Final sale — no returns or exchanges. Inspected return/exchange in unworn, as-new condition.

A refined take on the late-1950s Café Racer, this slim J-100 strips the design down to its essentials while adding subtle upgrades. The jacket delivers a clean, sharp silhouette with accordion pleats for mobility, a slanted chest pocket, and a discreet wind flap. Built from Ferrara oil-wax horsehide, it combines density, flexibility, and sheen in a sleek racing profile that feels as fast as it looks.

Please scroll down to find the detailed measurements.

  • Emerging from the minimalist Café Racers of the late 1950s, the J-100 stripped away belts and epaulets for pure speed and function. This version keeps that spirit, refined with a slimmer waist, single chest pocket, and streamlined fit for motion and efficiency.
  • Crafted from 1.3mm Ferla oil-wax horsehide on a Polish base. Overdyed black through the core, it develops a rich oil-film patina and warm natural gloss. Soft yet dense, it ages into a uniquely personal finish.
  • Cut slim with a cinched waist and streamlined body. Accordion pleats at the back ensure ease of movement, while the cropped length and narrow lines sharpen the silhouette.
  • Hardware: Upgraded IDEAL main zippers with occasional CONMAR chest zips.
  • Details: Wind flap behind front zip, slanted chest pocket, and inner pocket.
  • Construction: Accordion pleats at the back for mobility, minimalist Café Racer layout without waist tabs or handwarmer pockets.
  • Weight: Approx. 1.7 kg
