Cotton-spandex blend fabric is a stretchy, comfortable textile that combines the natural softness and breathability of cotton with the elasticity and shape-retention of spandex (also known as elastane or Lycra). Typically containing 2–10% spandex, this blend offers a flexible, form-fitting quality while maintaining a soft, natural feel.
Cotton provides moisture absorption, comfort, and breathability, while spandex adds stretch, resilience, and the ability to retain shape after wear. The result is a durable, smooth fabric that moves with the body without sagging or losing form.
