looking for easy to put on winter wetsuit

I have a 6mm with integrated hood that I enter through the neck, great for winter here in New England where water temps get below 40F in March.
But putting it on and taking it off in the back seat of my car is a pain. Other than February/March, I think I could get away with a 4/3 and a vest with a hood. I need a 4/3 or 5mm that has some sort of zipper that splits it up like my 3/2, so I can put it on easier and quicker.
Any recommendations?
