There’s really no debate: we make the best swimskin in the world. The PZ4TX is our latest highly advanced swimskin legal for all non wetsuit swims. It’s combination of hydrophobic fabrics and welded seams reduce surface drag while the compressive properties improve swimming position and athlete performance. All of this while adhering to intense textile regulations. The PZ4TX builds on ten years of swimskin development and it’s why the world's best open water swimmers choose blueseventy in Kona and warmer waters.
