Over ten years of flume testing and design in high performance swimming product development combined with the most recent developments in textile research have gone into the PZ4TX.The result is a combination of four different hydrophobic fabrics hand-chosen for their compression and stretch characteristics. These high quality Italian fabrics are sourced from renowned textile manufacturer Taiana and were developed for our competition pool suits with hydrophobic qualities built into the yarns. These fabrics are infused to repel water instead of after-market coatings that can lose their water repellency over time.The PZ4TX swimskin ensures compressive properties with an innovative side panel that improves swimming position and athlete performance.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.
