For any serious athlete, every piece of equipment matters. You optimize your goggles for visibility and your fins for power, so why should your apparel be any different? A high-performance rashguard is more than just a shirt; it’s a tool that can enhance your training. The compressive fit of many men's rashguards helps reduce drag in the water, supports your muscles, and prevents the chafing that can become a major distraction during a long open-water swim or triathlon. This guide is for the athlete looking to gain an edge by choosing gear that works as hard as they do, covering everything from performance-enhancing materials to the perfect competition fit.
Key Takeaways
- A great rashguard is technical gear: Look for key features like a UPF 50+ rating for sun protection, flatlock stitching to prevent chafing, and quick-drying fabric for comfort in and out of the water.
- Match the fit to your activity for better performance: A snug, form-fitting style reduces drag for competitive swimming and surfing, while a relaxed fit offers more comfort for casual activities like paddleboarding or beach days.
- Proper care extends the life of your gear: Make your rashguard last by always rinsing it in cool, fresh water after use, washing it by hand with a mild soap, and letting it air dry completely to preserve its shape and protective qualities.
What is a Men's Rashguard (And Why Do You Need One)?
If you think a rashguard is just a fancy swim shirt, it's time to take a closer look. A men's rashguard is a versatile piece of athletic wear made from synthetic fabrics like spandex, nylon, or polyester. Originally designed for surfers to prevent chest rash from their boards, these shirts have become essential gear for almost any water activity. Whether you're a competitive swimmer, a triathlete, or just enjoying a day at the beach, a good rashguard offers a powerful combination of protection, comfort, and performance.
Unlike a standard cotton t-shirt that gets heavy and saggy when wet, a rashguard is designed to perform in the water. It fits snugly against your body to reduce drag, wicks moisture away to keep you comfortable, and dries quickly once you're out of the water. It acts like a second skin, protecting you from the sun, chafing, and scrapes. From intense training sessions in the pool to open-water swims and paddleboarding, adding a rashguard to your gear bag is one of the smartest moves you can make for your skin and your performance.
Protect Your Skin from the Sun
One of the biggest reasons to wear a rashguard is for sun protection. Spending hours in the water means double the sun exposure, from the direct rays above and the reflected rays off the water's surface. Most high-quality rashguards come with a UPF (Ultraviolet Protection Factor) rating, often UPF 50+. This means the fabric is engineered to block over 98% of the sun's harmful UVA and UVB rays, significantly reducing your risk of sunburn and long-term skin damage. It’s like wearing a powerful, full-coverage sunscreen that doesn't wash off in the water, giving you reliable protection for your entire session.
Stay Comfortable and Dry
Comfort is key when you're active, and that's where rashguard material truly shines. Made from lightweight, stretchy fabrics, a rashguard moves with you, never restricting your motion in the water. The material is also moisture-wicking, which means it pulls sweat and water away from your skin and helps it evaporate quickly. This keeps you from feeling waterlogged and cold during your swim or workout. The secure, athletic fit also ensures your shirt won't ride up or balloon out while you're moving, so you can stay focused on your activity without any distractions.
Prevent Chafing and Irritation
The name says it all: a rashguard guards against rashes. It creates a protective barrier between your skin and anything that might cause irritation, whether it's a surfboard, a life vest, or even the seams of a wetsuit. Quality rashguards are constructed with flatlock stitching, where the seams lie flat against the fabric instead of sticking up. This small detail makes a huge difference in comfort, preventing the rubbing and chafing that can cut a day on the water short. It’s an essential feature for anyone prone to skin irritation during long sessions.
Improve Performance with Compression
For athletes, a rashguard can be more than just a protective layer; it can be a piece of performance gear. Many rashguards offer a compressive fit, which provides gentle pressure on your muscles. This compression can help improve blood flow, reduce muscle vibration, and potentially decrease fatigue during intense training. For competitive swimmers and triathletes, this can mean more efficient workouts and faster recovery times. The snug fit also reduces drag in the water, helping you feel sleeker and faster with every stroke.
