Giro Agilis MIPS Road Helmet Review 2026: Lightweight Protection for Triathlon Training

The Giro Agilis MIPS sits at the sweet spot between everyday road helmet and race-day upgrade. At £94.99 it’s a realistic purchase for triathletes who train hard and don’t want to write off a £300 aero lid on wet group rides. With MIPS rotational protection, Roc Loc Air fit system and 25 vents, it covers everything you need for training and standard-distance racing.

Key Specifications

MIPS: Multi-directional Impact Protection System — reduces rotational forces in angled impacts
Vents: 25 — excellent airflow for long training rides and T1 run-ups
Fit system: Roc Loc Air — tool-free dial fit, adjusts independently at the back and crown
Weight: approx. 270 g (medium)
Sizes: S (51–55 cm), M (55–59 cm), L (59–63 cm)
Certification: EN 1078 (EU); CPSC (US)

How Does It Fit?

The Roc Loc Air system is one of Giro’s best retention mechanisms. Dialling in the fit takes about 30 seconds and stays secure over cobbles and rough descents. The helmet sits mid-forward compared to Specialized or Kask equivalents — ideal for standard round-shaped heads. Oval or narrow heads should try the Kask Protone or Specialized Propero before committing.

Ventilation

25 vents is generous for a road helmet. On training rides above 22°C the airflow through the forehead and crown channels is noticeably better than budget lids with 18–20 vents. It’s not as cool as a dedicated aero-road lid like the Giro Aries Spherical, but for training volume it’s entirely comfortable.

Verdict

The Agilis MIPS is a straightforward recommendation for triathletes who want a quality, safe training helmet without overspending. MIPS protection, reliable fit and good ventilation at under £100 is genuinely good value.
