Weighing approximately 1470 grams, it is relatively light for a modular helmet, which enhances comfort during prolonged use. The helmet's construction from 9K Carbon Fiber adds durability and strength without a significant weight penalty.

Additionally, its dual shell design provides versatility, with ECE 'P' and 'J' certifications allowing it to be used as both an open and full-face helmet. This makes it adaptable to different riding conditions and preferences. On the fit and comfort front, the helmet offers a removable technical fabric liner that keeps you cool, and 3D laser-cut cheek pads that prevent hot spots, promising all-day comfort. The intermediate oval fit should accommodate most head shapes reasonably well.

For visibility and protection, the helmet features an optically correct, scratch, and UV-resistant face shield.

Moreover, the built-in sun shield provides additional eye protection from the sun. The helmet's ventilation system is designed to maintain airflow. The Micrometric quick release chin strap ensures a secure and easy closure, contributing to user safety. Potential drawbacks include its weight, which, at 6 pounds, might feel heavy for some users. Additionally, although it has noise reduction features, user experiences may vary, and it may not be the quietest option available.
