Boys' High-Cotton Soft Thin Korean Letter Sweatshirt

Crafted with high-density flat-seam construction (12–14 stitches per 3cm) originating from Guangzhou, this boys' Korean-style long-sleeve sweatshirt (Item No. 588-4 Thin) combines clean, western-style casual aesthetics with everyday athletic functionality. Tailored for growing boys aged 3 to 10+ years (covering a complete height metric from 90cm to 160cm), it features a light non-hooded pullover crewneck silhouette, subtle letter print accenting, a soft cotton inner lining, and neatly finished seam construction with all obvious thread ends trimmed.

Engineered specifically for mild spring and autumn conditions, the lightweight high-cotton blend (65% cotton main fabric content) undergoes specialized softening treatment to deliver optimal skin-friendly breathability, soft tactile comfort, and flexible movement for active wear. Certified under Class B safety standards for direct skin contact compliance, this versatile loose-fit top retains its structural shape, collar elasticity, and color depth through routine laundering and active school play.

Sourced as a ready-stock listing ready for rapid cataloging and multi-channel e-commerce distribution, this lightweight pullover serves as an essential, all-match base layer shirt for boys. It is offered in five classic colorways—White, Black, Navy Blue, Brick Red, and Gray—across an expansive height-matched sizing scale: 90cm, 100cm, 110cm, 120cm, 130cm, 140cm, 150cm, and 160cm.
