### Is This the Safest Helmet for Your Money? Are helmets actually getting safer, or are we just paying more for fancy names? Giro thinks there's room for improvement, and they've launched the Montaro Pro with MIPS Spherical technology. At $329 (converted from €299.99), it's not cheap. But does it deliver real protection? We took it on the trail to find out. At the end of the day, style means nothing if your helmet doesn't keep you safe. Helmet hair beats a fractured skull any day. Once things get rowdy, protection is all that matters. So, can the Montaro Pro justify its hefty price tag? ### The Key Facts - **Technology:** MIPS Spherical - **Certification:** NTA 8776 (for higher impact speeds) - **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) - **Weight:** S: 14.9 oz, M: 16.1 oz (measured) - **Colors:** 7 options - **Price:** $329 ### What Exactly Is MIPS Spherical? MIPS Spherical is a rotational impact protection system. It reduces twisting forces in an angled crash. Unlike traditional MIPS liners, the Montaro Pro uses two layers of EPS foam that move relative to each other, like a ball-and-socket joint. This movement is key. And because there's no plastic liner against your head, the vents and air channels stay open. That means better airflow and comfort. > "MIPS Spherical is like having a suspension system for your brain. It absorbs rotational energy that would otherwise rattle your skull." ### Comfort and Practical Features Giro didn't skimp on comfort. The Roc Loc Trail Air fit system lets you adjust the helmet vertically, keeping it slightly off your head for airflow. The Ionic+ pads contain pure silver for natural odor protection. Nice for sweaty rides. The visor has two positions and stores your glasses. The FIDLOCK magnetic buckle is easy to use one-handed. Plus, there's an emergency info sheet for your details. Thoughtful touches that matter on the trail. ### The Verdict: Is It Worth It? At $329, the Montaro Pro is an investment. But if you ride hard and want top-tier protection, it's worth considering. The MIPS Spherical system is a genuine upgrade, and the comfort features are practical. It's not the lightest helmet, but Giro prioritized safety over weight. For mountain bikers who push limits, that's a smart trade-off. So, hot or not? We say hot. Your head will thank you.
