Ventilated aerodynamic Mips bike helmet. Color: Prism Green - Radium Yellow - Size: L - The new Centric Plus helmet by Scott was designed and developed for world-class road and mountain bike racers. Scott leveraged their extensive aerodynamic expertise to make one of the lightest and best ventilated helmets in its class - the Centric Plus helmet. This was achieved through optimization of airflow on both the outside and the inside of the helmet. Mips Air layer provides the benefits of a Mips Brain Protection System and features a unique construction to further enhance ventilation. - Range of use: Biking - Construction: In-Mold Technology, Polycarbonate Micro Shell - Fit: Scott ́s top of the line Halo Fit System 270 with rubber dial provides ease of adjustability and unparallelled comfort. Easily find the perfect height of the rear ergonomic cradle while the helmet is on your head and dial in the perfect pressure using the beautifully engineered micro adjustment dial. The result is the best feeling helmet ever, a helmet which adapts to your head shape and leaves you feeling secure and focusing on the ride. - Mips Brain Protection System: Mips stands for Multi Directional Impact Protection System. The system, which was devised by Swedish doctors and engineers, was designed to provide protection even when the human brain is subjected to strong rotational movements in a multi-directional impact. Helmets without Mips technology also offer protection - but only in linear impact scenarios, i.e. when the head hits an object/ground straight on rather than at an angle - which is negligibly rare in practice. - Optimized Ventilation - Lightweight - Aero Optimized - Weight: 220 g The Centric Plus by Scott is available in three sizes: - Size S: Head circumference 51 - 55 cm - 20 - 21.75 in - Size M: Head circumference 55 - 59 cm - 21.75 - 23.25 in - Size L: Head circumference 59 - 61 cm - 23.25 - 24 in Note: The helmet in the colour Nitro Purple is not matt (as on the product picture) but metallic glossy. - Material: Polycarbonat
