One-Piece vs. Two-Piece

Any thoughts on a full 5mm vs. a two-piece 3mm farmer john and long sleave shorty. Does one layer of 5 give you more or less warmth than two layers of 3? Cold is a subjective thing, so I'm interested in the mechanics of these different styles.

The full 5mm I'm looking at is the Bare 5-4 with 4mm in the joints, sleaves and lower legs. I like full suits for all conditions, so I wouldn't ever wear just the shorty portion of a two piece in the summer. I have a full 3mm for that.

In my experience a good fitting one piece 7mm wet suit, or preferably a semi dry, is as warm as a 2 piece 7mm shorty/farmer john wetsuit. My thoughts are that there is less water flow in the one piece, provided it fits well, which makes up for the decreased insultation in the torso area. I think this would apply as well to 5mm or 3mm suits.

In your case I think the overall greater insulation of the 5mm suit would make it even warmer realtive to a 3mm farmer john and shorty.
