LOS ANGELES - A big-wave surfer has been killed after wiping out off the northern California coast, his sponsor, Volcom, said on Thursday.

Hawaii native Sion Milosky, 35, died on Wednesday at the famed Mavericks surf break, according to a statement on company's website, Volcom.com.

"Its with a very heavy heart that we bid farewell to Hawaiian family man and big wave surfer Sion Milosky," the statement said.

"After a wipeout and a two-wave hold down at Mavericks, Sion passed away. Words cannot begin to describe how saddened we are by this loss."

Jack Morrissey, Volcom surf team manager, said Milosky had flown to California from Hawaii on Wednesday morning to surf the swells at Mavericks and was killed sometime after 6 p.m.

"It was a big day of surf," Morrissey said.

Mavericks, south of San Francisco, is a legendary spot for surfers, known for hazardous conditions and waves sometimes topping out at over 80 feet.

Professional surfer Mark Foo was killed in a wipeout at the break in 1994.

A spokeswoman for the San Mateo County Coroner confirmed Milosky's body had been brought in on Wednesday evening.

She said an autopsy would be conducted in coming days to determine the cause of death.

Milosky, the father of two young girls, was recently named North Shore Underground Surfer of the Year.

Volcom said it was setting up a foundation for Sion's daughters, with information posted on the company's website, Volcom.com.

"Sion's first passion was his wife and kids and surfing giant waves was his second. Never before had we seen such an amazing surge of coverage from any surfer in a period of less than two years," the company said in on the website.

"If Sion set out to do something he would do it, no questions asked. His spirit of Aloha was unmatched and whenever you were around him you couldn't help but feel good in his presence."
