The Essential Form. A garment stripped back to its purest purpose. This is not a fragile undershirt; it is a dedicated outer layer built from open-end yarn, creating a dry, textured hand-feel that recalls vintage streetwear. The tubular construction eliminates side seams for an unbroken, comfortable fit that resists twisting. A quiet staple designed to carry the weight of the symbol it bears.
The Details
- Dry Touch: Crafted with Open-End Yarn for a crisp, textured finish that holds its shape.
- Classic Weight: 5.0–5.3 oz/yd² (170–180 g/m²) fabric—substantial enough for daily wear, breathable enough for motion.
- Seamless Body: Tubular fabric construction creates a continuous silhouette with no side seams.
- Durability: Taped neck and shoulders with double-stitched hems for reinforced longevity.
Material Composition
- Solid Colors: 100% Cotton.
- Heather/Grey Variants: Cotton/Polyester blends for texture and resilience.
Texture Notes
- Natural Variance: The "Natural" colorway features subtle dark speckles—a hallmark of unbleached, organic character.
- White: Due to the density of the fabric, the White variant presents as a rich, warm white rather than a chemically bright white.
The Process Made for the Individual. To minimize waste and reject the culture of overproduction, this garment is crafted specifically for you upon order. This deliberate process ensures that every piece serves a purpose before it even leaves our studio.
