Apnea line is a static rope designed for water sports. Freedivers, who often travel to train, compete or work, especially favour it. Apnea line is also very popular among freediving instructors. Made out of PPV and multiplex fibre, the rope has several outstanding properties. Due to its design it has minimum elongation (4%), high strength, abrasion resistance and it does not harden even after several years of usage. PPV is chemically stable, non-flammable, non-absorbing and floats. Also, it is both light and dries quickly.
