My problem with dry suits is overheating. As soon as I put one on my temp. skyrockets so I’ve decided to look for an alternative. I’m thinking semi dry top with a farmer john. Any advice as to which semi dry top to get is appreciated.
Are you trying Gore-Tex or comparable breathable fabrics?
My experience has been I get overheated much sooner, and to a much greater degree, with a wetsuit/drytop combo than with a good quality drysuit. But either way, there is always roto cooling to keep the body temp at a comfortable level.

Trim or stretch the neck gasket.
You are probably not used to the tight neck gasket and are perceiving the sensation as a rise in body temperature.
Maybe the neck gasket is too tight.
