I'm thinking about picking up a tri-suit for my first sprint tri in March. I've heard that you should by a tri-suit at least a size smaller than your regular gear. I'll probably shop online, and although I know I can always send something back I would rather get it right the first time. Is this sizing rule of thumb true? I'm 6'1, 175lbs, and dropping down to a medium in anything just sounds crazy to me.
Also, can anyone recommend a good suit that won't break the bank? Thanks!
