From the product page:
Vikwool is located in the southern coast of Iceland, south of one of the country’s largest glaciers. Under the ice mass sleeps one of the most active volcano’s of the island, Katla, which wakes up once in a century.
Apparently, this blanket is a reproduction of Vikwool—although, by the looks of things, it looks well suited to covering and transporting a guy that has been recently whacked.
