I have a TT coming up in a few weeks that's going to be pretty hot. I can wear my regular lycra skinsuit, or I recently got one of these:

It's a skinsuit with mesh panels in place of lycra to stay cooler. I've worn it a couple times and it does in fact seem cooler than a lycra suit. Does anyone have any information as to the aerodynamics of this material as compared with lycra? Am I going to be taking a hit aerodynamically if I wear this thing?

I'm already heat acclimatized, and I know all the tricks for staying as cool as possible. My question is really just about the drag properties of the fabric.
