The BEAMS PLUS military trousers are crafted from twill weave fabric, commonly known as "weapon cloth," which uses double warp and weft threads. This high-quality material features strong, twisted yarns with reduced fuzz, achieving both a dry texture and a glossy surface.

The design is based on USMC herringbone trousers from the 1940s, and a special washing process gives the fabric a vintage feel. While many ivy-style chino pants exist, these trousers offer a rugged military aesthetic with a classic, thick silhouette.
