The AVIO is Bollé's ultimate high-performance road helmet. The fastest cycling helmet ever designed by the brand has it all. Ultra-lightweight thanks to its EPS design, lightweight in-molded components and optimized fit system, it features MIPS® AIR, MIPS®'s most lightweight brain protection system. Super ventilated, the AVIO is designed to align both deep internal channeling and large front vents with small exhaust ports that create low pressure at the rear of the helmet for extra air circulation. Developed to make you faster with cutting-edge aerodynamics, the AVIO has an optimized low-profile shape and is equipped with the AVID Aero Progressive EPS to direct airflows and manage impact energy. Conceived to reduce drag thanks to its Kamm Tail at the rear, the AVIO is all about details with an Opti-Dock designed to securely hold all-sized sunglasses and even a ponytail compatibility. A new generation of helmets with no compromise.Features:Mips® safety system:- The Mips® safety system is a low-friction layer inside the helmet. Generally located between the padding and the EPS foam protective layer, it allows a multi-directional movement of 10-15mm on certain angled impacts, intended to help reduce rotational force to the head. It is engineered to work flawlessly with the helmet´s design without compromising either the comfort, the ventilation or the fit. There are different Mips® systems, but all consist of a low-friction layer between the helmet and the head that provide extra protection to your brain so you can focus on your activity, light-hearted.Click-to-fit system:- Our Click-To-Fit™ system allows you to fine tune the fit of your helmet easily and quickly. Our rubberized adjustment wheel lets you tighten or loosen the helmet effortlessly, even with your gloves on.
