"Matthew Bryce was reported missing by his family after failing to return from a surfing trip off the Argyll coast in western Scotland."
"Following a large-scale air and sea search, the 22-year-old was eventually found 13 miles offshore by a rescue helicopter at around 7.30pm on Monday."
"Mr Bryce was wearing a full wetsuit, which has been credited with saving his life, and had managed to stay with his board to keep him out of the water."

Anybody knows what wetsuit specifically? I'm immediately thinking spearfisher cut, long johns and jacket.
