The PZ2TX is a streamlined swimskin built off a decade of design and testing in the non-wetsuit arena. Hydrophobic energy fabric provides an excellent fit, great coverage and exceptional speed in the water. Welded seams further reduce surface drag. Bio-mechanically engineered compressive properties drastically lower wave drag and boost performance. The locking zipper allows you to slip through the water and transition with ease.Swimskins are a thin, compressive fabric suit designed to maximize your speed when the water is too warm for a wetsuit. They do not provide buoyancy or warmth like a wetsuit.
