While a cool print or a vibrant color is a nice bonus, it’s the hidden details that truly define a great training suit. The real performance comes from the technology woven into the fabric, the way the seams are stitched to prevent chafing, and how strategic paneling creates a hydrodynamic fit. These are the elements that impact your comfort, your speed, and how long your suit will last. This guide goes beyond the surface to explore the technical side of swimwear. We’ll explain what features like compression, flatlock seams, and chlorine-resistant fabrics actually do for you in the water. You’ll learn how to choose training swimming suits based on smart design and superior function, not just looks.
Key Takeaways
- Focus on the Fabric First: A suit's performance and lifespan depend entirely on its material. Choose chlorine-resistant fabrics like polyester or PBT blends to ensure your suit holds its shape, color, and supportive fit through countless training sessions.
- Treat Fit as a Performance Feature: The right fit should feel like a second skin—snug and compressive without restricting your movement. Consider how different back styles and leg cuts will affect your mobility and support to find a suit that works with your stroke, not against it.
- Make Your Suit Last with Proper Care: Extend the life of your investment by rinsing it in cool, fresh water immediately after every swim. Gently squeeze out the water and lay it flat to dry away from direct sun and heat to preserve the fabric's integrity.
What Makes a Training Suit Great?
When you’re in the water multiple times a week, your training suit becomes your most important piece of gear. It’s more than just something to wear; it’s a tool that can affect your comfort, your confidence, and even your performance. But what separates a fantastic training suit from one that gets relegated to the back of your drawer? It comes down to a few key elements that work together to support you through every lap, drill, and set.
A great training suit is built to handle the demands of your routine. It needs to stand up to harsh pool chemicals without losing its shape or color. It has to move with you, offering total freedom of movement whether you’re perfecting your butterfly stroke or leading a water aerobics class. Durability is also crucial—you want a suit that will last through countless hours of hard work. Finally, practical features like quick-drying fabric make your life easier both in and out of the pool. Let’s look at what makes these features so important.
Why Chlorine Resistance Matters
If you’ve ever seen a regular swimsuit fade, sag, and practically disintegrate after a few weeks in the pool, you know the destructive power of chlorine. Your training suit is constantly exposed to it, which is why chlorine resistance is non-negotiable. The best competitive swim suits are made from high-quality, chlorine-resistant fabrics, often a blend of polyester and PBT (polybutylene terephthalate). These materials are specifically engineered to withstand chemical exposure, so your suit will maintain its color, elasticity, and fit for much longer than one made from standard nylon or spandex. This means you can count on it to perform consistently, practice after practice.
Find a Suit That Moves With You
Your suit should feel like a second skin, not a straitjacket. The right fabric and construction will allow for a complete range of motion, so you never feel restricted. A suit that pinches, chafes, or rides up is a distraction you don’t need. Understanding the fundamentals of swimwear fabric is the first step toward choosing a suit that feels amazing and performs beautifully. Whether you’re reaching for the wall on a final sprint or stretching in a fitness class, your suit needs to provide support without getting in your way. It should move with your body, not against it.
Choose a Suit Built to Last
A training suit is an investment in your sport, and you want it to last. Durability goes beyond just chlorine resistance. It’s about how the suit holds its shape after repeated wear and washing, the quality of the stitching, and its resistance to pilling. The combination of materials like polyester and nylon creates a powerful mix of durability and flexibility. When you choose a well-made suit from our swimwear new arrivals, you’re getting a piece of gear that’s designed to keep up with you, session after session, without stretching out or wearing thin.
Opt for Quick-Drying Fabrics
No one enjoys packing a soggy, heavy swimsuit into their bag or putting on a still-damp suit for a second practice of the day. This is where quick-drying fabric makes a huge difference. High-quality materials used in modern swim gear are designed to shed water efficiently, allowing your suit to dry much faster. This isn’t just a matter of convenience; it also helps prevent the growth of mildew and keeps your suit feeling fresh. A quick-drying suit is more comfortable to wear post-swim and is ready to go when you are.

