Not only does the ATLAS 4.0 Core full face motorcycle helmet provide you with a true stealth-fighter appearance for the road, but it also boasts the classic stealthy matte black finish that lets the iconic ATLAS contours do the talking. Making it one of the best choices to enhance your protection, and with the addition of the new RHEON headliner, safety is improved even further. Its non-Newtonian fluid properties offer targeted energy dissipation against impact and rotational forces, all powered by reactive polymers. - Comfort was a key aspect of the ATLAS 4.0 design process and our brand-new tailor-made cheek pads and headliner offer you the comfiest riding experience in an ATLAS to date. Our multi-layered foam of different densities and soft moisture-wicking outer fabric provides you with a comfortable and secure fit. The new ATLAS 4.0 Core is the quietest Core yet due to the removal of two of the top vents and sound dampening ear inserts which can be placed in the helmet to further reduce sound around the ears. - The ATLAS 4.0 is Rurocs quietest motorcycle helmet ever but why not improve the functionality and entertainment and upgrade it to a Bluetooth motorcycle helmet with our Shockwave Bluetooth insert (sold separately). The ATLAS Shockwave is easily installed with a seamless fit into the rear of your helmet. The ATLAS Shockwave now has a 60% smaller mic and low-profile speakers that deliver high-quality audio with rich bass for 8 hours of playtime with a USB-C rechargeable battery. - The ATLAS 4.0 Core can be transformed and customised with our wide range of helmet visors. The helmet comes with a pre-installed clear visor for road use and a secondary tinted visor for track use only. All our visors are compatible with Pinlock inserts that can easily be installed for anti-fog protection (available separately).
