With the Canadian men's Olympic hockey team shutting out their first opponent, Norway, earlier this week, demand for Team Canada merchandise is going through the roof.

But some fans are having trouble finding the most coveted item: the jersey, which is sold out in many stores.

Calgary resident Denise Moumos has been on a frantic hunt for the past week at Market Mall in the city's northwest trying to find Team Canada clothing for her six-year-old son.

"I've been coming every day," Moumos said. "Last week, I came, and I found him a jersey, and now, I'm trying to find him the T-shirt, and it's impossible."

She's hunting for friends, neighbours and family, as well.

"I've got a team of people to call if I find anything," she said, laughing. "I would take sweat pants — anything."

The Team Canada jerseys feature a large maple leaf crest in the centre on either a red or white background. Inside the crest are smaller maple leaves representing past gold medal counts for Canada's men's, women's and ice sledge hockey teams and a nod to the traditional Team Canada image of a hockey player and stick.

The design also includes a thunderbird and an eagle — two powerful First Nations symbols — supporting and protecting the central maple leaf. A small Nike swoosh appears above and to the left of the maple leaf.

Along with Sidney Crosby's No. 87, there's a big demand for jerseys bearing Jarome Iginla's No. 12. The Calgary Flames captain was one of Canada's most dominant players in its first game against Norway.

It took less than an hour for all Crosby and Iginla jerseys to be sold out at Market Mall, although retailers say they are trying their best to keep up with demand.

"We've been selling a lot of them," said Joey Cuillerier at Sport Chek in Market Mall.

Store managers are expecting demand to increase even more as Team Canada takes on Switzerland later Thursday.
