ARENA Powerskin ST Next One Piece Women's Swimsuit, FINA Approved Tech Suit, Women's Recycled Fabric Swimsuit, Women's Lined One Piece Swimsuit with Reinforced Shoulder Straps Black B0CFWQT9TX

FINA/WORLD AQUATICS APPROVED: ST Next is the trailblazing FINA-approved women's tech suit that contains 60+ percent recycled fabric; its design ensures greater lightness, strength and speed during any swimming competition RECYCLED FABRIC: this women's racing swimsuit is made with fabric derived from recycled yarns; the outer shell consists of 65% polyamide, 35% elastane, while the inside lining consists of 84% polyamide, 16% elastane (eco-friendly fabric: 100% of the polyamide of the outer shell is recycled). PERFORMANCE: The modern ST Next women's arena swimsuit is significantly lighter than the previous ST 2.0 version, which results in less water absorption and drag; in addition, the increased support and compression on the abdomen and legs help for a powerful swim and a hydrodynamic posture GOOD FIT: Ergonomic design with flatlock seams ensures an optimal fit and freedom of movement; in addition, reinforced shoulder straps give it added comfort and durability EASY TO WEAR: The ST Next's state-of-the-art fabric has greater elasticity, making it easier and faster to put on and take off than other racing suits, while providing adequate targeted compression
