OK, How about Dry Suits?

[matt t.]

The DUI CF 200 is "crushed" neoprene and is a "shell" suit which will require a thicker undergarment like any other shell suit. The Poseidon "Uni Suit" (described above, with the crazy long zipper) is a full, "thick" 7 mm suit, that has been around forever (though I've never seen one in use locally) and doesn't require a thick under garment. The DUI CF200 and the Posidon are NOT the same. I would stay away from the Poseidon suit (as well as any other thick neoprene dry suit). Let us know what you end up buying.
