Fitting your wetsuit It is vitally important to get a close fitting wetsuit. Once you have an optimally fitted wetsuit on it feels like a second skin which is what makes it so effective when you are in the water. But with a garment that fits so tightly, the challenge is in how to get it on without damaging the suit or chafing or trapping your skin. Adjusting the suit to fit your body comfortably so that it doesn't cause discomfort whilst you are swimming also needs a little practice.
