    11oz Military Serge Western Shirt HSH-454-BRN – Brown

    IRONHEART

    US$375.00
     
     

    The Iron Heart IHSH-454-BRN is an 11oz Japanese military serge Western shirt in brown, combining the durability of traditional military fabrics with Iron Heart's classic slim-fitting Western silhouette. Inspired by the high-density cotton serge used in French M-47 military cargo pants from the 1950s, the heavyweight twill fabric features a distinctive ridged texture, offering substantial construction while remaining comfortable and breathable for everyday wear.

    Made in Japan from 100% cotton, the shirt features Western-style front and back yokes, flap chest pockets, a curved hem and heavy-duty snap fastenings. The brown fabric is reactive-dyed in both warp and weft for excellent colour retention, complemented by tonal stitching, contrasting pearl snaps and subtle yellow internal bobbin thread. A rugged alternative to denim and flannel, designed to be worn on its own or layered in cooler weather.
