Benefits of Wearing a Triathlon Wetsuit

A wetsuit offers more than just insulation from the cold water; it can make a measurable difference in your performance in the water by providing:

• Increased Hydrodynamics – Keeps your torso and lower body high in the water, reducing drag.
• Improved Body Position – Helps you swim more hydrodynamically by putting your body in a straighter, more horizontal line in the water.
• Energy Efficiency – Reduces effort required to stay afloat, conserving energy for the bike and run.
• Insulation – Protects against cold water.
• Confidence Boost – Provides added security, particularly for new triathletes.

How a Wetsuit Helps in Long-Distance Races

For Ironman and other long-distance races, a wetsuit can provide:

• Reduced Fatigue – Conserving energy in a 2.4-mile swim is crucial.
• Better Performance – Staying horizontal in the water (not letting your legs sink) reduces excess drag and enhances speed.
• Extra Warmth – Especially important for open-water races.

The Difference Between Triathlon Wetsuits and Surf Wetsuits

While surf wetsuits and triathlon wetsuits may look similar, they are designed for different purposes:

• Surf wetsuits are thicker, heavier, and less flexible. They are designed to provide insulation rather than help you go fast.
• Triathlon wetsuits are made with speed in mind, as well as for flexibility and quick removal during T1.

How to Choose the Best Wetsuit For You

When shopping for and trying on a wetsuit, consider:

Fit – Should feel like a second skin but not restrict breathing.

Buoyancy – Look for 5mm neoprene in the torso and hips/legs for extra floatation.

Flexibility – More shoulder and upper body flexibility means less fatigue.

Neoprene Thickness – Strategically placed neoprene allows custom floatation in key areas: Thicker panels provide enhanced floatation and durability, while thinner panels allow for movement.

Full-Sleeve vs. Sleeveless: Which One is Best?

Full-sleeve options offer better floatation, warmth, and hydrodynamics.

Sleeveless suit options provide more freedom but less flotation and warmth.

How to Find the Right Wetsuit for You

If you're shopping for a suit for your first tri, here are some of our top tips for finding the perfect suit (and the perfect fit):

1. Test different sizes—Sizes can vary across brands; it's worth trying on a few different brands and sizes to find what works best for your height, weight, and overall body type.
2. Try it on dry, then wet – A wetsuit will feel tighter dry, and looser wet.
3. Check shoulder flexibility. You shouldn’t feel restricted; practice some basic swimming movements and make sure your shoulders can move freely.

What Will I Spend?

Wetsuits are relatively inexpensive compared to other pieces of gear. An entry-level suit like the ROKA Maverick or XTERRA Vortex costs between $400 and $500. Higher-end wetsuits can cost upwards of $1,000 and boast increased hydrodynamics, different thicknesses of neoprene in strategic areas, and additional features.

We recommend purchasing a wetsuit and not renting one; wetsuits can be used several times and tend to hold their value well. So, for your first triathlon, reward yourself for all your training and invest in this essential piece of gear.

How to Wear a Wetsuit Properly for Comfort and Speed

Wearing and swimming in a wetsuit takes some getting used to. The first time you put one on, you’ll notice that you’ll work up a sweat! You may feel restriction around the neck and shoulders and feel a bit “squeezed.” With practice putting it on and using it on a daily basis, however, it will start to feel like a second skin.

Follow these steps to get the most out of your wetsuit:

1. Wear your tri suit under your wetsuit. This saves time during transitions (no need to change clothes), provides extra moisture-wicking and comfort, and works seamlessly with the neoprene layer for streamlined performance.
2. Use lubricant: Before you put the suit on, apply a triathlon-approved lubricant such as Body Glide to areas prone to chafing. Wetsuits are often the culprits for post-race chafing burns around areas such as the neckline and underarms.
3. Roll it on gradually: Start with your legs and work up to your shoulders, rolling it on from the inside rather than gripping the outside, where your fingernails can cause damage. Pull it up higher than you think you need to (even pulling the wrist cuffs a little higher than you'd normally wear) to ensure that there's plenty of space around your shoulders.
4. Eliminate gaps: Ensure the suit fits snugly, especially around the chest and arms. Pull it up higher than you think it needs to go, especially around the shoulders, and then do up the rear zipper.
5. Practice using it in training: Get comfortable moving your arms during training. Wear your suit as often as you can—even in a cold pool—so that you’re very comfortable in it come race day.

How to Care for Your Wetsuit

Your investment in a wetsuit will serve you for many, many years of training and racing. Take care of it by following these simple steps and your wetsuit will give you years of life:

1. Clean and dry your wetsuit properly
2. Rinse with fresh water after each use.
3. Hang dry inside-out away from direct sunlight.
4. Store flat or folded at the torso, not on hangers.
5. Avoid heat exposure to prevent neoprene breakdown.
6. Repair minor damage or nicks using wetsuit cement for small tears and patch kits for larger rips.

FAQ: Common Questions About Triathlon Wetsuits

Q: Do I need a triathlon-specific wetsuit?

A: Yes, triathlon wetsuits are buoyant, flexible, and hydrodynamic, unlike surf wetsuits.

Q: How tight should a wetsuit fit?

A: Make sure your suit is snug, but not restrictive. There should be no room for excess water pockets.

Q: Do wetsuits help reduce fatigue?

A: Yes! They keep you high in the water, reducing effort and fatigue.

Q: How do I know if I need a wetsuit for my triathlon?

A: If the water is cold or you’re a beginner, a wetsuit is highly recommended for added buoyancy, warmth, and safety. Wetsuits are generally recommended for temperatures below 24.6 degrees Celsius as they protect against the cold while allowing you to perform optimally.

Q: How does the temperature of the water on race day affect wetsuit choice?

A: Choose thicker neoprene for colder water and thinner or ****non-sleeved ****wetsuits for warmer conditions. Wetsuits are prohibited above 24.6°C (76.1°F).

Q: What are the benefits of wetsuits for open-water swimming?

A: Wetsuits provide several advantages for swimmers in triathlons. They help maintain body warmth by creating a layer of water that your body heats up, effectively insulating you against colder temperatures. Additionally, a specific wetsuit can provide buoyancy, helping you to float better and swim faster, which could lead to a personal best time. Moreover, they offer some protection from potential hazards in the water, such as sharp objects or marine life.

Q: What are the temperature limits for wetsuit use in triathlons?

A: According to organizations like British Triathlon, wetsuits are generally recommended for water temperatures below 24.6 degrees Celsius. If the temperature drops to 14 degrees Celsius or lower, a wetsuit becomes increasingly important for safety and performance. However, if the temperature exceeds these limits, competitors may wear a wetsuit, but it could affect their overall standing in the race.

Q: Can you still swim without a wetsuit in open water?

A: Yes, but it’s essential to consider the water temperature and your comfort level. If the water is warm enough, you might find swimming without a wetsuit more comfortable, allowing for greater flexibility and freedom of movement. However, if the water is cold, you’ll struggle without the thermal protection a wetsuit provides.
