Getting the right wetsuit fit is crucial for triathletes. A suit that fits well improves your speed, flexibility, and transitions in the water. One that doesn’t fit properly can ruin your performance. So how do you find the perfect wetsuit for you? 

This guide explains everything you need to know. It covers how a wetsuit should fit, key factors in choosing a size, tips for test-driving suits, and mistakes to avoid. With the right fit, your wetsuit will feel like a second skin – you’ll swim faster, warmer, and more freely. Let’s Begin!

Why Wetsuit Fit Matters

A properly fitted wetsuit is absolutely critical for triathletes. However, finding the right fit can be tricky, given all the factors involved. 

In this section, we’ll break down why the ideal wetsuit size and fit are so important for your performance, safety, and comfort in the swim. So let’s dive in and cover why wetsuit fit matters.

1. Optimal Buoyancy

A properly fitted wetsuit is critical for triathletes, as it provides three key benefits. First, it maximizes buoyancy and reduces drag. When the wetsuit fits loosely, it feels like you are dragging a parachute through the water. 

This creates significant resistance and slows you down considerably. On the flip side, an overly tight suit restricts arm and leg movements, also hampering speed and efficiency. But a suit with just the right snug fit allows you to glide smoothly through the water without compromise.

2. Hypothermia Protection

Second, a close-fitting wetsuit protects against hypothermia. The tight seals prevent cold water from flushing in and out of air pockets within the suit. This maintains your core body temperature and staves off the dangers of hypothermia during lengthy open-water swims in frigid conditions.

3. Faster Transitions

Finally, proper fit enables fast transitions. Wrestling to peel off a wetsuit that is either too baggy or too constricting can cost you precious seconds during the transition between the swim and bike legs. But a suit that fits like a glove is easy to quickly rip off, so you can dash to the next stage of the race unimpeded.

So, in essence, the right wetsuit size is not just about comfort; it’s about performance, safety, and shaving off those precious seconds from your race time.

Key Factors for Finding Your Ideal Wetsuit Size

Some are holding measuring tapes around their arms and waist, while others are examining the neoprene material of different wetsuits. Thermometers and water temperature charts can be seen in the background. A few athletes are seen checking the thickness of the wetsuits, while another points at a map showing various race locations and their respective water temperatures.

Now that we’ve established the importance of a properly fitted wetsuit, let’s explore the key factors you should take into account when selecting the optimal size for your needs:

1. Consider Your Body Type

One of the most important considerations is your specific body type and proportions. It’s essential to take accurate measurements of areas like your chest, waist, hips, arm length, shoulder width, and other vital dimensions. 

Wetsuit brands design their suits to fit a wide range of body shapes and sizes, so take the time to analyze your own proportions. This will help you identify the brands and suit cuts likely to best compliment your unique physique.

2. Analyze the Wetsuit Material

The thickness, stretchiness, and overall flexibility of the neoprene used in the suit’s construction also greatly impact fit. Thicker neoprene provides more insulation and buoyancy but can also be overly restrictive, especially for muscular builds. 

Thinner, super-stretchy neoprene offers great flexibility of movement but less warmth for cold water swims. Make sure to balance your flexibility needs with the desired insulation when selecting suitable materials.

3. Consider the Water Temperature

Another key factor is the temperature of the open water you’ll be swimming in. If you’ll be braving extremely cold conditions, you’ll want to opt for a wetsuit with thicker, well-insulated neoprene to retain body heat. But for triathlons in warmer climates, you can get away with a thinner, more stretchable suit that maximizes flexibility of movement.

4. Factor in Race Length

Also, think about the total distance you’ll be racing. For short sprint triathlons, you may only need a basic, affordable wetsuit that gets the job done. But for ultra long-distance Ironman races in frigid locales, you’ll want to invest in a higher-end thermal wetsuit specially engineered to keep your body warm and buoyant over longer durations.

By carefully analyzing these key factors, you’ll be equipped to select a wetsuit size that checks all the boxes for your individual triathlon needs. 

