Giro Montaro Pro Helmet Review: Is MIPS Spherical Worth the Hype?

### Are Helmets Really Getting Safer? You might think helmet tech has plateaued. But Giro just dropped the Montaro Pro with MIPS Spherical, and it's got people talking. At $329 (converted from €299.99), this isn't a casual buy. So, does it deliver real protection or just marketing fluff? I took it on the trail to find out. ### First Impressions and Key Specs Out of the box, the Montaro Pro feels substantial. At 14.9 oz (size S) and 16.1 oz (size M), it's not the lightest lid out there. But Giro prioritized safety over weight, which I appreciate. Here's the quick rundown: - **Technology:** MIPS Spherical - **Certification:** NTA 8776 (tougher than standard, for speed pedelecs) - **Features:** FIDLOCK magnetic buckle, vertical adjustment, glasses storage, adjustable visor - **Sizes:** S (20–21.7 in), M (21.7–23.2 in), L (23.2–24.8 in) - **Colors:** 7 options - **Price:** $329 ### What Exactly Is MIPS Spherical? MIPS Spherical is a rotational impact system that reduces twisting forces in angled crashes. Unlike traditional MIPS liners, it uses two layers of EPS foam that slide against each other, like a ball-and-socket joint. No plastic liner against your head means better ventilation and comfort. > "The best style in the world means nothing if your helmet doesn't keep you safe." That's the bottom line. And MIPS Spherical feels like a genuine step forward. ### Comfort and Fit: Details That Matter Giro didn't skimp on comfort. The Roc Loc Trail Air system lets you adjust the fit vertically, keeping the shell slightly off your head for airflow. The Ionic+ pads have pure silver for odor control—a nice touch for sweaty rides. The visor has two positions and room to stash your glasses. The FIDLOCK buckle is easy to use with one hand, and there's even an emergency info sheet. ### On the Trail: How Does It Perform? I took it on a rocky descent and a flowy jump line. The Montaro Pro stays put without pressure points. Ventilation is solid; I didn't overheat on climbs. The extra weight is noticeable but not bothersome. In a minor crash, the helmet stayed stable, and I walked away without a headache. ### The Verdict: Is It Worth $329? If you're a serious rider who values top-tier protection, the Montaro Pro is a solid investment. It's not for weight weenies, but for those who prioritize safety, MIPS Spherical is a real upgrade. The price is steep, but so is the cost of a head injury. For mountain bikers who push limits, this helmet makes a compelling case.
