Certification：Our helmets have excellent safety performance and comply with MVSS-218 and DOT ECE 22-R22/05 Safety Standards.

Firstly, our helmet has a multi-layer protective effect: the helmet is a composite shell composed of double-layer carbon fiber and Kevlar, which can absorb impact force to the maximum extent, reduce injury, and protect the head safety! Its weight is also very light, making it more comfortable to wear for a long time, especially for sports that require high flexibility and agility such as cycling and motorcycle racing, equipped with thicker high-density EPS with greater impact toughness; The newly upgraded lining adopts imported COOLMAX fabric and EQRS quick release system, which can be quickly disassembled in emergency situations.

Secondly, the helmet adopts dual lenses, with a horizontal viewing angle of 220 ° and a vertical viewing angle of 80 °, providing a high-definition and wide field of view. The lenses are very sturdy, scratch resistant, and wear-resistant. The camera can be turned on and off in a stepped 3-speed mode, satisfying your various cycling modes!

Thirdly, we have adopted a unique aerodynamic design with a wedge-shaped structure that runs through the airflow, especially the rear wing deflector, which maintains good stability during sharp turns and high-speed driving. The interior adopts a unique circulation channel design, allowing fresh air to circulate continuously inside, making it more comfortable and breathable!

Fourthly, in terms of detail design, the magnetic double D buckle can allow you to fully absorb and free your hands. The eye-catching green EQRS reflective tab can effectively remind you to quickly remove it in emergency situations.

Fifthly, in terms of comfort, our lining is made of space memory cotton, which provides soft and powerful support that conforms to facial curves, gently supporting the cheeks and reducing neck pressure to a greater extent.

Finally, in terms of appearance design, our helmets have a sharp and dynamic appearance, ensuring safe and comfortable wearing, making you look cooler!
