If you take a trip to International Drive, there is a sports store called Sports Dominator. This is excellent for american sports tops. They have everything. I buy all my tops from here.

Sports Authority is pretty good. A place called Target are good and cheap goods on sale. Even the old favourite Walmart is ok.

Also, as you are on the 192 if you visit Old Town there is a US Sports store there. That has good stuff.

Enjoy your holiday. Weather will be awesome !
