The HJC i31 Depe MC21 helmet combines lightweight comfort with durable impact protection for everyday street riding. Designed in a Small size, this open-face helmet uses HJC’s Advanced Polycarbonate Compound (APC), blending high-grade polycarbonate with ABS to create a strong, impact-resistant shell while maintaining a lightweight design. The streamlined construction is suited to riders who want broad visibility, practical ventilation, and convenient features for commuting and recreational motorcycle use.
Its Advanced Channeling Ventilation System (ACS) promotes full front-to-back airflow, helping move heat and humidity away from the rider’s head. The Pinlock-prepared HJ-43 visor provides 99% UV protection and includes an anti-scratch coating, while the compatible anti-fog lens preparation helps support clear vision in changing conditions. An integrated dark smoke HJ-V12 sun shield is installed and offers improved peripheral vision, effective sunlight blocking, and reduced eye strain. The sun shield is also anti-fog and anti-scratch coated.
Removable, washable crown and cheek pads help simplify cleaning and long-term helmet care. The interchangeable cheek pads can be used throughout the available size range for a more personalized fit, while built-in glasses grooves accommodate riders who wear eyewear. The moisture-wicking, quick-drying interior helps improve comfort during extended rides. Manufactured by HJC and supplied under vendor part number JP45NUS4321V, the i31 Depe MC21 is designed to fit riders requiring a Small-size HJC i31 helmet.
