How a Wetsuit Works

Before you determine which wetsuit you need, it is useful to understand how a wetsuit actually works. A wetsuit traps a thin layer of water between your body and the wetsuit material, letting your body warm the water to a comfortable temperature. The thicker your wetsuit, the longer and warmer your body will remain in the water.

To keep your body warm and dry, many wetsuits are made with a material called neoprene. Neoprene is a synthetic, elastic rubber with excellent insulation properties. The thicker the neoprene in a wetsuit, the warmer you’ll be in the water. The neoprene in a wetsuit traps the water between the suit and the skin while body heat warms the water, reducing heat loss in cold water. Buoyant and lightweight, neoprene can also be used as a protective cover because of its resistance to abrasive textures.

Thickness and Warmth

To determine how thick of a wetsuit you should buy, you will need to take into account the temperature of the water. If you plan to use a wetsuit on the beach in the middle of summer, your wetsuit will be much thinner than if you wanted to use it in the winter. Wetsuits aim to keep warmth in and cold water out. The colder the water, the thicker your wetsuit should be. Some wetsuits use air chambers on the outside of the suit to trap heat. Fused with a locking zipper, this mechanism blocks out water to prevent flushing. Below is a chart to help you decide what style and thickness (mm) of wetsuit is right for your water climate.

Freedom of Movement

In the water, your movements shouldn’t be restricted. A wetsuit that is too snug will make it hard to swim properly. Your wetsuit should fit comfortable against your skin, without restricting arm, leg or body movements, but snug enough that water can’t easily get in. Each wetsuit manufacturer has their own standard sizing for wetsuits, which may vary between companies.


Each wetsuit has its own kind of seam, each with its own set of pluses and minuses:

  • Overlock Stitch: Found on the least expensive wetsuits, the overlock stitch sticks out of the neoprene, which can be uncomfortable. Although strong, this stitch leaves needle holes for water and wind to enter the wetsuit.
  • Flat Lock Stitch: A completely flat stitch that goes through both sides of the neoprene shell. This does NOT provide a water tight seal.
  • Glued and Blind Stitched: This stitch is first glued together then threaded with a needle on the same side, not going all the way through. Continuous stretching and use over time may create small holes.
  • Liquid tape: Rubber used to seal the inside and outside of the stitching, creating a 100% waterproof seam.
  • Neoprene Tape: Most flexible seam tape. Can be used on the inside of the seams, creating the most flexible 100% waterproof seal.


The zippers on your wetsuit can vary as well, which determines how you get in and out of the suit itself:

  • Back Zip: Opens vertically down the back, making it easy to put on and take off your wetsuit. However, this type of zipper also reduces flexibility and can be stiff.
  • Chest Zip: Zips horizontally crosses the upper chest, providing more flexibility on the back of the suit. This kind of zipper keeps water flushing through the suit while swimming or surfing.
  • Zipper Free: Wetsuit is made of neoprene with flexible liners utilizing Velcro™ closures, keeping the cold water out and flexibility in.
