Heavyweight Jersey

Heavyweight single jersey is differentiated from standard jersey by its increased yarn count and tighter stitch density, raising the fabric mass above 200 g/m² and typically into the 220–260 g/m² range for quality T-shirts. The additional mass provides full opacity — eliminating the layering and undergarment visibility concerns of lightweight jersey — and a substantial drape that falls with body rather than clinging. The tighter loop structure reduces pilling tendency and increases durability under repeated washing and wear. Premium heavyweight jersey for T-shirts is typically 100% combed ring-spun cotton, where the combing process removes short fibers to produce smoother yarns that knit up with a finer, more consistent surface finish. The weight also contributes to shape retention across the shoulder seam, preventing the "droop" common in lighter T-shirt fabrics.
