Maybe just a bit of thermodynamics is in order.  It is my
understanding (please correct me if I'm wrong), that at least for a
submerged diver the heat loss due to conduction >> than any due to
radiation.  Radiative heat loss (or the Ti's supposed ability to
reflect heat, limiting this factor) is probably overwhelmed by
conductive losses.  The way to limit heat loss in a wet suit is to:

		1.  Limit the amount of water flushing through the
		suit

		2.  Improve the insulation of the suit, limiting the 
		conductive losses through the neoprene

Plush linings supposedly limit water flushing.  Is a Ti lining better
than a 'normal' nylon lining at this task?  Does a Ti lining add some
very effective insulating layer between the diver and the ocean?
