What is the tight-fitting material they make sportswear from. It's a body-hugging fashionable cloth?

The tight-fitting material commonly used for sportswear is called spandex, also known as Lycra or elastane. This fabric is known for its exceptional elasticity, allowing for a snug, body-hugging fit that enhances comfort and freedom of movement during athletic activities. Spandex is often blended with other materials like polyester or nylon to create moisture-wicking and breathable sportswear suitable for various sports and fitness activities.
