The jt3 "32-Singles" 4.3 oz Men's Tailored Long Sleeve

Silky Athletic Silhouette. Fine-Gauge Micro-Knit Canvas.

An elevated, active street rotation requires versatile, high-spec foundational layers. The jt3 "32-Singles" Long Sleeve is engineered from an ultra-soft 4.3 oz. combed ring-spun cotton jersey, knit using fine 32-singles thread for an exceptionally smooth exterior face. Moving far beyond stiff, boxy thermal layers, this piece is fabric-laundered during production for maximum softness and pre-shrunk dimensional stability. Tailored with a clean set-in 1x1 baby rib collar and streamlined sleeve drops, it provides a sculpted, weightless drape built for seamless layering under technical outerwear or vests.

• 4.3oz Micro-Knit Jersey: Crafted from 100% combed ring-spun cotton (149.2 g/m²)—engineered for maximum breathability, zero-bulk layering, and an ultra-soft hand-feel against the skin.
• Fine-Gauge 32-Singles Yarn: Woven with micro-fine 32-singles threads to create a tightly knit, high-density surface profile that resists friction, holds its shape, and feels remarkably smooth.
• Fabric-Laundered Precision: Specially washed and laundered during manufacturing to eliminate harsh fabric stiffness and lock in shrink resistance, guaranteeing the pristine fit on day one remains exact wash after wash.
• 1x1 Baby Rib Collar Architecture: Trimmed with a low-profile, fine 1x1 baby rib collar that sits completely flat against the neck, framing the collarbone cleanly without stretching or warping.
• Tailored Athletic Geometry: Precision-patterned with set-in sleeves and a contoured torso drop that hugs the chest and shoulders while eliminating excess side-bulk.

• For a Sleek, Tailored Athletic Fit: Order your regular standard size.
• For a Relaxed, Traditional Street Fit: Because of the tailored construction, we recommend sizing up one full size (or if you sit between sizes) to achieve a looser hang across the torso and arms.