Which Style of Training Suit is Right for You?
Finding the perfect training suit is a lot like finding the perfect pair of running shoes—what works for one person might not work for another. The right style comes down to your activity, your body, and what makes you feel most comfortable and confident in the water. Whether you're logging miles for a competition or enjoying a water aerobics class, the cut of your suit plays a huge role in your performance and comfort. Let's look at the most common styles to help you find the one that fits your needs, so you can focus on your stroke, not on adjusting your straps.
The Classic One-Piece
The one-piece is the workhorse of the swimming world for a reason. It’s a staple for serious swimmers because it offers a streamlined, second-skin fit that reduces drag and helps you glide through the water. When you’re focused on a tough training set, the last thing you want to worry about is your suit shifting. A well-designed one-piece provides excellent coverage and support, staying securely in place through every flip turn and dive. Modern competitive swimwear is engineered with performance fabrics that offer both comfort and durability, making the classic one-piece a reliable choice for rigorous, consistent training.
Flexible Two-Piece Suits
If you love the freedom of a two-piece, you don't have to give it up for training. Modern athletic two-pieces are built for performance, offering a secure fit that can handle intense workouts. Their biggest advantage is versatility. You can mix and match top and bottom sizes to get a perfect, customized fit for your body. This style also provides incredible freedom of movement, which many swimmers prefer, especially for long practices. Made from high-quality, stretchy materials, these suits offer excellent support and are a fantastic option for both serious training and more casual swims. Check out the latest swimwear new arrivals to see designs that stay put.
Tankini Styles for Versatile Coverage
The tankini is the ultimate hybrid, giving you the best of both worlds. It combines the modest coverage of a one-piece with the convenience and flexibility of a two-piece. This makes it a popular choice for swimmers who want a bit more coverage around the midsection without feeling restricted. Tankinis are perfect for activities like water aerobics, where you’re moving in all different directions and want a suit that moves with you. Crafted from durable, comfortable fabrics, a good training tankini allows for a full range of motion while providing the support you need to feel secure and confident during your workout.
Choosing the Right Back Style
The back of your swimsuit is more than just a fashion statement—it’s a key performance feature. The right back style can significantly impact your mobility and comfort in the water. Designs with thin straps and an open back, like a V-back or flyback, offer maximum shoulder flexibility, which is great for swimmers with long, powerful strokes. Styles with wider straps and more coverage, such as a racerback, provide more support and are often preferred for their secure, locked-in feel. When looking at new products, consider how different back designs might complement your swimming technique and personal comfort preferences.
How Fabric Affects Your Performance
The material of your training suit is one of the most important factors in how it performs lap after lap. It’s not just about how the suit looks; the right fabric can reduce drag, withstand harsh pool chemicals, and give you the flexibility you need to perfect your stroke. Think of your swimsuit as a piece of high-performance equipment. The technology woven into the fibers directly impacts your comfort and efficiency in the water. When you’re looking at a new suit, paying attention to the fabric composition will help you find one that feels great and holds up to your training schedule. From chlorine-resistant polyester to flexible spandex blends, each material offers a unique set of benefits designed to help you meet your goals.
A Look at Advanced Fabric Tech
Modern training suits are packed with fabric technology designed to give you an edge. These aren't your average beach day fabrics; they are engineered to enhance speed and provide a second-skin fit that minimizes drag. The goal is to create a suit that feels like it’s barely there, allowing you to move through the water with less resistance. Advanced materials often feature water-repellent properties, which prevent the suit from getting waterlogged and heavy. This focus on hydrodynamic design is crucial for competitive swimmers who measure success in fractions of a second. You can see this innovation in many of the new products hitting the market.
The Benefits of Endurance+ and CREORA® HighClo™
If you spend a lot of time in a chlorinated pool, you know how quickly it can destroy a swimsuit. That’s where high-performance fabrics like Endurance+ and CREORA® HighClo™ come in. These materials are specifically engineered to resist the damaging effects of chlorine and UV exposure, which means your suit will maintain its shape, color, and compression for much longer. A durable suit provides consistent performance, so you can focus on your workout instead of worrying about your gear stretching out or fading. Investing in a suit made with these long-lasting fabrics means you get more value and more training sessions out of your purchase.
