The Powerskin ST 2.0 marks the next generation of arena's longest-standing FINA-approved range of racing suits. Superior knitted fabrics have been augmented in the ST 2.0 with an extra durable lining to provide outstanding stretch, optimal compression and total freedom of movement. The result is a high-performance suit that minimizes surface drag for exceptional hydrodynamics and offers unrestricted movement without compromising key muscle support. Incorporated into the top front of both the full suit and the jammer, and extending down the back of the leg, the new lining provides greater muscle compression for targeted areas, and improves core and leg support. Bolstered by the shell fabric and durable lining, the shoulder strap provides greater support in the shoulders and upper back, enhances the overall fit and feel of the suit, and adds an extra level of durability. In the ST 2.0, the seams have been moved to deliver greater ergonomic qualities, helping with body and leg lift and positioning, while also offering unrestricted biomechanical movement. In addition, flatlock construction of the seams contributes to the suit's perfect fit, with the seams sitting snugly against the body to help keep optimum shape in the water.
