Flatlock Stitching

The seam that makes rash guards comfortable: flat, strong and stretchy, with no ridge to rub during a long roll.

What flatlock is

A flatlock seam joins two fabric edges side by side (butted, not overlapped) and covers the joint with interlocking stitches on both faces. The result is a seam that's nearly flat, stretches with the fabric and has no bulky inner ridge.

The standard for performance wear is 4-needle 6-thread flatlock, which gives a wide, strong, decorative seam.

Why it matters for fightwear

  • No chafing: nothing raised rubs against skin during grappling.
  • Stretch: the seam stretches as much as the fabric.
  • Durability: multiple needles spread load across the seam.
  • Looks finished: the visible stitch reads as quality on product pages.
