Based in Amsterdam and sharing creative direction with Marcel Verheijen, the brand takes its cues from vintage, utilitarian, military and workwear clothing — Berryman reimagining functional garments of the 1940s–60s with a leaning toward Japanese streetwear silhouettes, citing Nigel Cabourn, Helmut Lang, Margiela and Raf Simons among his references. Pieces are oversized and loose, and though originally cut for the male body, are marketed as unisex.
Core garments include the AM2-1 Modular Parka with detachable parts, the DM1-1 Japanese Cargo and the WU1-4 Parachute Bag made from military parachutes. Distribution grew from a friends-and-website beginning to Dover Street Market in Tokyo, Singapore and London; a Paris Fashion Week showroom ran in July 2025, and an Amsterdam flagship opened later that year. Esquire and Highsnobiety have praised it; Robb Report named Berryman among the best emerging designers in 2024.
