John Sundnes: Ironskinn director on testing done to develop shark bite resistant swimwear

Help is on the way for swimmers afraid of shark attacks. Auckland-based Ironskinn swimwear has created a range tested to resist shark bites. The product has gone through eight rounds of bite testing by great whites, bull sharks and tiger sharks. Executive Director John Sundnes told Tim Dower the high strength materials are layered up to be around five millimetres thick. He says the shark teeth will get in but the shark will lose energy and not get through the garment. LISTEN ABOVE  See omnystudio.com/listener for privacy information.
