Interlock

Interlock fabric is a type of double-knit textile that interlocks knit construction resulting in a thicker, stronger, and stretchier material. It has a smooth and uniform appearance on both sides and is typically made from cotton, polyester, or a blend of fibers. Interlock fabric is easy to work with and is commonly used for activewear, including leggings, dresses, and other comfortable apparel due to its form-fitting properties.
