Neoprene with nylon lining on one side, usually the inside, to provide a comfortable finish and aid donning of a wetsuit. Also called mesh neoprene. Usually found on chest and back panels providing a warmer finish as the external surface improves water run-off resulting in reduced windchill.

Neoprene with nylon lining on both sides, inside and outside – for protection, durability and warmth. Multisport wetsuits are usually constructed using the majority of double lined neoprene.

Titanium added to the majority of neoprene utilised on the main body panels to enhance thermal properties of neoprene less than 5mm thickness. Most neoprene these days has a degree of titanium lining but ultimately the overall neoprene thickness, seam construction/finish and fit has the greatest influence on the overall warmth of the suit.
