We couldn't pass up this collaboration between Ichi and TAION. This twill overcoat set comes with a removable inner down vest that provides an extra layer of warmth and protection on colder days and a stylish outer layer on those in-between days. Details include a stand collar, a fully buttoned front with a hidden placket, two front flap pockets, buttons at the cuffs, and an inverted back pleat.

TAION (meaning "latent heat") is a high-quality and highly functional Japanese inner down brand. Their fabrics consist of high-density taffeta and nylon that are treated to be water-repellent and stain-resistant.
