IN BRIEF
Giro has put the Montaro Pro on sale, the new flagship of its open-face mountain bike helmet range. It is listed at €299.99 on the brand’s European store, and $299.95 on its US site. The helmet uses the Spherical Technology developed with Mips, a ball-and-socket principle in which the outer shell rotates around the inner shell to redirect rotational forces in a crash, backed up by an internal AURA II reinforcement. Giro quotes 23 WindTunnel vents, a magnetic Fidlock buckle and an NTA certification. According to Bikerumor, Giro’s product page listed no weight as of 5 August, and the brand had at that point issued neither a press kit nor an official launch date.

The Montaro is a well-established name in the Giro catalogue: an open-face trail helmet, with no chin bar. The Californian brand has just slotted a Pro version above the range, put on sale with no fanfare and no press release.
What the Giro Montaro Pro helmet changes
The centrepiece is Spherical Technology, developed by Giro with Mips. The principle, as the brand describes it on its product page, comes down to one mechanical image: a ball-and-socket joint. The outer shell can rotate around the inner shell during an impact, which helps redirect outwards the forces that would otherwise be transmitted to the brain as rotation.
On top of that comes the internal AURA II reinforcement, presented as a translucent, impact-resistant rollcage, and an NTA certification that Bikerumor identifies as the NTA 8776 standard, written for electric bikes. Giro does indeed position the Montaro Pro explicitly for trail, enduro and electric mountain biking.

Ventilation, adjustment and goggle storage
Giro quotes 23 WindTunnel vents linked to deep internal channels, and several dedicated spots for stowing your goggles — a detail that matters more than it seems on a trail helmet, where you spend your time pushing them up onto the shell before the climbs. Closure is handled by a magnetic Fidlock buckle, which can be operated with one gloved hand.
According to Bikerumor, which looked at the helmet on 5 August, the Montaro Pro comes in three sizes, S, M and L, covering head circumferences from 51 to 63 cm, in seven colours, with Ionic+ anti-odour treated padding and a RocLoc Trail Air adjustment system. The site also notes that Giro lists no weight on its product page and has issued neither a press kit nor an official launch date — the helmet simply appeared on sale on the brand’s website.
A price in line with the top of the market
At €299.99 on Giro’s European store, the Montaro Pro sits in the upper bracket of open-face trail helmets. The brand’s US site lists it at $299.95. It is already on sale directly from Giro.
