Stretching a cap involves gradually increasing its size to improve its fit or accommodate a larger head. This technique is commonly used to adjust the fit of baseball caps, beanies, and other types of headwear made from stretchy materials like cotton, polyester, or spandex.
Stretching a cap can provide several benefits. It can enhance comfort by eliminating tightness and pressure, preventing headaches or discomfort during prolonged wear. Additionally, stretching a cap can extend its lifespan by reducing the risk of tearing or deforming due to an improper fit.