Tips for Trying on Wetsuits

You’re ready to start trying on wetsuits to find your ideal size and fit – awesome! But before you begin, keep these tried and true tips in mind to get the most out of the wetsuit fitting process:

1. Ensure Your Skin is Completely Dry

This is absolutely crucial. Any dampness or moisture on your skin will make wetsuits exponentially more difficult to slide into and pull up your body. The neoprene will stick and cling to wet skin. Save yourself the struggle by only trying suits on when your body is 100% dry.

2. Use Plastic Bags on Hands and Feet

For very snug-fitting wetsuits, cover your hands and feet with plastic bags before putting them into the suit. This reduces friction against the neoprene, allowing you to pull the suit onto your body with less resistance. You’ll get a more accurate feel for the true fit this way.

3. Analyze Neck, Wrist and Ankle Seals

Pay close attention to how the seals around the neck, wrists, and ankles fit. There should be no pinching, rubbing, or restriction of circulation in these areas. The seals should lay smoothly and snugly against your skin.

4. Move Around to Test Flexibility

Once you have the suit on, put it through some full range of motion tests. Squat down, fully extend your arms overhead, and practice swimming motions – this will reveal any flexibility or mobility issues with that particular size and style.

5. Consider Special Transition Features

Higher-end wetsuits often have special features like zippers at the ankles or shoulders to make removal easier and faster during transitions. If quick transitions are a priority, look for these design details.

6. Ask for Fitting Advice

If you are trying on suits at a retail store, don’t hesitate to ask the staff for sizing recommendations and feedback. A second set of eyes may spot potential fit issues you can’t see yourself. Their expertise can be invaluable.

A perfectly fitted wetsuit should feel snug but not restrictive as you move. It will flex and stretch fluidly with your body, almost like a second skin. Taking the time to dial in the fit will help you glide effortlessly through the water.

Common Wetsuit Sizing Mistakes to Avoid

A more experienced triathlete stands beside them, pointing at the chart with a concerned expression, suggesting that they should consider more factors than just the height/weight. Around them, there are racks filled with various wetsuits, some with bold colors and trendy designs.

Now that we’ve covered the key basics let’s explore some common wetsuit sizing mistakes that rookie and veteran triathletes alike frequently make:

1. Relying Too Heavily on Height/Weight Charts

Many wetsuit manufacturers provide general height/weight charts to help guide sizing selections. While these can provide a reasonable starting point, you cannot rely on them alone. 

Factors like your specific body type, proportions, swim stroke style, race distance, and water temperature also significantly impact finding the optimal fit.

2. Prioritizing Style Over Functionality

It’s tempting to opt for the trendy sleeveless suit or bold, colorful designs. But when wetsuit shopping, remember to prioritize key performance features like warmth, buoyancy, and flexibility first and foremost. The form should follow function when it comes to wetsuits.

3. Ignoring Care and Maintenance Guidelines

Neoprene wetsuits require proper care to maximize lifespan. Be sure to rinse suits thoroughly with fresh water after use, limit direct sun exposure, use wetsuit-specific shampoos and storage bags, and avoid improper storage techniques. Follow all manufacturer care instructions.

4. Failing to Consider Future Progression

When investing in a triathlon wetsuit, don’t just think about your next race but your long-term progression goals as well. It’s worth purchasing a high-quality wetsuit designed for more advanced distances and conditions that allows room for you to grow as your experience level increases over multiple seasons.

By being mindful of these common pitfalls, you can avoid missteps and dial in a wetsuit that not only fits you flawlessly now but will continue to serve you well as you tackle more challenging triathlons in the future.

Conclusion

In conclusion, choosing the correct wetsuit size for a triathlon is vital for optimal performance. It should fit snugly, offering buoyancy and flexibility. Take precise body measurements, evaluate wetsuit materials, consider race conditions, and try different suits. Avoid solely relying on generic size charts and emphasize function over style. 

The perfect wetsuit enhances your swimming efficiency, ensuring you achieve your triathlon objectives. Remember, the right fit is key. So, when you question your wetsuit size, you’ll know how to approach it. Best of luck in your races!