Polyester vs. Blends: What's the Difference?
When you check the tag on a training suit, you’ll usually see polyester or a blend of materials. So, what’s the difference? 100% polyester suits are the workhorses of the swim world—they’re incredibly durable and offer the best resistance to chlorine and fading. However, they can have less stretch. Fabric blends, which often mix polyester with spandex, nylon, or polyurethane, offer a powerful combination of durability and flexibility. These blends provide enhanced stretch and comfort, making them a great choice for long, rigorous training sessions. Many of our women's new arrivals feature these comfortable, high-performance blends.
Why Stretch and Recovery Matter
Have you ever worn a suit that felt great on the first wear but turned into a baggy mess after a few swims? That’s an issue of poor stretch and recovery. "Stretch" refers to how much the fabric can extend, while "recovery" is its ability to snap back to its original shape. Excellent stretch and recovery are vital for a training suit because they allow for a full range of motion without sacrificing a snug, supportive fit. This ensures your suit moves with you on every stroke, kick, and turn. A suit that holds its shape provides consistent compression and coverage, which is essential for both comfort and peak performance.
What Design Features Help You Swim Faster?
Beyond the fabric, a suit's construction makes a huge difference in your speed and comfort. The best training suits use smart design features that reduce drag and help you move more efficiently through the water.
Sleek, Hydrodynamic Designs
A hydrodynamic design minimizes resistance in the water. The goal is a sleek, second-skin fit that doesn't bunch or sag, as this creates drag and slows you down. The fabric and cut of a suit are essential for this effect. High-performance competitive swimwear is engineered to hug your body, allowing you to slice through the water with less effort. This streamlined silhouette is your first step toward a faster swim.
Flatlock Seams for Chafe-Free Comfort
Nothing ruins a workout faster than chafing. Quality training suits use flatlock seams to prevent this. Unlike traditional raised seams that can rub against your skin, flatlock seams lie flat, creating a smooth surface that prevents irritation. This detail makes a huge impact on comfort during long sessions. It allows for a full range of movement without distraction, so you can focus on your form instead of an uncomfortable suit.
The Role of Strategic Paneling
Top-tier swimsuits use strategic paneling—multiple pieces of fabric stitched together—to create a superior fit. These panels are designed to follow the natural contours of your body, enhancing support and reducing drag. By combining materials like durable polyester and flexible nylon, designers can place compression and stretch exactly where you need it most. This construction helps you glide more efficiently through the water with every single stroke.
Finding the Right Support and Compression
A great training suit should feel like a supportive hug. For women, features like built-in bras provide essential bust support for confident movement. Compression is another key feature for all swimmers. A snug, compressive fit helps stabilize muscles, which can reduce fatigue and improve blood flow. The suit shouldn't be uncomfortably tight, but it should hold you in securely. Many of our women's new arrivals feature this perfect balance of support and compression.
How Should a Training Suit Fit?
Finding the right training suit is all about the fit. Unlike casual swimwear, a training suit is a piece of technical equipment designed to help you perform your best. It should feel like a second skin—snug and compressive, but never restrictive. When you try on a suit, it should lie flat against your body without any sagging or wrinkling, especially around the torso and rear. If you can pinch a fold of fabric, it’s likely too big. On the other hand, if the straps are digging into your shoulders or you feel like your range of motion is limited, it’s too small.
For serious swimmers, performance trumps vanity sizing. Many competitive athletes prefer to size down to get that ultra-snug, compressive fit that reduces drag and prevents the suit from scooping up water. Remember that swimsuits always feel tighter when they’re dry and will loosen up slightly in the water. The perfect fit gives you the confidence to focus on your stroke, not on adjusting your suit. Finding that sweet spot between compression and comfort is key to getting the most out of every training session.
