The ALTIOS' hybrid suspension system, composed of a mesh panel and expanded polystyrene liner, makes this helmet extremely lightweight and comfortable to wear. Thanks to this innovative design, the helmet "levitates" above the head for a near-weightless feeling. The space between the head and the liner allows for effective ventilation with the Climate Control System. Durable ABS shell. This helmet is very ergonomic, adapting to almost any head shape and offers two options for attaching a headlamp: a removable system-compatible mount, or clips.
