Turn the wetsuit inside out and lay it in front of you so the fish is on top. Use a freezer bag to help you get into the wetsuit, alternatively you can wear socks. The most important rule is that the wetsuit is only ever pulled up from the inside, as there is too great a risk of a cut in the outer material. If possible, make sure that the suit is pulled up as high as possible into the crotch. The same applies to the underarm area, as the suit must fit as tightly as possible in these areas. Once you have zipped up your wetsuit and are ready to swim, you need to "flood" your wetsuit. Flooding in this context means that you let water run into the suit through the neck opening and out again at the leg ends. This is because the thin layer of water that remains between your skin and the wetsuit after flooding warms you up during your workout.
