What to Wear Under Wetsuit for Triathlon

When it comes to triathlons, wearing the right gear can make all the difference in your performance and comfort. One essential piece of gear is the wetsuit, which helps you stay warm and buoyant during the swim portion of the race. But what should you wear under your wetsuit?

First and foremost, it’s important to choose clothing that is quick-drying. Wetsuits are designed to keep you warm, not dry, so any clothing you wear underneath will get wet. Opting for materials like cotton will leave you feeling damp and uncomfortable throughout the race. Instead, consider wearing a tri suit, which is designed to dry quickly and provide comfort during all three legs of the race.

When choosing a tri suit, it’s important to consider factors like weather and personal preference. Some tri suits are one-piece, while others are two-piece. Some offer more padding or compression than others. Ultimately, the goal is to find a suit that fits well, feels comfortable, and allows you to move freely throughout the race. With the right clothing underneath your wetsuit, you’ll be ready to tackle the swim portion of your next triathlon with confidence.


Understanding Wetsuits for Triathlons

As a triathlete, wetsuits are an essential part of your gear. They help you stay warm, buoyant, and reduce drag in the water. In this section, I will cover the basics of wetsuits for triathlons, including materials, types, fit, and temperature considerations.


Wetsuit Materials and Technologies

Most wetsuits for triathlons are made of neoprene, a synthetic rubber that is insulating, flexible, and buoyant. However, not all neoprene is created equal. Some wetsuits use high-quality neoprene that is more stretchy and durable than others. Additionally, some wetsuits feature special technologies, such as coated neoprene, that reduce drag and increase buoyancy.


One-Piece vs. Two-Piece Wetsuits

Wetsuits for triathlons come in two main styles: one-piece and two-piece. One-piece wetsuits are a single unit that covers the entire body, while two-piece wetsuits consist of separate tops and bottoms. One-piece wetsuits are generally better for colder water and provide more coverage, while two-piece wetsuits are more versatile and allow for easier bathroom breaks.


Wetsuit Fit and Sizing

The fit of your wetsuit is crucial for comfort and performance. A wetsuit that is too loose will allow water to seep in, reducing its insulating properties, while a wetsuit that is too tight will restrict your movement and cause discomfort. When choosing a wetsuit, make sure to consult the manufacturer’s sizing chart and try it on before purchasing. It’s also important to note that wetsuits will stretch slightly over time, so a snug fit is preferable.


Temperature and Thickness

The temperature of the water is a crucial factor to consider when choosing a wetsuit. Most triathlon events have rules regarding wetsuit usage based on water temperature. If the water temperature is below a certain threshold, wetsuits may be mandatory, while if it’s above a certain threshold, wetsuits may be prohibited. Additionally, wetsuits come in different thicknesses, ranging from 2mm to 5mm, with thicker wetsuits providing more insulation but less flexibility. It’s important to choose a wetsuit that is appropriate for the water temperature and your personal preferences.

Overall, understanding the basics of wetsuits for triathlons is crucial for choosing the right gear and performing your best in the water. By considering factors such as materials, types, fit, and temperature, you can choose a wetsuit that is comfortable, functional, and helps you achieve your goals.


Choosing the Right Undergarments

When it comes to wearing the right undergarments under a wetsuit for a triathlon, there are a few things to consider. In this section, I’ll discuss the importance of choosing the right undergarments, as well as some key features to look for when selecting your gear.


Triathlon-Specific Undergarments

One of the most important things to consider when choosing undergarments for a triathlon is to opt for triathlon-specific apparel. Tri suits are designed to be worn under a wetsuit and can be a great option for those looking to save time in transition. They are made from materials that are quick-drying, breathable, and moisture-wicking, which can help keep you comfortable during the race.


Comfort and Support Features

Another important consideration when choosing undergarments is comfort and support. Look for undergarments that offer a snug fit without being too tight, as this can help prevent chafing and discomfort during the race. Additionally, look for undergarments that offer support for your muscles, as this can help reduce fatigue and improve performance.


Material Considerations

When it comes to material, look for undergarments made from materials that are quick-drying, breathable, and moisture-wicking. These materials can help keep you comfortable and dry during the race, which can be especially important during longer events. Additionally, consider the thickness of the material, as thicker materials may provide more warmth but can also be less flexible and more restrictive.

Overall, choosing the right undergarments for a triathlon can be an important part of your race day preparation. By opting for triathlon-specific apparel, looking for comfort and support features, and considering material options, you can help ensure that you stay comfortable and perform your best during the race.


Transitioning Between Segments

As a triathlete, transitioning between segments is a crucial aspect of the race. It can be the difference between a successful race and a disappointing one. In order to have a smooth transition, it is important to consider what to wear under your wetsuit.


Quick-Drying Solutions

One of the most important things to consider when choosing what to wear under your wetsuit is the material. It is essential to wear quick-drying, breathable fabrics. This will help prevent chafing and make you more comfortable during the race. A wet tri suit can be very uncomfortable on a 40k bike ride in the wind.


Ease of Movement in Transitions

Another important thing to consider is ease of movement during transitions. You want to wear something that is easy to take off and put on quickly. This is where a tri-suit comes in handy. Wearing a tri-suit from start to finish can save you precious seconds in transition. A two-piece tri-suit is also a good option, as it makes mid-race bathroom breaks easier. However, two-piece suits are less aerodynamic and the top can ride up.


