Breathable fabrics are materials designed to allow air and moisture to pass through them, helping to regulate temperature and keep the wearer comfortable. These fabrics are often used in clothing, especially for outdoor activities and sports, as they help wick away sweat and prevent overheating. Common examples include cotton, linen, and synthetic materials like polyester and nylon that have been engineered for breathability. The key feature of breathable fabrics is their ability to promote airflow while still providing some level of protection from the elements. This makes them ideal for activewear, athletic gear, and outdoor clothing, where comfort and moisture management are essential for performance.
