I live in Sarasota, FL too, and I own the NX-250. The hammock is mosquito proof, as far as I'm concerned. I've never been bitten through the material.
IIRC, there was one member here who got bit through their Clark bottom, but it was where the pocket stitching holes were sewn through the bottom fabric.
I've also camped in some very swampy areas (approx. foot deep standing water all around me), and the Clark keeps you high and dry.
Yesterday's tomorrow is tomorrow's yesterday. It's the only day that counts.
