A sunsuit is a lightweight one-piece garment designed for sun protection and beachwear. Made from breathable materials like nylon or cotton, it covers the torso, arms, and upper legs, providing coverage from harmful UV rays. Sunsuits often feature quick-drying and moisture-wicking properties for comfort in hot and humid conditions. They come in various styles, including solid colors, prints, and designs, catering to personal preferences and fashion trends.
