What Are Wetsuits Made Of?

What Are Wetsuits Made Of?
Wetsuits are worn by a variety of water sports enthusiasts: surfers, scuba divers, water skiers and snorkelers, among others. Their construction offers both buoyancy and protection from cold water.


Wetsuits are made mostly of neoprene, a synthetic rubber. Because neoprene is prone to being torn, it is not uncommon to see wetsuits made with some Lycra or wool woven into the fabric.


When the neoprene is fabricated, micro-bubbles of nitrogen are formed inside it. This makes the wetsuit buoyant and improves its insulation properties.


Although wetsuits are buoyant, they are no substitute for a life preserver and can serve as little more than a swimming aid. Their main use is in keeping the wearer warm in cold water.


Water is roughly 25 times more effective than air in stripping heat away from the body; wetsuits decrease the loss of body heat.

How It Works

Wetsuits work by trapping a thin layer of water between the neoprene and the skin. Because the water can only enter and exit through the narrow wetsuit openings, it is quickly warmed by body heat and adds to the neoprene's insulating qualities.

Fun Fact

According to the May 28, 2008 Times newspaper, Hugh Bradner (who died in 2008) was both the key pioneer in developing neoprene for wetsuits, and also an important Manhattan Project researcher on the first atomic bomb.
