The outer and lining fabrics use "ECOPET PLUS," an ultra-lightweight material developed by "TEIJIN" known for its wrinkle resistance and water-repellent properties. Furthermore, the lining incorporates "OCTA CPCP," which is characterized by its high heat retention and light weight, resulting in a highly functional finish. The design is a track jacket featuring a bold asymmetrical paneling. It incorporates classic details such as raglan sleeves, a stand-up collar, and a full zip, while also embracing a 90's-like aesthetic with features such as wider armholes and a rounded body, typical of the brand. Although it appears to be a retro-designed track jacket, the use of "TEIJIN's" high-tech materials makes it a highly functional piece.
