The helmets were all made available for bids online and fetched a grand total of $2,850 ($2,300/€2,600) for the Creative Impact Health Foundation.

They were put up for sale last month and the bidding process came to a close on October 11.

It comes as part of a nationwide campaign to help prevent serious head injuries.

Seven members of Canada’s luge team, including two-time world bronze medallist Alex Gough, launched the "Put A Lid On It" initiative during the 2015-16 winter season in conjunction with the Helmets for Heroes charity.

The helmet belonging to Arianne Jones, who competed at the Sochi 2014 Winter Olympic Games, fetched $950 (£777/€862) alone.

Also taking part were Kim McRae, John Fennell, Mitchel Malyk and the doubles pairing of Tristan Walker and Justin Snith, who along with Gough and Samuel Edney finished fourth in the team relay event at Sochi 2014.

All members teamed up with children who have overcome serious head and brain injuries to design helmets with the help of local artists.

The project resulted in seven different helmets, all of which carry a message and are unique to the athlete, designer and artist.

All members of the national team wore the headgear at every round of the Luge World Cup and during the International Luge Federation (FIL) World Championships.

Last month, Fennell confirmed his intention to switch allegiances to the United States.

The 21-year-old slider competed at Sochi 2014 for Canada, but was born in Denver in the US.

Representing his country of birth for the first time earlier this month, Fennell came second in the men's event at USA Luge's annual indoor start championships.
