They were the Zippers until the 1950s and were named following a B.F. Goodrich brand of boot featuring a metal zipper. After taking some ribbing when zippers got more popular on clothing, it was shortened to Zips. The mascot has been a kangaroo since the early 1950s and was originally known as Mr. Zip. Today her name is Zippy and one of only eight female mascots in the country.