Sizing Tips for Every Body Type
A training suit should fit snugly all over. When you try one on, check for any gaps around the neckline, armholes, or leg openings—these are signs the suit is too large and will create drag in the water. The fabric should be taut across your back. A good test is to pull the straps up toward your ears; they shouldn't stretch past your earlobes. For many swimmers, especially those looking for a performance edge, sizing down is common practice to ensure the most secure fit. Your new training suit should feel comfortably tight, allowing you to move freely without any chafing or shifting as you swim.
Choosing Support for Your Bust Size
The right amount of support can make a huge difference in your comfort and focus during a workout. The back style of a suit is the biggest factor here. Designs like a racerback provide excellent bust support by pulling the fabric taut across the chest, making them a great choice for a more comfortable swim. If you need extra support, look for suits with thicker straps or a built-in shelf bra. For swimmers with a smaller bust, thinner straps and more open-back styles can offer greater flexibility and freedom of movement without sacrificing the support you need. It’s all about finding the design that feels best for your body.
Leg Cut Options for Better Range of Motion
The cut of the leg opening affects both coverage and mobility. Training suits typically come in three cuts: high, medium, and conservative. If you want maximum freedom of movement for your legs and hips, a suit with a high leg cut and an open back is your best bet. This style is popular among competitive swimmers because it allows for a full range of motion during kicks. A medium or moderate cut offers a great balance of coverage and flexibility, making it a versatile choice for general training and fitness swimming. A conservative cut provides the most coverage and is often preferred for activities like water aerobics.
The Best Suits for Your Activity
Not all training suits are created equal, and the best one for you really depends on how you plan to spend your time in the water. Whether you're chasing a new personal best, getting in a low-impact workout, or training for three events at once, your suit's design and fabric can make a huge difference. Let's look at what to prioritize for your specific activity.
For the Competitive Swimmer
When your focus is on speed, every detail of your suit matters. The best competitive swimwear is engineered for performance, using a powerful mix of polyester, nylon, and polyurethane. This combination creates a durable, flexible fabric that fits like a second skin, reducing drag and allowing for a full range of motion. Added stretch and strong support are key features that help you perform at your peak, giving you the confidence to push for that new personal best. A snug, compressive fit is essential for slicing through the water with minimal resistance.
For Water Aerobics and Fitness
If your training involves regular fitness classes or lap swimming, you need a suit that can keep up. For water aerobics and general fitness, prioritize comfort and durability. Look for suits made from chlorine-resistant polyester blends that won’t fade or lose their shape after just a few months in the pool. A great fitness suit allows for a complete range of movement, so you can stretch, jump, and twist without feeling restricted. When your suit fits well and feels good, you can focus entirely on your workout and stay motivated session after session.
For the Triathlete
Triathletes demand incredible versatility from their gear, and their swimwear is no exception. The ideal suit needs to perform in the water without hindering you on the bike or run. Nylon-spandex blends are a fantastic choice, offering the perfect balance of stretch, support, and durability. This fabric moves with you, providing a comfortable, secure fit that reduces drag during the swim. For open-water training and races, many athletes also rely on high-quality wetsuits to provide buoyancy and thermal protection, ensuring they can perform their best from start to finish.
How to Get the Best Value for Your Budget
Finding the right training suit is about more than just the initial price tag. It’s about getting a suit that works as hard as you do, lap after lap, without stretching out or fading after a few weeks. A great suit is an investment in your training, and getting the best value means finding that sweet spot where durability, performance, and price all meet. Whether you’re a competitive swimmer logging serious hours or someone who enjoys a weekly water aerobics class, you deserve a suit that fits your budget and your goals. Let’s look at how you can make a smart purchase that will serve you well.
Balancing Price and Performance
You don’t have to choose between a suit that performs well and one that fits your budget. The key is to focus on the fabric. The best training suits are often made from durable, chlorine-resistant materials like polyester or polyester blends. While they might cost a little more upfront than a basic Lycra suit, they hold their shape and color far longer, saving you money over time. Think of it this way: buying one quality competitive swim suit that lasts a whole season is much more cost-effective than buying three cheaper ones that wear out quickly. When you shop, check the material composition to ensure you’re getting a suit built for the rigors of training in a pool.
