Ten years of flume testing, research and development went into the PZ4TX. The result is the absolute best swimskin for your next non-wetsuit swim. The combination of four different hydrophobic fabrics hand chosen for their compression and stretch characteristics are brought together by ultra-sonic bonded seams that reduce surface drag. The same Italian textile fabrics used in our competition swimwear ensures compressive properties that improve swimming position and athlete performance.
USA Triathlon specifies a water temperature of 78°F as the cutoff for wearing a wetsuit.
