KPLUS Sigma Helmet
KPLUS Sigma Helmet
The SIGMA road bike helmet is a special presentation of KPLUS's 10th anniversary! SIGMA comes from the "sum" of the mathematical symbol Σ, which perfectly embodies KPLUS's ten years of exquisite craftsmanship and core concepts.
The SIGMA design not only has the unique mark of KPLUS's 10th anniversary, but also has a ground-breaking arrangement of air holes and ventilation slots inside the cap shell. After countless wind tunnel experiments and precise adjustments, we pursue the ultimate air flow and heat dissipation performance. The streamlined design of the air guide groove allows the airflow to pass effectively while maintaining excellent heat dissipation performance. SIGMA helmets strike the perfect balance while maintaining basic weight and safety.
