Living in Texas I think you would want to stay away from the Neoprene. You will sweat alot in them. Go with a pair of breathable waders. I had numerous types over the years and had worn out so many pair that I decided you get what you pay for. I purchased a pair of Simms Gortex stocking foot waders with Korker shoes a few years ago and still have them to this day. They have an excellent warranty but cost alot more than other types. I was buying the cheaper Cabelas breatable waders and wearing them out in one season. That was unacceptable at $129.00 a pair.
