Our take on the Giro Montaro MIPS III Adult Mountain Bike Helmet

The Giro Montaro MIPS III is an adult trail mountain bike helmet built around MIPS Evolve Core rotational-impact protection. It adds trail-specific features: a two-position visor adjustable with one hand, a FIDLOCK magnetic buckle, sunglasses storage front and rear, and goggle integration. Deep internal channeling and oversized vents push air through on long climbs. It is Giro's first open-face MTB helmet certified to the NTA e-bike standard, so it suits riders on pedal trails and e-MTBs alike. Against lighter XC helmets it trades some weight for coverage and features; against enduro lids it is cooler and less bulky.

Questions and answers

What does MIPS Evolve Core do?
It is a low-friction layer inside the helmet that lets the shell slide slightly against your head in an angled impact. Giro uses it here instead of the higher-tier spherical system.
Is the Montaro MIPS III good for e-bikes?
Yes. Giro certifies it to the NTA e-bike standard, which tests at higher speeds than a standard bike helmet. It is the first open-face MTB helmet from Giro to carry that certification.
How does it compare with the Montaro MIPS II?
The III moves to MIPS Evolve Core, adds the NTA e-bike certification, and keeps the two-position visor, FIDLOCK buckle and eyewear storage. It is an update of the same trail platform rather than a new shape.
Can I store sunglasses and goggles on it?
Yes. There are front and rear sunglasses docks, and the rear of the helmet is shaped to hold goggles when you are not wearing them.
What is the FIDLOCK buckle?
It is a magnetic buckle that snaps together and releases with a sideways slide. It is designed to be easier to close one-handed or with gloves than a standard clip.
Does it meet helmet safety standards?
It is certified to CPSC and CE bike helmet standards, plus the NTA e-bike standard. That covers US and European requirements for bicycle helmets.
Where is the Giro Montaro MIPS III Adult Mountain Bike Helmet cheapest?
At Walmart, for $58.00, 71% under what the other stores charge, as of our latest check.
