Editing Wetsuit (section)

====Wetsuit lining====
The cut surfaces are usually bonded to a synthetic knit fabric, which provides much greater tear resistance, at the expense of some loss of flexibility and stretch. This fabric can be bonded to one or both surfaces in various combinations of composition, weave, weight and colour, and can be thin and relatively smooth and fragile, thicker and stronger and less stretchy,for high wear areas, or a plush type liner to reduce water flow. Merino wool liner fabrics have also been used. Fabric lined on one side only is more flexible than double lined.<ref name="O'Three" /> After slicing the foam slab down to the required thickness, a layer of glue is applied and the chosen lining is pressed down by the lamination rollers. A more flexible lining is chosen for most applications.<ref name="Lining" >{{cite web |url=https://srface.com/pages/wetsuit-fabric?srsltid=AfmBOoqDFzIiDZEN_GBKciSDizZbxMMJI31VU7aFpL40HqxKiMNxJF2W |title=Wetsuit lining |access-date=14 October 2024 |website=srface.com }}</ref> Neoprene foam is also available with [[kevlar]] reinforced fabric facing for high cut and abrasion resistance. This is used for reinforcing high wear areas like knee pads.{{citation needed|date=January 2025}}

A wetsuit with a very smooth and somewhat delicate outer surface known as ''smoothskin'', which is the original outer surface of the foamed neoprene block from which the sheets are cut, is used for long-distance swimming, triathlon, competitive apnoea, and bluewater spearfishing. These are designed to maximize the mobility of the limbs while providing both warmth and buoyancy, but the surface is delicate and easily damaged. The slick surface also dries quickly and is least affected by wind chill when out of the water.<ref name="Lining" />

Both smoothskin and fabric lined surfaces can be printed to produce colour patterns such as camouflage designs, which may give spearfishermen and combat divers an advantage.{{cn|date=October 2021}}
