Neoprene
Most wetsuits are made from Neoprene, a specialized plastic. Various thicknesses of Neoprene are used, from 2mm to 9mm, depending on the temperature of the water the surfer will be in. The thicker the material, the warmer the suit.
Spandex
Highly useful in temperate climates, spandex is a good material choice for wetsuits. It is also used with Neoprene for extra stretch. Combination wetsuits use approximately 20-percent spandex and 80-percent Neoprene.
Nylon
Durable and protective, nylon is used to line both the inner and outer portions of some wetsuits, making the suit resistant to abrasion and scuffing. Nylon reduces flexibility in exchange for protection.
Thermoplastics
Thermoplastics, marketed as Thermoskin, are thin, heat-reflective materials that have good sealing qualities. Surfers often use a thermoplastic wetsuit underneath a traditional Neoprene wetsuit for added warmth in cooler waters.
Titanium
Using titanium threading in a Neoprene weave, or titanium oxide in the lining, increases retention and warmth in high-tech modern wetsuits, due to the reflective qualities of this metal.
