This jacket from Japanese leather masters Double Helix is the Classic 1930's inspired by Leather "Sports Jacket" style jackets around the 1930's. The cut has been updated to a more form fitting modern cut. Jacket started to feature zippers instead of button front fastening around this period and the 1930's features a unique "gem" shaped zipper puller that hives it a vintage original feel. The insertion is also quite special as they have to drill holes in the leather to attached the zipper to the hem of the jacket.Made from a premium 1.3mm Japanese vegetable tanned, tea core horsehide leather we love this take on a 1930's inspired jacket. The tea-core leather will start of as black and will contrast with brown as the jacket ages in high wear areas.- Classic 1930's inspired Jacket.- Vegetable tanned tea core Japanese horsehide leather.- Pigment Dyed black oiled finish- Semi-Aniline Finish.- 1.3mm thickness.- Left chest pocket with zip.- Buffalo horn button cuffs.- Angled hip pockets.- Inside pocket.- Brass waist adjusters.- Waldes Zipper.- 100% Cotton lining.- Made in Japan.
