One of the hardest designs ever to hit the streets. Layered in a reptilian black, it oozes nitro pink and green through a fearsome grill that will have the opps thinking twice before acting up.The AT4.0 rocks the superb ECE 22.06 safety certification and the latest DOT standard providing you with enhanced safety and comfort, while you take to the streets as The Batman. With our new premium sweat-wicking cheek pads that contain multiple layers of multi-density foam, the AT4.0 has never felt comfier. In case you want to wash your helmet liners you can fully remove the foam layers from inside the cheek pads to further improve the longevity of the helmet liners. The headliner of the AT4.0 features integrated RHEON technology for better impact resistance. RHEON is a reactive polymer that is a non-newtonian fluid which works to reduce rotational and linear impact forces. It sits between the headliner foam and the EPS to act as an extra layer of protection offering targeted energy dissipation in the case of an accident.The newly engineered carbon fibre shell offers a more streamlined and quiet experience due to the removal of several vents that were located on the top of the helmet. Now you will just find a chin vent and front top vent, both of which are fully adjustable so you can control your helmet climate with a total of 4 airflow settings for enhanced temperature control in both hot and colder environments.The AT4.0 is Ruroc's 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 AT Shockwave is easily installed with a seamless fit into the rear of your helmet. The AT 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 AT4.0 La Catrina can be transformed and customised with our wide range of helmet visors. We offer 7 additional coloured visors that are easily changeable with our quick release thumbscrews. 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).
