The best, and coolest, and most stingproff suit I've see is from Golden Bee products but they were on the outskirts of New Orleans and no one has heard from them since the storm, that I know of. It's three layers of mesh. The coolest and least sting proof that I have is a "bug baffler". They have a jacket with a zip on viel, pants or a seperate stand alone veil.http://www.bugbaffler.com/
It is NOT sting proof, I have been stung through it many times, but on a hot day wearing shorts and no shirt (which may not be a choice for you) it's quite the breaziest suit. Even a bit more breazy than the Golden Bee Products suit.