Clothing for Bike and Run Segments

It is also important to consider what you will wear for the bike and run segments of the race. The clothing you choose should be comfortable and allow for ease of movement. Tri-specific shorts and a tri top are a good option for the bike and run segments. They are designed to dry quickly and provide good ventilation.

Overall, choosing what to wear under your wetsuit is an important decision that can impact your race. Quick-drying fabrics, ease of movement, and comfortable clothing for the bike and run segments of the race are all important factors to consider.


Preventing Discomfort and Chafing

When it comes to triathlon wetsuits, preventing discomfort and chafing is crucial to ensure a successful race. Here are a few tips on how to avoid chafing and irritation while wearing a wetsuit during a triathlon.


Strategic Padding and Seams

One way to prevent chafing is to choose a wetsuit with strategic padding and seams. Padding can provide extra cushioning between your skin and the wetsuit, reducing the risk of chafing. Look for wetsuits with padding in areas that are more prone to chafing, such as the neck, underarms, and crotch. Seams can also cause irritation, so choose a wetsuit with flatlock or glued and blind-stitched seams, which are less likely to rub against your skin.


Layering Techniques

Layering can also help prevent chafing and irritation. Consider wearing a thin layer of clothing under your wetsuit, such as a triathlon suit or a rash guard. This can provide an extra barrier between your skin and the wetsuit, reducing friction and irritation. Make sure the layer fits snugly and doesn’t bunch up or ride up during the race.


Anti-Chafing Products

Another way to prevent chafing is to use anti-chafing products. These can include lubricants, powders, and creams. Apply the product to areas prone to chafing, such as the neck, underarms, and crotch, before putting on your wetsuit. Look for products that are specifically designed for use during triathlons, as they are often waterproof and long-lasting.

By following these tips, you can reduce the risk of discomfort and chafing while wearing a wetsuit during a triathlon. Remember to choose a wetsuit with strategic padding and seams, consider layering, and use anti-chafing products to ensure a successful race.


Performance Enhancements

Aerodynamics and Hydrodynamics

When it comes to triathlon, every second counts. That’s why I always think about aerodynamics and hydrodynamics when choosing what to wear under my wetsuit. I want to make sure that I’m as streamlined as possible in the water, so I can swim faster and more efficiently.

One thing to keep in mind is that any extra fabric or loose clothing can create drag in the water. That’s why I prefer to wear a tri suit under my wetsuit. Tri suits are designed to be tight-fitting and streamlined, which can help reduce drag and improve your hydrodynamics.

Another thing to consider is your hair. Long hair can create drag in the water, so I always wear a swim cap to keep my hair out of my face and reduce drag.


Compression and Buoyancy

Compression and buoyancy are two other factors that can affect your performance in the water. Compression garments can help improve your circulation and reduce muscle fatigue, which can help you swim faster and longer.

Buoyancy is also important, especially if you’re not a strong swimmer. Wearing a wetsuit can help improve your buoyancy and make it easier to stay afloat in the water.

When choosing what to wear under your wetsuit, consider wearing compression shorts or tights to improve your circulation, and a tri suit or wetsuit to improve your buoyancy.


Swim-to-Bike Transition Gear

Finally, don’t forget about your swim-to-bike transition gear. When you’re coming out of the water and getting ready to hop on your bike, you want to make sure that you’re dressed appropriately for the bike leg of the race.

I like to wear a tri suit under my wetsuit, so I’m already dressed for the bike leg when I come out of the water. I also make sure to have my bike shoes and helmet set up in the transition area, so I can quickly change out of my wetsuit and into my bike gear.

By thinking about aerodynamics, hydrodynamics, compression, buoyancy, and transition gear, you can improve your performance in the water and make your triathlon experience more enjoyable.


Practical Considerations

Ease of Use and Bathroom Breaks

When it comes to choosing what to wear under a wetsuit for a triathlon, practicality should be a top priority. I prefer to wear a triathlon suit under my wetsuit because it’s a one-piece outfit that’s easy to put on and take off. This is especially important during transitions when every second counts. Additionally, triathlon suits are designed to be quick-drying, which is essential for staying comfortable during the bike and run portions of the race.

Another practical consideration is bathroom breaks. Yes, it’s not the most glamorous topic, but it’s something that all triathletes have to deal with. Wearing a one-piece triathlon suit means that you won’t have to fully undress when nature calls. This can save you valuable time and help you maintain your focus during the race.


Mix and Match Triathlon Kits

While I prefer to wear a triathlon suit under my wetsuit, some athletes choose to mix and match their triathlon kit. For example, you might wear a triathlon top and shorts under your wetsuit. This can be a good option if you prefer the fit or style of a particular brand or if you already own a triathlon kit that you’re comfortable in.

However, it’s important to keep in mind that mixing and matching your kit can lead to chafing or discomfort. Make sure that the pieces you choose fit well and don’t rub against your skin. You don’t want to be distracted by a sore spot during the race.


Budget and Personal Preference

Finally, your budget and personal preference will play a role in what you choose to wear under your wetsuit. Triathlon suits can be expensive, so if you’re on a tight budget, you might opt for a cheaper option like a pair of triathlon shorts and a tank top.

Similarly, personal preference will play a role in what you choose to wear. Some athletes prefer the feeling of a one-piece suit, while others like the flexibility of a two-piece kit. Ultimately, the most important thing is that you feel comfortable and confident in your choice.
