A rashguard is a nylon lycra shirt that can be worn in the water to protect your skin. It is designed to fit tightly so that it doesn't move around your chest in the water.
When you do water sports like bodyboarding or surfing, your skin is constantly in contact with water objects. This can cause a painful rash. A rash can even be caused by wearing a lifejacket while water skiing or snorkeling. Rashguard for females provides UV protection up to 50+.
