The jt3 "20-Singles" 6.5 oz Men's Heavyweight Core Tee

Architectural Frame. High-Density Yarn Substance.

The strength of an elite street layout relies entirely on structural density, clean collar geometry, and uncompromising material weight. The jt3 "20-Singles" Heavyweight Tee is engineered from a substantial 6.5 oz. (220 g/m²) combed ring-spun cotton matrix, woven with heavy-gauge 20-singles yarn for a dense, ultra-smooth face. Moving far beyond flimsy department-store shirts that sag or cling, this piece features a masterclass side-seamed construction and a thick 7/8″ single-needle edge-stitched collar, delivering an immaculate, architectural drape that holds its shape through heavy daily rotation.

• 6.5oz Heavyweight Canvas: Crafted from high-density 220 g/m² combed ring-spun cotton—engineered to drop a bold, rigid silhouette that holds its box structure away from the body without collapsing.
• Heavy-Gauge 20-Singles Yarn: Knit with thick 20-singles threads to create an exceptionally dense, smooth exterior face profile that delivers long-term durability and superior shape retention.
• Side-Seamed Architectural Drape: Meticulously tailored with premium side-seams to follow the body's natural geometry, entirely preventing the shirt from twisting, wrapping, or losing its shape after machine washing.
• 7/8″ Reinforced Collar: Finished with a substantial 1x1 ribbed collar anchored by tight single-needle 7/8″ edge stitching, designed to sit completely flat against the collarbone and permanently eliminate neck sagging.
• Combed Ring-Spun Purity: Combed to strip away loose fibers and impurities, resulting in a plush, high-grade hand-feel that feels substantial and comfortable against the skin.

Find Your Perfect Fit

Structured Regular Block. Architectural Hang.

This tee is patterned with a classic regular streetwear block. Because of its heavy-density 6.5 oz. cotton weight, it drops straight down the torso with zero side-cling or bunching.

• For a Clean, Structured Street Fit: Order your regular standard size.
• For an Exaggerated, Oversized Street Slouch: Size up one full size to achieve a broader, boxier streetwear hang over cargos or stacked denim.