What Are the Different Types of Rashguards?
When you start shopping for a rashguard, you'll quickly see they come in all shapes, styles, and materials. It’s not just about picking a color you like; the right rashguard depends on what you’re doing in the water, how much sun protection you need, and what feels most comfortable. Understanding the key differences will help you choose the perfect one for your next aquatic adventure. Let's break down the main types so you can find a rashguard that works as hard as you do.
Long Sleeve vs. Short Sleeve
The most obvious choice you'll make is sleeve length. A long-sleeve rashguard offers the most coverage, making it your best friend for long days under the sun or for activities like surfing where you need extra protection from board rash. If you're prone to sunburns, this is the way to go. On the other hand, a short-sleeve rashguard gives your arms more freedom and can feel a bit cooler. It’s a great choice for a quick swim, a game of beach volleyball, or for anyone who prefers a less restrictive feel. Many of our new rashguards come in both styles, so you can choose based on the day's plan.
Fitted vs. Relaxed Fit
Next up is the fit. Rashguards generally come in two styles: fitted or relaxed. A fitted rashguard is snug, almost like a second skin. This design is perfect for performance-focused activities like competitive swimming or surfing because it reduces drag in the water and won't bunch up while you move. A relaxed-fit rashguard, often called a surf tee, fits more like a standard t-shirt. It’s comfortable, breathable, and perfect for more casual activities like paddleboarding, kayaking, or just lounging by the pool. The choice really comes down to balancing performance needs with personal comfort. You can explore our men's new arrivals to see examples of both fits.
Understand Rashguard Materials
The fabric of your rashguard is what makes it so effective. Most are made from a blend of synthetic fibers like polyester, nylon, and spandex. This combination creates a lightweight, stretchy, and quick-drying material that moves with you. Some high-performance rashguards also incorporate compression technology. This feature provides gentle pressure on your muscles, which can help reduce fatigue and support recovery during intense training sessions. When you're looking for gear to support your competitive swimming, paying attention to the material can make a real difference in your comfort and endurance in the pool.
Match Your Rashguard to Your Activity
Ultimately, the best rashguard is the one that suits your specific activity. If you're a triathlete or open-water swimmer, a tight-fitting, long-sleeve rashguard will give you sun protection without creating drag. For a day of surfing, that same style will protect you from the sun and your board. If you're heading to a water aerobics class, you might prefer a short-sleeve, relaxed-fit shirt that allows for maximum arm movement. For casual beach days, any style that keeps you comfortable and protected works. Think about what you'll be doing most, and choose the features that will support you best.
Our Top Picks for Men's Rashguards
With so many options out there, finding the right rashguard can feel like a challenge. But it really comes down to what you need it for. Are you spending all day under the sun, training for a triathlon, or just looking for a comfortable shirt for a beach day? We’ve broken down our top picks based on what matters most, so you can find the perfect one for your next water adventure.
For Maximum Sun Protection
If you’re spending hours in the sun, skin protection is non-negotiable. Look for a rashguard with a UPF 50+ rating, the highest level of sun protection available in fabric. It blocks the vast majority of harmful UV rays and, unlike sunscreen, it won't wash off in the water. This makes it essential gear for surfers, paddleboarders, and anyone enjoying a long day outdoors. Many of our newest rashguards feature this built-in protection, so you can focus on the fun, not the sunburn.
For High-Performance Competition
When you’re focused on your performance, you need gear that works as hard as you do. For competitive swimmers and triathletes, a high-performance rashguard is key. These are typically form-fitting to reduce drag, helping you move with speed and efficiency. The durable fabric handles intense training and meets common competition rules, while also preventing chafing from equipment like a surfboard or rescue board. Check out our competitive swim collection for options designed to keep up with you.
