One K Avance Wide Brim Defender Helmet
The One K Avance Wide Brim Defender Helmet blends advanced technology with elegant design, offering riders enhanced sun protection and premium comfort. Built with a polycarbonate and Advanced ABS composite outer shell, this helmet features an injection‑molded design for strength and durability. The signature wide brim frames the face with a calm, confident line while providing additional coverage from the sun’s damaging rays. Stainless steel mesh ventilation—two front, one back, and two center stripe vents—ensures consistent airflow, and the washable quick‑dry liner keeps riders cool and comfortable.
Certified to SEI ASTM F1163‑23 and CE EN 1384:2023 standards, the Avance delivers top‑tier safety performance. Its comfort‑padded harness includes synthetic suede lining, hook‑and‑loop adjustment, and a Fastex buckle for a secure, customizable fit. Available in Regular/Round and Long Oval shapes, the helmet accommodates different head profiles for a precise, tailored feel. With its blend of protection, style, and engineering, the One K Avance Wide Brim Defender Helmet offers the best of both worlds for discerning riders.
