From fast flowing trails with plenty of pedalling through to steep and technical trails where gravity does the work, the Merit Spherical Helmet offers the ideal balance of comfort, airflow and burly crash protection when it all goes wrong.
Comprehensive head protection comes via a mix of technologies, including Spherical Technology™ power by MIPS® brain protection systems and Giro's Progressive Layering™. The in-mould shell features a shock-dissipating EPS foam liner, and here the Progressive Layering™ focuses on providing separate inner and outer layers to manage both high and low-speed impacts.
To the outside, the polycarbonate shell offers a durable and tough layer to resist knocks and bumps from those low hanging branches and overgrowth along the trail. This coverage extends fully to the bottom for maximum coverage.
Spherical Technology powered by MIPS® (Multi-Directional Impact Protection System)
As you'd expect, all Giro helmets are designed to not only meet but also exceed stringent safety standards. The ball and socket Spherical Technology, powered by MIPS, allows the outer liner to rotate around the inner liner during a crash, ensuring you enjoy an extra level of brain-protecting technology, designed to redirect energy and provide more protection in certain impacts.
This system also eliminates contact of plastic and slip planes with your skin, boosting your overall riding comfort.
The 15 Wind Tunnel™ vents suck cool air inside, where it's then channelled across the head for optimal airflow. It keeps you brilliantly cool as the trail demands your full attention. This rush of airflow is also complemented by the Ionic+™ padding. With its permanent anti-microbial performance you'll enjoy the freshness and itch-free comfort whenever you ride.
Roc Loc® Trail Air Fit System
Across rough terrain, you don't want your helmet moving about. And in a crash, a secure helmet is a safer helmet too. With the Roc Loc® Trail Air Fit System, you can be sure you always get the adjustment comfortable and secure. It allows for quick and precise single-handed adjustment with the rear dial as well as fore-aft tilt adjustment.
