New fitness shirt idea. Sweaty Shirts. Thoughts?

I came up with an idea for a really cool shirt design. It’s based on the concept of fitness, fun, and fashion. Basically it assumes most consumers are somewhat lazy, but also want to project the appearance that they are in good shape and just got back from working out.

Essentially they are sport shirts, but have the built in appearance of a sweat ring. Think of a light grey LSU (pending license) shirt with a dark grey ring around the collar. The initial launch will have various degrees of workout level to choose from. There’s the warmup (small, natural looking V shaped sweat ring), 1 mile (slightly larger ring), 5k (ring nearly down to the chest, beginning to show on the back), 10k (ring just below chest level), and marathon (dark ring covering most of the shirt).

They would be fun to wear in an air conditioned environment, like a shopping mall, where nobody would be sweating. Also fun to wear to the gym or football game.

What are your thoughts on the initial launch lineup?
