My experience exactly. We ride in a lot of hot weather and the neoprene girths were absolutely slimy and slipping part way through a trail ride. We also had to be very careful will girth rot because the neoprene did not absorb or spread the sweat. We have all switched back to mohair or wool. If you live in a warmer climate, I don't suggest neoprene.Maybe my boy is just a cow, but if we are having a serious ride and working, the cinch tends to slip because he sweats so much. No matter how much I tighten and retighten it.
