Rash guards are versatile and protective athletic shirts designed for water-based activities. Made from quick-drying and lightweight materials like Lycra or polyester, they provide a comfortable, form-fitting layer to shield the skin from chafing, rashes, and the sun’s harmful UV rays. Ideal for surfing, swimming, snorkeling, and other water sports, rash guards offer both practicality and style, making them a must-have essential for any water enthusiast.
