Coverstitched collar

Look inside the neckline of most rib-collar tees and you'll find two parallel lines of stitching holding the band to the body — a coverstitch, laid down by a machine running two needles and a looper thread that chains along the underside. It does two jobs at once: seams the neckband to the shirt body, and flattens the seam allowance so the collar doesn't roll or curl after washing. A typical neck coverstitch runs 10 to 14 stitches per inch depending on machine and fabric weight.

Buyers checking a blank sheet will see "coverstitched neck" or "double-needle collar" listed as a durability feature, and it's a legitimate one — two rows of thread give the seam redundancy if one line gets snagged or worn. Gildan's heavier tees and most mid-tier promotional blanks use this as standard; ultra-budget import blanks sometimes use a single row that curls faster. We've had customers return shirts thinking the collar was defective when it was just a cheaper single-needle seam doing what it's built to do — lie less flat.

When choosing between blanks for a heavy neck print or embroidered collar label, a coverstitched neck gives a more stable, flatter surface than a plain overlocked seam. It comes standard on the garment, not as a spec option, but it's worth confirming on uniforms and workwear where the collar takes daily stretch.

Buyers sometimes assume coverstitching and top-stitching are the same thing. Top-stitching is any visible finishing stitch line; coverstitching specifically means this twin-needle-and-looper construction, which looks identical across dozens of garment brands but performs very differently from a single straight stitch.
