"XL" typically refers to a size designation in clothing, indicating "extra large." It is used to describe garments that are larger than standard sizes, providing a more comfortable fit for individuals who require more room. The size can vary between brands, so it's important to check specific sizing charts when shopping. In addition to clothing, "XL" can also refer to various products or services that emphasize a larger or enhanced version. For example, XL Energy Drink offers a larger serving size compared to regular energy drinks, catering to consumers looking for more energy in a single serving.