When to Invest in Premium Features
For swimmers who spend a lot of time in the water, investing in a suit with premium features can be a game-changer. We’re talking about advanced fabric technologies that offer superior stretch and recovery, strategic compression to support your muscles, and hydrodynamic designs that reduce drag. These high-performance suits often use a powerful mix of materials like polyester, nylon, and spandex to create a second-skin fit that’s both durable and flexible. If you’re training for a competition or simply want to get the most out of every workout, the added cost for these features often translates directly into better comfort and performance in the water. Check out the new products to see the latest innovations.
Make Your Suit Last: Care and Maintenance Tips
The single best way to get more value from your suit is to take good care of it. Even the most durable fabric will break down if not treated properly. After every swim, rinse your suit immediately in cool, fresh water to wash away chlorine and other chemicals. Gently squeeze out the excess water—never wring it—and lay it flat to dry in a shady, well-ventilated spot. Avoid the washing machine and dryer at all costs, as the heat and agitation will destroy the delicate fibers. A few minutes of care after each use will dramatically extend the life of your suit, keeping the fit snug and the colors bright. This simple routine helps you get the most out of every suit you buy, even one you find in the Clearance Corner.

When you're putting in hours at the pool, the last thing you want to worry about is your suit. The best training suits are the ones you forget you're wearing—they're durable, comfortable, and move with you. Investing in a high-quality suit is one of the smartest moves you can make for your swimming. A great training suit is typically made from durable, chlorine-resistant polyester blends. This material composition is crucial because it stands up to the harsh chemicals in pool water, preventing the fabric from breaking down and losing its shape. This means your suit will fit like new for much longer, providing consistent support and compression lap after lap.
Beyond durability, the right fabric offers flexibility and elasticity, allowing for a full range of motion without feeling restrictive. This is essential for perfecting your stroke and getting the most out of your training sessions. A well-designed suit also features a snug, hydrodynamic fit that reduces drag in the water, helping you feel faster and more efficient.

Frequently Asked Questions
My new training suit feels really tight. Is it too small? A snug fit is exactly what you want in a training suit, so it probably fits just right. It should feel like a firm hug or a second skin. Remember that suits always feel tighter when they're dry and will relax a bit once you're in the water. As long as the straps aren't digging into your shoulders and you can move your arms and legs freely without restriction, you've likely found the perfect size.
How do I know when it's time to replace my training suit? There are a few tell-tale signs that your suit has put in its last lap. If you can see through the fabric when you stretch it, especially around the chest or rear, it's time for a new one. You'll also notice the material feels thinner, lighter, and less compressive. A suit that has lost its elasticity will start to feel baggy and may scoop up water when you push off the wall, which is another clear sign it's ready for retirement.
What's the most important thing to look for if I'm on a tight budget? If you want the best value, focus on the fabric content. Look for a suit with a high percentage of polyester, as this material offers the best resistance to chlorine. A durable, chlorine-resistant suit will hold its shape and color for much longer than a standard fashion swimsuit, meaning you won't have to replace it nearly as often. It's a smart investment that saves you money in the long run.
Can I wear my training suit for a race? Absolutely. A well-fitting training suit is perfectly fine for most competitions, especially for developmental meets or if you're just starting out. Many brands, like JOLYN, are even FINA-approved. The main difference is that elite "tech suits" are made with water-repellent fabrics and advanced compression for maximum speed, but they are much less durable and are saved for championship meets.
Besides rinsing it, what's the best way to care for my suit? After rinsing your suit in cool, fresh water, gently squeeze out the excess water—never twist or wring it out, as this damages the fibers. Then, lay it flat or hang it to dry in a well-ventilated area away from direct sunlight, which can fade the colors and break down the fabric. The most important rule is to keep it out of the washing machine and especially the dryer, as the heat will ruin its elasticity.
