An A2 jacket crafted from brown-core lamb leather imported from the UK. The design references USAF and aviator jackets from the 1930s to 1940s, while incorporating a pattern structure inspired by classic denim jackets. The lamb leather is tanned with tannin at the base and further treated with tannin during the dyeing process, resulting in a firm yet supple texture. The surface is finished with black pigment over a brown core, allowing the underlying color to gradually emerge with wear, creating a vintage-inspired look over time.
