A sport bikini is a type of swimwear designed for active women who engage in water sports or fitness activities. It typically features a supportive top and a secure bottom, providing comfort and coverage during movement. Sport bikinis are made from durable, quick-drying materials that can withstand the rigors of activities like surfing, swimming, or beach volleyball. These bikinis often come in various styles, including racerback tops and high-waisted bottoms, to enhance performance and support. Many brands focus on functionality while also offering trendy designs, making them popular among athletes and fitness enthusiasts alike.
