Fastened | No. 199Unisex T-Shirt

The definitive baseline of the ichinichi catalog. Build 3001 is engineered as our primary structural canvas. Designed as an uncompromising, genderless silhouette, it delivers the exact balance of physical endurance and deliberate drape. It is not designed to be invisible; it is crafted to serve as the heavy, continuous foundation of the daily rotation.

The architecture of this garment demands absolute shape retention. Engineered with rigorous side-seamed execution and pre-calibrated for dimensional stability, it is built to maintain its stark geometry through continuous environmental cycles. The exterior plane is highly optimized to receive our visual discipline, ensuring every typographical and structural element binds permanently to the form.

Material Architecture: Solid artifacts are forged entirely from 100% Airlume combed, ring-spun cotton. The Ash variant introduces a highly deliberate 99/1 cotton-poly integration. Heather variants shift to a 52/48 ratio to achieve a specific visual frequency, while Athletic and Black Heathers utilize a 90/10 structural blend. The unique Heather Prism tones are calibrated at a 99/1 ratio. Every variant delivers a dense, premium 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.

We reject the bloated cycle of mass retail. Every ichinichi artifact is engineered with absolute intent, meaning your garment does not exist until the exact moment it is commissioned.

By operating on a strict, on-demand fabrication model, we eliminate the physical waste and environmental friction of the fashion industry. This process requires a deliberate 3–4 day lead time before shipping. It is a slower, uncompromising system designed to ensure structural perfection and zero excess inventory. Your piece is not pulled from a static stockpile; it is forged strictly for your daily rotation.

The ichinichi discipline is a universal architecture. We commission and deliver artifacts globally, providing complimentary transit on all orders, regardless of destination.

To maintain our strict zero-waste philosophy and eliminate unnecessary carbon friction, we operate a decentralized fabrication network with localized hubs across the US, EU, UK, and Japan. Your garment is engineered at the facility closest to your coordinates. Following the deliberate 2–5 day fabrication period, please allow 3–6 days for localized transit. Global deployment times vary by region, but every piece is routed with absolute efficiency.
