The new Nero Stitch range from Blueseventy is designed to meet the updated FINA regulations for the 12 and underage group that prohibits woven and bonded or taped suits. The Nero Stitch Jammer goes even further, promising a suit that provides both comfort and performance.� This ergonomically designed suit offers targeted compression in order to improve your body position and decrease resistance, resulting in more speed. Hydrophobic knit fabrics mean a comfortable fit, while the flat lock stitched seams maintain the suit's flexibility, speed, and comfort.� Silicone leg grippers help keep the suit in place.
