You'd have more luck finding decent outlet stores in the US than Thailand. They're not really that sort of place, notwithstanding most of the tennis stuff is made elsewhere - not Thailand.
Sport Nova is just another standard retail outlet, I've never really seen much of interest that I couldn't find easily elsewhere. And, they're not really cheap either > the 2012 US Open Federer shorts when I was there were like 1500 bath which is US$50.. not exactly outlet prices imo.
