Giro Aether Helmet (MIPS)Featuring among the World's most effective protection, the MIPS-assisted Aether Helmet from Giro is a revolution for the road. MIPS works hard to keep your head still in the event of a collision, working alongside a dual-density EPS foam liner that absorbs energy perfectly.On the outside of the helmet, the reinforced, shatter-resistant AURA arch holds the helmet together for full structural integrity in the event of a crash. Meanwhile, extraordinary levels of comfort are provided by a construction focused on breathability, via 11 Wind Tunnel vents that keep you cool, and wicks sweat away from your head quickly. Finally, the CoolFit anti-microbial finish keeps you feeling fresh over longer distances, and eyeglass grippers add a lovely extra layer of practicality, too.Roc-Loc® 5 fit systemHolding it all together, alongside the MIPS system outlined below, is the industry-leading Roc-Loc® 5 fit system. Combining comfort and stability for your head without adding any extra weight to your ride, it keeps close to your skull for unbeatable security, with an easily adjustable fit that can be dialled quickly and easily using only one hand.MIPS (Multi-directional Impact Protection System) The Mips system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head.Rotational motion is a common cause of concussions in oblique hits to the head. In a crash, the Mips system is designed to move slightly inside the helmet to help redirect forces away from the head.Features:11 Wind Tunnel vents with internal channellingIndependent liners with spherical interfaceIn-Mould construction with EPS liner and progressive layeringSix-piece polycarbonate HardbodyRoc Loc 5+ Air MIPSMIPS Spherical Technology - Independent liners with spherical interfaceAURA reinforcing archNanobead EPS foamEyeglass grippersCoolFit anti-microbial paddingShop all MIPS helmets - Click hereBuy Giro Helmets from Chain Reaction Cycles.

Giro Women's Merit Spherical HelmetUsing Spherical Technology powered by MIPS® to give outstanding head protection, the Giro Women's Merit Spherical Helmet will instil the confidence to take your mountain biking to the next level. When riding fast, be it smooth flowing trails to steep and rocky chutes, the Women's Merit Spherical Helmet brings a premium balance of airflow, comfort and optimal head protection. When it all goes a bit wrong, you can trust the Merit to deliver outstanding protection.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 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 burly 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.Cool RidersThe 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 SystemAcross 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.
