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 body is made of imported ABS material, which has good impact resistance and vibration resistance, which can effectively reduce the impact force of the helmet shell on the head during collision, thereby improving the protective effect of the helmet; Equipped with thickened and 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, with a patented magnetic suction design, you can easily remove the lens in just one second, bidding farewell to the traditional lens disassembly troubles. The unique lens design features a vortex generator, which suppresses the flow separation of surface fluids and effectively improves aerodynamic performance, thereby achieving the effect of reducing storms; The lens has a 220 ° large viewing angle and a wide field of view, making your riding safer. It also features explosion-proof, UV resistant, fog resistant, and scratch resistant features. The lenses can be adjusted from multiple angles and can activate various modes such as daily cycling or travel.

Thirdly, we adopt an innovative circulating air duct design. In addition to the conventional mouth air outlet, we also specially designed the top air inlet and tail air inlet, especially the unique top ventilation design, which can effectively increase or reduce ventilation, making your riding more comfortable and breathable.

Fourthly, the unique aerodynamic bulge and depression design can effectively reduce wind obstruction, balance airflow, and make your wearing more stable and comfortable!

Fifthly, in terms of detail design, we have added storage slots for wired or Bluetooth earphones to the helmet lining to enhance comfort. The magnetic dual D-buckle allows you to fully absorb and free your hands. The eye-catching EQRS reflective pull tab can effectively remind you to quickly remove it in emergency situations.

Sixth, in terms of comfort, our inner lining is made of space memory cotton, which conforms to the curves of the face with soft and powerful support, gently supporting the cheeks and reducing neck pressure to a greater extent.

Finally, in terms of appearance design, we adopt a streamlined design, making it cooler and more stylish for you to wear!
