What is Interlock Fleece Fabric?
Interlock fleece fabric is a double-knit fabric brushed on the face, back, or both sides. Generally, interlock fabric has a technical face (V-shape) on both sides, which means the same appearance in front and back. However, interlock fleece is brushed to enhance its smoothness, soft surface, and insulating properties.
