlon racing, not an everyday road lid — the closed shell and lack of standard vents mean it runs noticeably warmer than a training helmet, so save it for race day rather than long training rides in the heat. The magnetic eye shield is the standout feature for triathletes specifically: it detaches in one motion for a quick T1 change, which matters more than raw aero numbers if you’re racing sprint or Olympic distance where transitions count.

Buying Tips

• Get your head measured properly before buying — aero helmets fit closer and less forgivingly than vented road lids, and Roc Loc 5 Air has less adjustment range than a standard road helmet’s dial system.
• Practice removing the eye shield and helmet together in T1 before race day — the magnetic mount is fast once you know the motion, but it’s a different action from a standard road helmet strap.
• If your racing includes long, hot 70.3 or full-distance bike legs, weigh the aero gain against comfort — Giro’s own Aerohead II adds more ventilation for exactly this trade-off, at a higher price.

Care and Maintenance

Rinse sweat and salt off the padding and eye shield after every use — the Ionic+ padding manages odour but still needs washing to stay effective long-term. Store the helmet out of direct sun and away from car boots in summer, since sustained heat can degrade the EPS liner’s impact protection over time.
