Syntax is a race-cut helmet packed with technology. Thanks to its aerodynamic shape and perfect ventilation, it performs equally well on flat and hilly terrain – simply a perfect all-rounder. What’s more, thanks to the Roc Loc 5 fit system, which in the MIPS version also integrates the MIPS slip layer, it sits luxuriously on the head.

MIPS (Multi-Directional Impact Protection System) provides increased protection against rotational forces acting on the head. All Giro helmets are designed to absorb as much energy as possible on impact and meet the current European standard: EN 1078. The aim of the new MIPS technology is to eliminate rotational forces that act on the head in the event of a fall. On impact at any angle, the MIPS system allows the EPS shell of the helmet to rotate independently around the rider’s head. Although this movement is only a matter of a few millimetres, we believe that MIPS technology significantly reduces the amount of rotational force that could otherwise be transferred to the brain.
MIPS is a low-friction insert between the EPS shell (the body of the helmet) and the internal padding. In the event of an angled impact (for example, if your head catches on a branch), the EPS shell of the helmet rotates a few millimetres over the MIPS layer, helping to protect the head and brain from a sharp rotational jolt.
Science and soul. They might seem like two disparate entities - but through the 30-year history of the Giro brand, they have been brought together in equal measure. Giro benefits from world-class resources. Based in Santa Cruz, California, it's an action sports paradise - incredible waves for surfers, endless singles for bikers and coastline-lined roads for roadies.
At Giro's headquarters, you'll find over 50 different helmet testers, several 3D printers, a custom wind tunnel, and even a Therminator test head equipped with thermal sensors to test helmet venting and hole placement. Giro has a lot of products in many categories, from helmets to gloves to trunks. But each one was born out of a desire to enhance your riding experience.
