How to Select the Right Wetsuit for Your Sport

How to Select a Wetsuit

Intro to Selecting a Wetsuit

When your wetsuit acts as your 壮econd skin, it’s important to do thorough research before investing in this considerable purchase. But how do you choose the right wetsuit? There are a lot of important factors to consider, such as whether you need a wetsuit primarily for swimming, surfing, diving, or multiple sports. While some wetsuits can cross-over into other activities, we recommend investing in a wetsuit that is specific to your main sport. Our guide below is designed to help you overcome any decision-making anxiety, so you can quickly determine your needs and identify your ideal wetsuit.

How do wetsuits work?

A wetsuit is made of neoprene to provide you warmth and protection when doing your favorite water sports. Wetsuits slow down heat loss by trapping a thin layer of water between your body and the wetsuit. While you still get wet, your body heats up the thin layer of water trapped against the body to nearly body temperature. A wetsuit should fit properly. The thicker the neoprene is in the suit, the warmer the wetsuit will be. Research the water temperature in the region where you will primarily use your wetsuit. If temperatures are cold consider wearing neoprene boots, gloves and hoods.

Need A Wetsuit For Swimming?

If you plan on swimming a lot or doing laps in your wetsuit, we recommend a Triathlon wetsuit. Triathlon wetsuits are specifically designed for swimmers, with more stretch than a typical surfing or diving wetsuit so you benefit from unrestricted movement while swimming. The extra stretch is due to a different cut, materials, and design than conventional wetsuits.

How Does A Triathlon Wetsuit Work?

Triathlon wetsuits have panels with different thickness and materials (buoyancy) to optimize the swimmer痴 positioning. (Note: These wetsuits are not personal flotation devices nor are they intended to protect against sinking or drowning). Additionally, triathlon wetsuits rarely have nylon lament on the exterior so they glide more efficiently in the water with less drag. While these features make a triathlon wetsuit very stretchy, they also make it very sensitive to tearing.

Need A Wetsuit For Surfing?

You may not realize it, but surfing involves a lot of arm paddling. Consider a wetsuit that has stretchier materials in the upper body (shoulders, arms) or in the entire body of the wetsuit. This will reduce the upper body fatigue that results from repetitive motion. (Insert wetsuit diagram here) In this wetsuit example, there are stretch materials in the upper body of the wetsuit to improve your surfing comfort.

Need A Wetsuit For Diving?

The two most important things to consider when determining the best diving wetsuit are: a) Water temperature – If you are diving in colder waters, consider a cold water diving wetsuit. These wetsuits are specifically designed to withstand the compression that results from going deep underwater. They are also typically made of materials that help to maximize your body痴 thermal protection. b) Water depth – you may be surprised to learn that the enemy of all wetsuits is depth, not water temperature. As you descend, your neoprene wetsuit compresses very quickly - in some cases to half of its surface thickness within the first 35 feet. So to protect your body and your gear, consider the diving depths you anticipate undertaking before determining the best cold water wetsuit for your needs.

How Does A Cold Water Diving Wetsuit Work?

When you descend down, you experience both water and air pressure. Since water is much denser than air, the pressure increases rapidly as you descend further. With deeper diving come greater wetsuit compression. This compression is actually the bubbles within your neoprene wetsuit -- which act as your insulation -- compressing due to the pressure. So as the wetsuit compresses, it loses thermal protection. While some wetsuits compress more than others in deeper water, the differences are not huge. As you might expect, stiffer, heavier neoprene wetsuits generally compress less than soft stretchy ones.


At a depth of 34 feet in fresh water, the diver experiences 2 atmospheres of pressure (1 from air pressure, 1 from the 34 feet of water). For every additional 34 feet that the diver descends, he is under an additional atmosphere of pressure. As you can imagine, this is a lot of pressure on a wetsuit!
At a depth of 90 feet, your 7mm cold-water wetsuit can get very thin depending on the type of neoprene within your diving wetsuit.

Can You Use A Triathlon Wetsuits To Do Multiple Sports?

While a triathlon wetsuit would seem like the perfect wetsuit for multiple sports it, we would strongly recommend against it. For example, if you wore a triathlon wetsuit to go scuba diving, the shoulder straps on your BCD (buoyancy compensator) would likely tear the wetsuit痴 neoprene. Other basic actions such as rubbing against coral or the back of a boat as you board, or even kneeling on the ground, would potentially tear a triathlon wetsuit. Due to these high-rip risk factors, we recommend using your triathlon wetsuit for swimming activities only.

When Looking For A Multi-Sport Wetsuit Here Are Some Factors To Consider: 1. What activity will you be spending most of your time doing in the wetsuit? 2. What is your budget? 3. What will be the most active areas of the wetsuit?


Choosing a wetsuit is easy once you determine your primary sporting use: - Do you need a swimming wetsuit? A triathlon wetsuit will give you maximum flexibility with minimal drag. - For surfing, go with a surfing wetsuit that has extra stretch in the upper body – it will greatly improve your comfort. - Are you a diver? A diving wetsuit is your best bet – but the final choice is further impacted by the type of diving that you anticipate doing: cold water or deep dive. - For multiple sport we do not recommend a triathlon wetsuit (even though it seems contradictory)
