There are a lot of outlet stores on Elston Ave. This is one of the many no-nonsense shops. There are many more outlet stores by Fullerton/Elston as well, but they actually start as far north as Lawrence Ave.
This store offers t-shirts, hats, socks, sweatshirts, sweatpants and other clothing that's considered sportswear or casualwear. The more quanity you buy the better deal you will get here of course. Very reasonable prices overall.
