Exposed seam construction across the back panel. What most brands hide, D.HYGEN makes central. D.HYGEN builds tension into basic silhouettes. This t-shirt looks minimal from the front - clean black cotton, simple crew neck. Turn it around and the philosophy reveals itself: the back features visible seam construction, deliberately exposed rather than hidden. The seams are structural notation, mapping the garment's architecture on its surface. What most brands conceal inside linings, D.HYGEN makes the focal point. Two adjustable straps with metal buckle hardware hang from the lower side seams - industrial punctuation on soft cotton. The cuffs are raw-edged, intentionally unfinished. The cotton has a smooth, premium hand with a matte finish that absorbs light rather than reflecting it. Osaka craftsmanship applied to a t-shirt - meticulous pattern-making, deliberate seaming, the refusal to disguise how a garment is made. Details Material: 100% cotton with matte finish Construction: Visible seam construction on back, raw-edge cuffs, pullover closure Hardware: Adjustable side buckle straps with metal hardware at lower hem Origin: Made in Japan Care: Machine wash cold. Raw edges will soften with wear - this is intentional. Soft cotton. Industrial hardware. The tension is the design.
