Scuba wetsuits are worn by scuba divers to keep themselves warm when they are in cold water.
Wetsuits trap a thin layer of water between the skin and the rubber of the wetsuit. Water will escape from between the suit and the body if the wetsuit is too loose a fit, taking the bodys heat with it.
Scuba wetsuits made of dense neoprene offer great warmth and protection. However, thanks to modern technology, wetsuits designed with a higher torso thickness are now just as flexible as wetsuits designed with lower torso thicknesses.
You just can’t afford to take any chances with poor quality ill fitting scuba wetsuits.
