Interlock Fabric questions
What is interlock fabric?
Interlock is a double-knit — two jersey faces bonded back to back. Thicker, more stable and more opaque than single jersey, with the same soft hand. We stock interlock styles by the yard, every one measured for weight, width and fiber.
What weight is interlock fabric?
Most of our interlock fabric runs 150–349 gsm. Lighter pieces suit drape and layering; heavier ones hold structure.
Is interlock fabric stretchy?
Yes — 54% of our interlock styles are stretch-rated, and spandex blends recover in all directions. Prefer stability? 88 low-stretch options are one filter away.
What is interlock fabric used for?
Polos, structured tees, kids’ clothes and dresses that need a little body.
