Iceland kit-makers can't keep up with demand for the country's bright blue playing shirt, which is almost 2,000 percent higher than anticipated and has seen a spike in orders -- unexpectedly -- from Scotland, according to reports.

Iceland, who have a population of just 330,000, have made it to the last eight in their first major tournament and face host country France on Sunday in the quarterfinals.

Iceland shirt-makers Errea told the Daily Record that they are working to meet demand for the shirt from all over Europe, including "thousands and thousands" of orders from Scotland.

Rosa Sembronio, head of marketing at the Italian company based near Parma, said: "Since the win we have had many orders from all over the world for the Iceland kit. But by far the greatest surge of orders has come from Scotland, Glasgow and Edinburgh in particular.

"We are determined to satisfy all the requests and we now have our staff working day and night to satisfy demand."

Iceland team press officer Omar Smarason said on Friday that internet orders for replica shirts have overloaded Ehf, Iceland's official jersey distributor, and Errea, the Italian manufacturers.

"Based on the number of emails and Facebook messages we've been getting, yes, we are sold out," Smarason told Agence France-Presse.

"Demand is 1800 percent over what was predicted, which is good on one hand, but bad for everyone who has not got the shirt they wanted yet.

"We have every faith in Errea and we're sure everyone will get their shirt eventually."

Edrea export manager Fabrizio Taddei told The Times: "We are having huge demand and since Iceland beat England it has gone crazy.

"There have been thousands and thousands of orders from Scotland ... but there is demand from all over Europe."

Scotland failed to qualify for the tournament. Scotland fans made news for wearing plastic bags from the Iceland frozen food chain as shirts to support Iceland in their victory against England.

Puma, who make Leicester's shirts, ran out of replica kits in January, four months before the end of the Premier League season.
