flatlock

Stretch fabric join

Flatlock is a sewing technique that joins fabric with a flat, stretchy seam, commonly used in athletic wear, underwear, and activewear where bulky seams would cause chafing or discomfort.

The stitch interlocks two pieces of fabric so they lie flat against the skin rather than overlapping.

These running shorts have flatlock seams for comfort.
