100% Altis Helmet

Smartshock is 100%'s proprietary rotational protection system. It uses 11 independent points of movement between the helmet shell and the liner to absorb and disperse impact forces, similar to other rotational systems, but designed specifically to manage both low and high-speed impacts.

While it is optimized for the specific demands of gravel—balancing airflow with robust protection—it is a versatile half-shell helmet. It works perfectly well for road cycling or light trail riding, though it lacks the extended rear coverage found on dedicated mountain bike helmets.

The Altis features 14 ventilation ports designed to channel air efficiently across the scalp. It provides significant airflow, making it a strong choice for high-intensity efforts and warm-weather riding where overheating is a concern.

Yes, the moisture-wicking liner is fully removable and washable. This is a key feature for gravel riders who often spend long hours in the saddle and want to keep the helmet fresh and odor-free.

The adjustable ratcheting system is designed for precision and stability. Once tightened, it provides a secure, consistent fit that prevents the helmet from shifting or bouncing, even when you are navigating washboard gravel or bumpy descents.
