Lightweight All-Rounder: Size M weighs approximately 215–240g, making it nearly 100g lighter than entry-level helmets. It stays comfortable even during long rides, preventing pressure on the head and neck strain, and is suitable for both road and mountain biking.

Smart Ventilation System: 9 large vents on the front + smooth airflow guidance on the top + 6 exhaust vents at the rear, allowing heat and moisture to dissipate quickly during high-speed riding.

High Quality: High-density EPS foam interior + built-in plastic sub-structure reinforcement on top; the reinforced frame reduces the risk of breakage from impact.

Octo Fit Precision + Washable Liner: Fine-tuning knob + floating up-and-down system, allowing you to adjust the support position vertically before tightening; the quick-drying liner is treated with an antimicrobial finish, and all components are removable and washable.

Sleek Aero Look: The glossy black version is the most versatile and works for any occasion; the streamlined side design makes your face look smaller, and the two sizes—M and L—fit head circumferences ranging from 52 to 62 cm.
