Because of his formal education, Hašek stands out among Czech sportsmen. He earned a university degree after studying history and the Czech language in the Faculty of Education at the University of Hradec Králové, which qualified him to be a teacher, and led him to teach high school classes. Hašek also had a brand of sportswear named "Dominator Clothing", which was launched shortly after the Nagano Olympics in 1998. It also had two locations in Michigan for a short time. However, sales were low, and the Dominator brand was forced out of business in 2008.
