This garment uses 100% pre-shrunk cotton. Pre-shrinking cotton helps to eliminate shrinkage over time. This manufacturing process uses agitation, heat, and moisture (pre-wash) to tighten the fabric and reduce the space between threads (shrinking the cotton) prior to manufacture. This helps to improve the overall quality of the garment and means you can love it – and wear it – for years to come. Pre-shrunk cotton will generally only shrink 2-5% after the first wash.
