How to Buy A Wetsuit

How to buy a wetsuit.

Here’s a few tips to consider before you buy a wetsuit. Wetsuits are designed for specific sports and activities. The right wetsuit will protect you against water and weather conditions, keeping you warmer, more comfortable, and safer in the water. Read on to learn how to buy a wetsuit that fits your needs.

Choosing the Proper Wetsuit

First, ask yourself: what will I be using my wetsuit for? Body Glove and other top wetsuit brands make different wetsuits for different activities. If you plan to use your wetsuit primarily for scuba diving or snorkeling, you won’t buy the same wetsuit as your surfer buddy would buy. Whether you’re water skiing, wake boarding, surfing, swimming, or hitting the waves on a personal water craft, there’s an ideal wetsuit that’s designed for your needs. This is what you should buy.

It is important to know the water temperature and weather conditions where you will be using the suit. Different wetsuits should be used based upon both geographical locations and the seasons of the year. If you are not sure what conditions to expect, call some local shops that carry wetsuits and find out what you’ll need before you buy.

There are several different kinds of materials and sewing constructions used in making wetsuits. Remember that a wetsuit is not designed to keep you completely dry. A small amount of water will enter through the seams, zipper, neck, arms, and legs. Your body temperature will heat the thin layer of water that is trapped between your body and the material. This may take 3 to 10 minutes depending on the construction, materials, water temperature, and your body’s reaction to the water.


Familiarizing yourself with the different types of seam construction is an important part of learning how to buy a wetsuit. The different types are:

1. Overlock Stitch

2. Flatstitch or Flatlock

3. GBS – Glued & Blindstitched

4. GBS with seam tape

Overlock is recommended for warm water 65 degrees F and up. The seams are stitched on the inside. From the out side you will not see any stitching. On the inside you may recognize this construction from clothing. It is commonly used on sweat shirt and T-shirt seams. Some water may seep in through these seams.

Flatstitch or flatlock is recommended for warm water too, 62 degrees F and up. You can recognize this seam from the outside; this stitch looks like railroad tracks. The interior and exterior seams look about the same. The interior seam construction is flat and is more comfortable against the body than the overlock stitch. Some water may seep in through these seams too.

Blindstitch is recommended for colder water. This construction is best for colder water because the seams are glued and then stitched, to help prevent seepage. This seam construction looks similar to the flatstitch, but is narrower. The seams are glued and bonded together, and then stitched in such a way that the thread and needle holes penetrate only the top area of the surface. Some seams are only stitched on one side. Very little water if any will seep through these seams.

Blindstitched with seam taping (Fluid Seal) is recommended for extremely cold water, usually 50 degrees F and below. The seam construction is the same as above except that the inner seams are reinforced or covered with tape. Very little water if any will seep through these seams.


Before you concern yourself with what size wetsuits will fit you best, you need to figure out what type of material (and what thickness) you need. There are many different kinds of material available, though nearly all are a variant of neoprene. Most wetsuit manufactures will use similar materials, though they may have different names for them. The materials have changed drastically over the last several years. Wetsuit materials have become more flexible, warmer, and more durable as technology continues to improve. The best materials are usually found in suits featuring blindstitch construction.


Wetsuit materials come in different thicknesses, measured in millimeters. Thickness is expressed using two numbers, separated by a slash. The first number represents the thickness of the material covering the torso, and the second represents the thickness over the arms, shoulders, and legs. Cold water requires thicker material, up to 7/6 mm. Warmer water requires less thickness, perhaps 3/2 or 2/1 mm.

How should a wetsuit fit?

Wetsuits should fit you like a second skin. You’re new wetsuit should not have any folds or loose pockets of air visible when trying it on. Don’t buy a loose wetsuit, this will not keep you warm and will more than likely fill up with water. Wetsuits will not feel overly comfortable when being worn outside of the water. When a wetsuit is wet it will become 10% stretchier and far softer. If you have any questions about what size you should buy feel free to ring our friendly staff on 0800 WETSUIT.