For All-Day Comfort
Sometimes, you just want a shirt that feels good. For a casual swim or lounging by the pool, a relaxed-fit rashguard is your best bet. These are designed to feel more like your favorite t-shirt than a piece of high-tech gear. The looser cut allows for total freedom of movement, so you never feel restricted. It’s the perfect combination of comfort and function, giving you sun protection without the tight squeeze of a compression fit. You can find plenty of comfortable styles in our men's new arrivals.
For Versatility In and Out of the Water
The best rashguards are the ones you can wear anywhere. A versatile rashguard is perfect for days when your plans might change. Wear it for a morning swim, let it quick-dry, and then head to lunch without changing. These shirts are great for any outdoor activity, from a day on the lake to a hike near the coast. They pair just as easily with swim trunks as they do with shorts or jeans, making packing for a trip that much simpler. Explore our swimwear new arrivals to find a style that fits your life.
How to Find the Perfect Fit
A rashguard that fits poorly is more than just a fashion faux pas; it can chafe, ride up, or fill with water, completely distracting you from your activity. The goal is to find one that feels like a second skin, offering protection and comfort without getting in your way. Finding that perfect fit isn't about luck. It’s about taking a few simple steps to understand your measurements and what you need from your gear. With the right approach, you can confidently pick a rashguard that will perform as hard as you do, whether you're catching a wave or swimming laps.
Read the Sizing Chart Correctly
We’ve all been there. You’re a medium in one brand, but a large in another. Sizing can feel inconsistent across the board, which is why you should ignore the letter on the tag (S, M, L) and go straight to the brand’s sizing chart. Most brands provide detailed charts with specific measurements for the chest, waist, and hips. Before you start shopping for new rashguards, take a moment to find your measurements. This simple step is the most reliable way to find the right size for your body type and avoid the hassle of returns.
Match the Fit to Your Activity
How your rashguard should fit depends entirely on what you’ll be doing. Are you training for a triathlon or surfing? A snug, fitted rashguard is your best bet. This compression-style fit reduces drag in the water and stays put during intense movement, so it won't ride up. On the other hand, if your plans are more relaxed, like paddleboarding or hanging out at the beach, a relaxed-fit rashguard offers more breathing room and comfort. Think about your primary activity to decide which style will serve you best.
Take Your Measurements
To use a sizing chart effectively, you need accurate numbers. Grab a soft measuring tape and take your measurements with minimal clothing on for the best results. For your chest, measure around the fullest part, keeping the tape level under your arms. For your waist, measure around your natural waistline, which is usually the narrowest part of your torso. Finally, measure the fullest part of your hips. Jot these numbers down so you have them handy while browsing the latest men's new arrivals.
Avoid Common Sizing Mistakes
One of the biggest mistakes is assuming your size in one brand will translate to another. Always, always check the specific sizing chart for the rashguard you’re interested in, as measurements can vary quite a bit. Another common error is buying a size up for a "looser" fit. If you want a relaxed style, buy a rashguard designed with a relaxed cut. Sizing up in a fitted style will just leave you with a baggy garment that can fill with water and weigh you down. Taking a moment to double-check the chart will save you time and ensure you get a piece of gear you love.
What to Look For in a High-Quality Rashguard
When you're trying to find the right rashguard, a few key features separate the great from the just-okay. Paying attention to the details ensures you get a piece of gear that protects you, feels comfortable, and lasts for many seasons to come. Here’s what to keep an eye on.
Check the UPF Rating
A rashguard's main job is sun protection, which is measured by its UPF (Ultraviolet Protection Factor) rating. Always look for a rating of UPF 50+, which blocks about 98% of the sun's harmful rays. This is a must-have for long days in the water, as it means you can spend more time doing what you love without constantly reapplying sunscreen to covered areas. Many of our latest rashguard arrivals feature this essential level of protection, so you can stay safe under the sun.
