The Merit Spherical is the ideal choice for fast, flowy trail riding and hard pedaling. With Spherical Technology, it offers more comprehensive performance and protection with the combination of a MIPS brain protection system to redirect rotational impact energy. Plus, separate inner and outer liners featuring Progressive Layering help manage high- and low-speed impacts. Massive Wind Tunnel vents are combined with channels in the EPS foam liner, creating amazing airflow through the helmet to exhaust heat out, even on long, hot climbs. Fit and stability adjustments are fast and easy with the Roc Loc Trail Air fit system, and plush Ionic+ padding provides exceptional sweat absorption while combating odor with permanent antimicrobial performance.

From the Enduro World Series to Red Bull Rampage, top riders demand the Giro Insurgent Spherical and the confidence it delivers. Our engineers maximized the intake points for cool, fresh air, resulting in cooling power 50% more efficient than the Disciple MIPS. A lightweight, soft-touch, and absorbent pad set includes two different cheek pads with each of the three sizes, allowing for a customizable fit, which are secured via a directional snap system allowing for easy removal in case of a crash. At 1,040 grams in size M/L, the Insurgent is 200 grams lighter than the Disciple MIPS despite additional features including the advanced protection performance of Spherical Technology. Insurgent Spherical utilizes a pair of different density EPP and EPS foam layers that work like a ball and socket to redirect impact energy in a crash. Additional features include a patent-pending Flex Gasket along the lower edge of the helmet, designed to reduce the role a helmet can play in certain collarbone impacts, tool-free breakaway visor bolts with integrated Allen key receiver for easy removal, and a central visor bolt hole, which does double-duty as the ideal mount for P.O.V. action cameras. - SPHERICAL TECHNOLOGY, POWERED BY MIPS — Spherical Technology's ball-and-socket design, powered by MIPS, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin. - OPTIMIZED FRONT INTAKE VENTS — Giro engineers designed precise placement and shape of intake vents to optimize cool air flowing over riders' heads. - MAXIMIZED REAR EXHAUST VENTS — Our complex Wind Tunnel venting system allows hot air an easy escape route from the rear of the helmet. - BREAKAWAY VISOR BOLTS — Tool-free breakaway visor bolts are engineered with an integrated Allen key receiver for easy removal and replacement in case of crash. - DIRECTIONAL SNAP SYSTEM — In case of emergency, cheek pads are easily removable without disturbing the rider's head and neck position. - PATENT-PENDING FLEX GASKET — The zone along the lower edge of the helmet is designed to allow some flex, reducing the role a helmet can play in certain collarbone impacts. - STEALTH CAMERA MOUNT — The central visor bolt hole does double duty as an ideal location for mounting P.O.V. action cameras.

LIGHTER, COOLER, SLEEKER, PLUS ALL THE ADDED PROTECTION OF SPHERICAL TECHNOLOGY POWERED BY MIPS® AND OUR NEW DRYCORE™ SWEAT MANAGEMENT SYSTEM: THE ARIES SPHERICAL IS LIKE NOTHING BEFORE. STRUCTURAL INTEGRITY The proprietary AURA II Reinforcement Arch makes everything possible. These shatter-resistant, translucent twin bridges run throughout the helmet, providing structural integrity without adding unnecessary weight. Aries’ ultra-low weight (~5% lighter than Aether), impressive cooling power and sleek, compact shape would not be possible without AURA II. SPHERICAL TECHNOLOGY This unique ball-and-socket design, powered by Mips®, helps redirect impact forces. Spherical Technology also boasts more comfort, improved airflow, and Progressive Layering (which mates two densities of EPS foam to address a wide range of impact energy). The results are clear: independent authority Virginia Tech has rated Aries #1 in reducing the risk of injury. It’s the best performing helmet they’ve tested so far – even out-performing much bigger, bulkier helmets at reducing risk. COOL COMFORT Deep internal channels connect with Aries’ massive front and rear vents. This system provides a path for cool air to flow over the rider’s scalp and exit the rear, taking excess heat with it. Aries outperforms our previous cooling benchmark, the Aether, with a 2.3% improvement in cooling efficiency. STREAMLINED SPEED When it comes to going fast, smaller truly is better. To craft Aries, we focused on reducing the frontal surface area to eliminate more drag. Add in tiny details like chamfered edges on the AURA II, and meticulously engineered internal channeling that actually speeds up the air as it exits the helmet, and Aries emerges as the climbing helmet that doesn’t sacrifice speed, reducing aerodynamic drag by 4% over Aether Spherical. Aries also debuts our revolutionary DryCore™ sweat management system. A soft, silicone bead is hidden within the plush brow pad that redirects sweat away from the forehead and to the temples, where it can evaporate more easily. LIKE NOTHING A helmet that feels like it isn't there: the all-new Aries™ Spherical is like nothing before. Its sleeker form and lighter weight (only 270 grams in size medium, CE certification), deliver sensational comfort and cooling power. Spherical Technology™, our ball-and-socket design powered by Mips®, adds protection by redirecting energy away from the brain in certain impacts, and Progressive Layering with dual densities of Nanobead EPS foam adds more comprehensive energy management. 24 Wind Tunnel vents are maximized by the AURA II Reinforcement Arch, while a plush DryCore™ brow pad manages sweat and combines with a network of intricately engineered deep internal channeling to elevate comfort. From the proven reliability and adjustability of the Roc Loc® 5+ Air fit system, to full lower hardbody coverage to enhance durability, to the meticulous production quality, the Aries is state-of-the-art performance, protection, and style.

The all-new Liv Rail Mips Helmet features the latest in high-performance off-road technology. Purpose-built with extended bottom shell design for additional back-of-head coverage plus the Integrated Mips Air Node technology to offer the best rotational impact protection. The 4-position rear height adjustment provides an optimal secure fit every time, sweat-blocking brow pads and an anti-microbial strap bring comfort even when things heat up. The ultimate helmet for riders who demand the perfect combination of comfort, fit, and increased protection. MIPS® The Mips® BPS (Brain Protection System) is designed to add protection in helmets against the rotational motion. The rotational motion is a combination of rotational energy (angular velocity) and rotational forces (from angular acceleration) that both affects the brain and increases the risk for minor and severe brain injuries. Mips® BPS has been scientifically proven to reduce rotational motion when implemented in a helmet by absorbing and redirecting rotational energies and forces transferred to the brain.
