Suana Suits?

Options
Ok, so this weekend I purchased a sauna suit. Not sure why, never found the need before, but I got curious so I just got it. I work it (boy did I look stupid) during a combat class and the next day during a weight lifting class. wow did I sweat, but Im not sure it will do anything more than that for me. It just seems like I wrapped myself in poly and sweat like a pig. I don't think it will help with any sort of weight loss because as soon as I drink water whatever I sweat out is back. but none the less I did sweat out my cruise alachol I just got off of Saturday.

anyone else use one?
