ROME: The hi-tech swimsuits that have led to a deluge of world records will be banned from next year when the sport will revert to costumes made from textiles, swimming's governing body FINA said on Tuesday.

"The material can only be textile fabric," FINA executive director Cornel Marculescu told a news conference.

"The shape (of the costume) - for men shall not extend above the naval or below the knee. For women it shall not extend above the neck, beyond the shoulders or below the knee."
