Be confident in your purchase, we're an Authorized Kali Protectives dealer. How cool is that?!? The Maya 3.0 has been updated with a new vent and a dial retention system. The Maya 3.0 has some big shoes to fill. The Maya has been a Kali Krew favorite and one of our best sellers since its inception. The only real complaint was from our friends in hotter climates, as the previous iteration could get a little warm on those hot Arizona Summer days. So we added an additional vent, which does a remarkable job of increasing airflow. While we were at it we updated the helmet with a dial retention system, including vertical adjust and improved unibody construction for added strength. The Maya 3.0 steps up and, in our opinion, improves on an already great helmet Equipped with our LDL, our proprietary Low Density Layer, the Maya 3.0 provides protection from low-g linear and rotational impact forces. Combined with the high-g impact protection of Composite Fusion Plus, the Maya 3.0 is an enduro helmet designed to protect you from a wider range of impacts. The helmet is shipped with plush Anti-Microbial Pads, flexible Moto-Style Visor, Bug Liner, dial retention system and a Locking Buckle. It is protection made better. WEIGHT: 245 g / 2.6 oz CERTIFICATION:EN 1078, SIZING: One Size 52-57 cm Kali Protectives came from a breakthrough in safety technology - Composite Fusion, a process that bonds the helmet shell and foam enabling us to use a thinner shell, creating a lighter stronger helmet. Lighter and stronger means a safe helmet with less mass attached to your head.
