Product Overview & Key Features
Heavy interlock fabric is a double-knit structure engineered for thickness, durability, and thermal performance. Constructed with two interlocked needle beds, this fabric offers a smooth surface on both sides, enhanced density, and superior dimensional stability compared to lighter knits. With weights typically ranging from 220 to 320 GSM, it delivers a substantial hand feel suitable for colder seasons.
The fabric combines softness with structure, making it comfortable for direct skin contact while maintaining shape in finished garments. Cotton-rich blends improve breathability and moisture absorption, while polyester content enhances strength and wear resistance. Additional finishes such as brushing or sanding can further improve warmth and tactile comfort. This makes heavy interlock a reliable choice for premium casualwear and functional apparel requiring both comfort and durability.
