The Spiri Two is a multi-award winning MTB helmet with a precise fitting system and integrated tail light. In the K-Star version, the helmet has a 360° reflection for best visibility in low light conditions.
By embedding retro-reflective particles in the production process of the helmet's upper shell, K-Star stands for the most effective and durable retro-reflection in the helmet sector at present. The full-surface reflector offers 360° visibility without sacrificing design options for the helmet decors. K-Star helmets guarantee maximum visibility for cyclists in the dark. Every beam of light that hits the helmet is reflected back directly to the light source by the millions of tiny glass beads on the helmet's upper shell. The helmet appears brightly shining with impressive intensity.
In the maxShell manufacturing process, almost the entire EPS inner shell is covered by the outer microshell, even up to the ventilation openings (maximum microshell coverage).
The Quickstopp system in the middle of the helmet allows quick adjustment of the strap length and prevents the strap from slipping from one side of the head to the other.
The patented Quicksafe system ensures simple and precise adjustment to the individual head shape and guarantees maximum wearing comfort and safety.
