A motorcycle jacket that glows — or rather, one that can. The Lumen Arc is built on a standard moto chassis: pre-curved arms, asymmetric front zip, snap-down collar, CE-rated impact protection at shoulders and elbows. The exterior is a matte black synth-leather with embedded electroluminescent thread woven in circuit-like patterns across the shoulders, sleeves, and back panel. At rest, the patterns are subtle — slightly raised lines you'd mistake for decorative stitching. Activated, they pulse in cool white or amber, drawing the eye from fifty meters.

Lumen Arc is a Tier 2 to 3 street brand that started as a custom shop for courier cyclists and expanded when their light-up designs went viral in underground racing circles. The jacket is popular with night-shift couriers for visibility, with club-goers for aesthetics, and with anyone who thinks looking dangerous and being seen are not mutually exclusive goals.
