| MIPS® | - MIPS®: the best brain protection system on the market, Mips® is a patented system designed to protect you from falls, especially from side impacts, by reducing the rotational force transmitted to the brain. |
| ABS | This best-known security technology consists of two separate pieces that are glued together. On one side, the hard ABS plastic external shell provides the Ski helmet with considerable durability, while on the other side, the internal part of the helmet made of hard EPS (but deformable) foam manages shock absorption and diffusion. |
| AVID PROGRESSIVE EPS | Technology offering effective protection in all types of low, medium and high-impact collisions by ingeniously distributingEPS impact zones, reducing certain areas and increasing those that are necessary. This process enlarges the interior space for better ventilation and air circulation while maintaining optimal protection and making it lighter. |
| CLICK-TO-FIT™ | System for quick and easy micro-adjustment of the helmet fit. The rubber adjustment dial allows the helmet to be tightened or loosened effortlessly, even when wearing gloves! |
