Giro Synthe MIPS Aero Road Helmet - 2017
The Synthe is 16% faster and 2% cooler than the Aeon, 13% lighter than the Air Attack and has a sleek, aesthetic design for high efficiency. Elaborate internal channeling and 19 gigantic vents provide excellent flow-through and take cooling power to new levels. Perforated side panels draw more air inside the helmet for consistent airflow at any speed and help reduce drag. Roc Loc Air retention system is fully adjustable and creates a gap between the forehead and the inside of the helmet to further enhance the cooling equation. There are eyewear docks in the side panels for stashing your sunglasses, and a comfortable fit is achieved, thanks to the X-Static internal padding, Slimline webbing and an ultra-light buckle. The Synthe MIPS is the most comprehensive road helmet on the market.
Multi-Directional Impact Protection System (MIPS) is a technology composed of three main components: an interior foam liner, a Low Friction Liner and an elastomeric attachment system between them. In an angled impact, the elastomeric attachment system stretches to allow the interior foam liner to rotate independently around a rider's head and redirect energy. The system moves only a few millimeters, but Giro's testing has shown that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to the brain in certain impacts.
