Giro's exact US Montaro MIPS III style 132 page documents an open-face trail helmet, CPSC/CE statements, and NTA 8776. At 57 cm, the adult chart points to Medium; confirm your personal fit and the exact physical label before relying on either.

Assessment scenario: Adult trail assessment with CPSC evidence at 57 cm
An assessment scenario for an adult trail rider whose 57 cm circumference falls inside Giro's Medium guide interval and who requires a documented US CPSC statement. A chart match is only a reason to try the exact helmet; it does not establish fit or guarantee protection.
Explore this buying guide ↗Why consider this model?
- The exact US page describes Montaro MIPS III as open-face MTB equipment for trail use and states CPSC/CE compliance and NTA 8776 e-bike standard certification.
- Giro's size chart places 57 cm in the Medium 55–59 cm interval for this page's S/M/L options; this is a try-on starting point, not a fitted result.
- The reviewed style documents Mips Evolve Core, a Roc Loc Trail/Trail Air fit system, two-position visor, front/rear sunglasses holders, goggle gripper, and FIDLOCK buckle.
Tradeoffs to weigh
- The manufacturer page calls the system Roc Loc Trail in one section and Roc Loc Trail Air in another; the review preserves the naming ambiguity and does not claim an individual's fit.
- The III is not identified as Spherical Technology; its 450 g Medium figure is manufacturer-stated and no independent test or measured comfort result is available.
- The product page lists S/M/L only, ending at the 63 cm chart boundary; no vent count or III-specific camera/light mount statement is published there.
Check these before ordering
- Confirm Giro US style 100000000500000132 and the selected size and finish. The observed Matte Motion Orange / M variant is SKU GR-7201970; another size or color can have a different SKU.
- Inspect the exact helmet's CPSC/CE and NTA 8776 label and its instructions; do not treat the landing-page summary as a physical inspection or transfer its statements to another Montaro generation.
- Try the actual size with Giro's fitting instructions and your normal eyewear; reject it if the shell sits unevenly or cannot be retained securely.
- Confirm package contents, seller identity, condition, return terms, and current recall notices before choosing an offer.
