95% polyester and 5% polyurethane is a durable and stretchy material, perfect for everyday wear. Polyester is lightweight, quick-drying, and wrinkle-resistant. The addition of polyurethane makes it fit the body well and easy to move in. Because it's quick-drying, it's comfortable even in situations where you sweat easily. It feels smooth against the skin. It's wrinkle-resistant and easy to care for. It's sensitive to high temperatures and humidity, so it's best to avoid using a dryer.
