Hypothermia/ neoprene waders?

When it's warm enough to use non-neoprene waders I wet wade
more often than not. The non-neoprenes I do have (and occasionally
wear)
are Patagonia waders, which I do like. But for me they are the frills.
Neoprene is the requirement.

Neoprene is warmer and it does keep you warm even when
wet. I wouldn't feel safe wading in April and November with anything
else.
