Neoprene is more designed to trap water against the skin as a warm layer - hence "Wet Suit".
Neoprene comes in different thicknesses with common thickness ranging from 6mm to 3mm with the occassional 2mm and 1mm. I have 1mm socks that I use inside my fins for Winter bodyboarding ....... the only problem being than any 'wee-wee' ends up in the socks and not in the water


I have found neoprene gloves to be nigh on useless as they are too thick and bulky to effectively handle your rod/reel or tie flies on with.
Sealskinz may be worth a look and I wouldnt like latex as I reckon your hands would sweat and wrinkle up badly.
Personally, I wont wear gloves and prefer to simply keep my hands dry and in my pockets or around a cup of coffee (with Frangelico

)
Best wishes
