Wetsuits work by trapping a thin layer of water between your body and the suit. This layer of water is warmed by your body which prevents you from losing too much heat while in the water. Water molecules conduct energy (heat) 25-40 times faster compared to air molecules.

What is the point of a wetsuit?

Wetsuits are usually worn by swimmers, divers, or surfers who swim in cold water. Wetsuits insulate the swimmers, or help them retain body heat. This, in turn, helps the swimmers avoid hypothermia, a dangerously low body temperature. Wetsuits are made of a kind of rubber called neoprene.

Do you really need a wetsuit?

First of all, if your event is going to take place in colder water, colder climates, or at higher altitude, then a wetsuit is a must, no doubt about it. Also, if the swim is over 100 yards or more, we highly recommend a wetsuit.
