Wetsuit Thickness Explained


Wetsuit Thickness Explained


Wetsuits are made of mostly neoprene come in several different thicknesses. The thickness of wetsuits differ primarily because of water temperature. Typically the thicker the wetsuit the colder the water you can be in.

What does 3/2mm Mean?

Wetsuits thicknesses are measured in millimeters. The 3 stands for 3 millimeters and the 2 stands for 2 millimeters. If for example you are looking at a 3/2mm wetsuit, the 3 stands for how thick the neoprene is in the core, (typically defined by the chest and back) of the wetsuit. The 2 stands for how thick the neoprene is in the the arms and legs. It is important to know how cold the water is that you will be practicing your activity, this will help you determine how thick your wetsuit should be. In this case, the 3/2mm is typically a wetsuit for 62-68 degrees Fahrenheit and up. As you will read below, there are flatlock stitched 3/2mm wetsuits (non-sealed seamed) and glued and blind stitched (sealed seamed) wetsuits. The sealed seam wetsuits will provide more warmth because the seams do not leak water.