Look for Flatlock Stitching
Comfort is key, and that’s where stitching makes a huge difference. High-quality rashguards use flatlock stitching, where the seams lie completely flat against the fabric. This design prevents the rubbing and chafing that can happen with traditional seams, especially during activities with a lot of movement. This small detail allows you to move freely and without irritation. For anyone in competitive swim, this feature is crucial for maintaining focus and comfort during long training sessions in the pool.
Prioritize Quick-Drying Fabric
The material of your rashguard impacts its performance in and out of the water. Look for fabrics made from a blend of polyester, nylon, and spandex, which are stretchy and designed to be quick-drying. A rashguard that holds water will feel heavy and cold. A quick-drying fabric wicks moisture away from your skin, helping you stay comfortable and regulate your body temperature. This is perfect for transitioning between the water and the shore. You can explore the latest fabric technologies in our men's new arrivals.
Invest in Durability
A good rashguard should handle saltwater, chlorine, sun, and sand. Durability comes down to the quality of the fabric and its construction. Look for materials that are resistant to fading and stretching, along with strong, reinforced seams. While a more durable rashguard might have a higher price tag, it's a smart investment that saves you money over time. It will maintain its shape and protective qualities, giving you reliable performance season after season. Investing in quality swim gear means you can count on it when you need it most.
How to Get the Best Value on Your Rashguard
Finding a great rashguard that fits your budget is easier than you think. Getting the best value isn’t just about finding the lowest price tag; it’s about investing in a quality piece of gear that protects you, feels comfortable, and holds up through countless sessions in the water. A little smart shopping can help you find a high-performance rashguard that you’ll love for seasons to come without overspending. Here are a few practical tips to help you get the most for your money.
Find Great Prices and a Wide Selection
To find the best value, start by looking at retailers that specialize in swimwear. A dedicated swim shop will offer a more curated and extensive selection than a general department store. This means you’ll have more choices when it comes to brands, fits, UPF ratings, and styles. Having a wide variety to choose from makes it much easier to find the perfect rashguard that meets your specific needs for performance and comfort. Check out the rashguard new arrivals to see a range of options from trusted brands all in one place.
Shop Seasonal Sales and Clearance
One of the easiest ways to save on high-quality gear is to keep an eye out for sales. Many retailers offer discounts at the end of a season or during major holidays. This is the perfect time to snag a premium rashguard at a fraction of its original price. If you don’t need the latest style, the Clearance Corner is another goldmine for incredible deals. I recommend signing up for your favorite swim shop’s email newsletter so you’re the first to know when a sale drops.
Know What to Expect at Different Price Points
Rashguard prices can vary quite a bit, and it’s helpful to understand what you’re getting at different levels. Generally, a higher price point reflects more advanced features, such as a higher UPF rating, more durable flatlock stitching, and premium, quick-drying fabrics. While a less expensive rashguard might be fine for occasional beach trips, a competitive swimmer or triathlete will benefit from investing in a higher-quality garment designed for performance. Consider how often you’ll wear it and what activities you’ll be doing to decide what price range makes sense for you.
Make a Smart Investment
Think of your rashguard as an investment in your comfort and skin safety. The best value comes from a product that lasts. A well-made rashguard constructed from durable materials like polyester and spandex will withstand chlorine, salt, and sun far better than a cheaply made alternative. This means you won’t have to replace it as often, saving you money over time. When you choose gear built for your sport, like pieces from a competitive swim collection, you’re paying for quality that performs when you need it most.
How to Care for Your Rashguard
You’ve found the perfect rashguard, and it’s serving you well in the water. To make sure it lasts for many seasons to come, a little bit of care goes a long way. Taking proper care of your rashguard isn't just about keeping it looking good; it's about preserving the technical features you bought it for, like its UPF sun protection and comfortable fit. Luckily, the process is simple. By following a few key steps for washing, drying, and storing, you can extend the life of your gear and ensure it performs at its best every time you wear it.
