Tuna Sashimi Donburi | No. 407Unisex Pullover Hoodie

Structural Specifications: The Pullover Architecture (Build 3719)

The definitive heavyweight layer. Build 3719 is engineered for thermal retention and structural isolation. Designed as an uncompromising spatial barrier, it provides a dense, continuous line that anchors the daily rotation. It does not merely drape; it encompasses, providing substantial physical weight without sacrificing minimalist geometry.

The architecture of this garment demands absolute shape retention. It features rigorous side-seamed construction, structured ribbed cuffs, and a calibrated spatial volume designed to maintain its rigid form through continuous seasonal wear. The exterior plane provides a flawless, consistent surface for our visual discipline, ensuring the artifact remains a permanent fixture of your uniform.

Material Architecture: Solid artifacts are forged from a dense 52/48 integration of Airlume combed, ring-spun cotton and structural poly-fleece. Heather variants shift to a deliberate 60/40 ratio to achieve their specific visual frequency. Operating at a heavy 6.5 oz./yd.² (220.4 g/m²), the interior fleece provides a highly effective thermal boundary while maintaining a stark, refined exterior finish.

Assembled across our global fabrication network under strict ethical and environmental protocols, ensuring every artifact meets the ichinichi standard before it is commissioned for your wardrobe.

Every ichinichi piece is made on demand, only after it is ordered. This keeps us out of the cycle of excess inventory and unnecessary waste.

Your garment is produced specifically for you, with a typical 3–4 day fabrication period before shipping. It is a slower, more deliberate model, but one that lets us make only what is needed and keep the process focused on quality rather than volume.

Nothing is pulled from a stockpile. Your piece is made for your daily rotation when you commission it.

ichinichi ships worldwide, with complimentary shipping on every order.

To reduce unnecessary transit and support our on-demand model, we work with a decentralized production network across the US, EU, UK, and Japan. Whenever possible, your piece is produced at the facility closest to your destination.

After a typical 2–5 day fabrication period, most orders arrive within 3–6 days, depending on region. Delivery times may vary internationally, but each order is routed through the nearest available production hub.
