Y31 Ultra Heavy Organic Long Sleeve Sweatshirt, Midnight Black [In stock]

Model size: 6ft, wearing medium

Weight with intent. Structure with edge.

The Y31 isn’t just another crewneck — it’s a menacing silhouette, built from the ground up to impose presence. Crafted from 100% organic cotton at 520GSM, this piece is knit on precision Korean machines to achieve an ultra-dense face and luxuriously soft looped interior.

Designed with a standard crew neckline and clean waist rib, the standout feature is its angular V-cut ribbed cuffs — a subtle architectural detail that sharpens the entire silhouette.

Key Features:

• 520GSM ultra-heavyweight organic cotton fleece

• Knit on advanced Korean machinery for refined texture and structure

• Smooth outer surface + soft looped fleece interior

• Boxy fit with wide, structured shoulders

• Standard crew neckline with deep ribbing at hem

• Signature V-cut rib cuffs — aggressive and tailored

• GOTS-certified cotton + OEKO-TEX® approved dye

Care Notes:

Wash cold on delicate. Lay flat to dry. Do not tumble dry.
Minimal shrinkage (approx. 3–5%) — check the size chart to plan your ideal fit.
