Heavy Sun | No. 474Unisex Long Sleeve T-Shirt

We do not compromise on the foundational canvas. Silhouette 3501 is engineered for its exact balance of structural drape and tactile endurance. Designed as an uncompromising, genderless layer, it provides a clean, continuous line that serves as the essential bridge in your daily rotation—substantial enough to hold its shape, yet refined enough to layer seamlessly.

The architecture of this garment is built to dictate form, not restrict it. It features rigorous side-seamed construction, a coverstitched crew collar, and structured 2-inch ribbed cuffs that maintain absolute control over the sleeve break. The interior is rendered strictly tagless, ensuring zero physical friction.

Material Architecture: Solid artifacts are forged from 100% Airlume combed, ring-spun cotton. Heather variants utilize a deliberate 52/48 cotton-poly blend to achieve a specific visual frequency (Athletic and Black Heathers utilize a 90/10 ratio). Operating at a precise 4.2 oz./yd.² (142.4 g/m²) with a 32-single thread count, the fabric delivers a dense, premium finish.

Assembled across our global fabrication network (US and the Americas) 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.
