This vintage jacket was made in the late 1930s-early 1940s by Levi Strauss. Though missing the label (which would read “Climate Sealed / Jacket / Wind and Water / Repellent / Treated with Zelan / Levi Strauss & Co”), it is an unmistakable piece. It has a distinctive cut and equally distinctive detailing, with reinforced shoulders, D shaped zip pockets (with chain Talon zippers), underarm ventilation grommets, elasticized cloth panels on the waistband, a U shaped back yoke with a center pleat, curved reinforcement stitching under the collar and green Talon “sunburst” zipper (the color covers the Talon text on the stopbox on the front, it is visible on the back). This jacket has been reproduced by Levi’s under the LVC line three times, once a few years back, with a secret society style “Globus Hortus” graphic on the back, once in black with patches and more recently in red with simplified details (no back pleat, no grommets).