Wash It the Right Way
The first rule of rashguard care is to rinse it with cool, fresh water immediately after you get out of the pool or ocean. This simple step washes away damaging salt, chlorine, and sand before they have a chance to settle into the fabric. When it’s time for a proper wash, hand-washing in cold water with a mild detergent is your best option. One of the most common mistakes is using hot water, which can break down the delicate fibers like spandex and compromise the fabric’s elasticity. If you must use a machine, place the rashguard in a mesh laundry bag and run it on a gentle cycle with cold water. Always skip the fabric softener and bleach, and never put your rashguard in the dryer. The high heat will ruin the fit and reduce its UPF rating. Instead, lay it flat or hang it to air dry in a shady, well-ventilated spot.
Store It Properly
How you store your rashguard is just as important as how you wash it. Before you even think about putting it away, make sure it is one hundred percent dry. Storing it while even slightly damp can lead to mildew and unpleasant odors that are tough to get rid of. Once it’s completely dry, avoid folding it in a way that could cause creases or damage to the fabric. The best methods are to either roll it loosely or hang it on a wide, plastic hanger in your closet. Storing your swim gear in a cool, dry place away from direct sunlight will also prevent the colors from fading and protect the material from degrading, keeping it ready for your next adventure.
Know When It's Time for a New One
Even the best-cared-for rashguard won’t last forever. It’s important to recognize the signs that it’s time for a replacement to ensure you’re still getting the protection you need. Look for visible signs of wear like thinning fabric, pilling, or colors that have significantly faded. The most critical sign is a loss of elasticity. If your rashguard feels loose, stretched out, or no longer snaps back into shape, its UPF protection is likely compromised. Modern rashguards use advanced materials and compression technology to support muscles and reduce fatigue, so if yours is losing its form, you’re missing out on key performance benefits. When you spot these signs, it’s a good time to find your next favorite piece.

Frequently Asked Questions
Should my rashguard feel tight? The right fit really depends on what you're doing. For performance activities like competitive swimming or surfing, a snug, form-fitting rashguard is what you want. This tight fit reduces drag in the water and stays put, so it won't bunch up or get in your way. If you're planning a more relaxed day of paddleboarding or just hanging out by the water, a relaxed-fit rashguard will feel more like a comfortable t-shirt and give you more room to breathe.
Can I wear a rashguard instead of applying sunscreen? A rashguard with a UPF 50+ rating provides excellent sun protection for the skin it covers, and it won't wash off like sunscreen. However, it doesn't protect your exposed skin. You will still need to apply a good waterproof sunscreen to your face, neck, hands, and any other areas not covered by the rashguard to stay fully protected from the sun's rays.
What's the real difference between a rashguard and a regular swim shirt? While they might look similar, a rashguard is a piece of technical gear. It's made from specific synthetic blends like polyester and spandex that are lightweight, quick-drying, and stretchy. It's designed to fit snugly to reduce drag and prevent chafing with features like flatlock stitching. A typical swim shirt is often made of simpler materials and has a looser fit, making it better for casual wear but less effective for athletic performance.
Is it okay to wear my rashguard in a chlorinated pool? Yes, you can absolutely wear your rashguard in a pool. High-quality rashguards are built to withstand chlorine. The most important thing you can do to make it last is to rinse it with cool, fresh water as soon as you get out of the pool. This simple step washes away the chlorine before it can damage the fabric's fibers and compromise its stretch and UPF protection.
How do I know when it's time to replace my rashguard? Even with the best care, a rashguard will eventually wear out. The most obvious sign is when the fabric loses its elasticity and starts to feel loose or stretched out. This indicates that its protective qualities and performance fit are likely diminished. You should also look for visible thinning of the material, significant color fading, or seams that are starting to fray. Once you notice these signs, it's time to invest in a new one to ensure you're getting proper protection and comfort.
