Numbers indicate wetsuit thickness

The numbers indicate the thickness of the neoprene. This is in millimeters. For example, a 5/4 wetsuit has neoprene of 5 mm and 4 mm. The thick neoprene is actually always on the chest, back and waist. The thinner parts of the body are usually the legs and arms. This provides more flexibility for the body parts that move continuously and extra warmth on the chest and back.

If you only purchase one wetsuit, a 5/4 mm is recommended.

Quality difference in wetsuits

You lose body heat even faster in the water. It is not only important to choose the thickness of the wetsuit. There is a lot of difference in quality. For example, a thinner wetsuit of good quality can be better than a thick wetsuit of lesser quality. A wetsuit with seams stitched, taped on the inside and sealed on the outside has the best insulation on the seams. In addition, a wetsuit with a lining on the inside (feels like terry cloth) also provides extra warmth. A wetsuit must also fit well so that the insulation is optimal. If you want to buy the best wetsuit, you will also have to fit. Because your own construction also plays a role in determining the best wetsuit for you.

Buying a wetsuit guide

As a guide you can use a 4/3 mm or 3/2 mm in the summer and at the beginning of autumn when the water temperature is still high after the summer. For winter and spring you need at least a 5/4 mm wetsuit for kite surfing. If you only purchase one wetsuit, a 5/4 mm is recommended. This thickness can actually be used all year round in the Netherlands, with the exception of the really cold winter days with a poor wind from the north.
