I cannot imagine anyone in SC needing the Fanatic suit.
Being from WI, we hunt in weather from 75 down to well below zero. My suggestion would be to layer. My basic recommendation would be the Fanatic Lite jacket and bobs with a stratus vest to start. This will probably be the same or less than the Fanatic suit and be more forgiving to weather changes.
I personally have the Core Light weight and Heavy weight tops and bottoms, Equinox pants, Fanatic hoodie, Fanatic Lite jacket and bibs. This system works for September mule deer all the way down to short sits for coyotes in January. My main hunting is probably the November rut with temps under 20 degrees with wind and it works great.
Hope this helps.
