Any chunky or bulky weight yarn, Category 5 on the Yarn Standards table. You would be looking for something labeled with a gauge of 12-15 st/4in on size 5.5-8mm/US11.
If you shop internet, at most stores you can choose to look at yarns by weight, so that may give you some ideas of brand names if you look through the bulky/chunky section.
