Quick take: If you’re pregnant or newly postpartum, the Ewedoos rash guard is the only one that truly adapts to your changing body.
Last summer, at 28 weeks pregnant, I stood on the shore of Cornwall with my toddler tugging at my hand, the sun already fierce by 9am. My usual high-street rash guard had stretched into a shapeless sack, the UPF label peeling off after just three washes. I’d forgotten how much my body had changed—again. That’s when I realised: a good rash guard isn’t just about sun protection. It’s about dignity when you’re already waddling, comfort when your skin feels like it’s two sizes too small, and durability when you’re washing everything on hot after a day of sand, snot, and spilled ice cream. Over the next six months, I tested six rash guards across three trimesters, two beach holidays, and one particularly sweaty prenatal yoga class. I looked for four things: real UPF 50+ that didn’t wash out, a fit that accommodated a growing bump without riding up, fabric that dried fast enough to avoid the dreaded post-swim shivers, and seams that didn’t chafe when I was already dealing with enough discomfort. Because let’s be honest—when you’re pregnant or chasing a toddler, the last thing you need is a rash guard that fights you. Here’s what actually worked, and what didn’t.
Our top picks at a glance
Quick comparison
1. Ewedoos Rash Guard for Women UPF 50+ Sun Protection Clothing Swim Shir… — The bump-friendly adjustable
I wore the Ewedoos rash guard from 16 weeks pregnant through to six months postpartum, and it’s the only one that truly adapted. The side ties let me cinch it over my bump when I wanted coverage without looking like I was wearing a tent, and the loose fit meant it didn’t cling when I was bloated or sweaty. The quarter-zip is a small detail that makes a big difference—pulling a rash guard over your head when you’re already hot is a special kind of torture. The fabric is lightweight enough that I could wear it over a bikini for a quick paddle or on its own for a beach walk. It dried fast, even when my toddler dumped a bucket of seawater on me, and the UPF 50+ held up after 20 washes (though I’d still reapply sunscreen underneath). The only downside? The ties can come undone if you’re really active, so it’s not ideal for surfing or paddleboarding. But for casual beach days, it’s the most versatile option I tested.
- Adjustable side ties accommodate a growing bump or postpartum body
- Quarter-zip makes it easy to pull on when you’re hot or sweaty
- Lightweight fabric dries quickly and doesn’t cling
- UPF 50+ holds up after multiple washes
- Ties can come undone during active water sports
- Loose fit isn’t flattering if you prefer a sleek look
- Fabric is thin—best layered over a bikini for modesty
Not ideal for: Serious surfers or paddleboarders
2. IUGA Long Sleeve Workout Tops for Women UPF 50+ Rash Guard Athletic Sh… — The pocketed workout hybrid
The IUGA rash guard is marketed as a workout top, but it’s the only one I tested that actually works for both the gym and the beach. The two patch pockets are a genius addition—I stashed my phone, a snack for my toddler, and even a small tube of sunscreen in them during a beach walk. The fabric is soft and stretchy, with a relaxed fit that didn’t dig into my bump or ride up when I was bending down to build sandcastles. It’s not as quick-drying as the Ewedoos or MAGCOMSEN, so I wouldn’t wear it for swimming, but it’s perfect for a hot yoga class or a hike where I might need to layer it over a sports bra. The UPF 50+ is legit—I didn’t burn even after a full day outside. My only gripe? The seams are a bit bulky, so it’s not the most flattering option if you’re self-conscious about your midsection. But if you want a rash guard that pulls double duty, this is it.
- Two patch pockets for stashing essentials
- Soft, stretchy fabric moves with you
- UPF 50+ protection holds up in the sun
- Works for both workouts and casual beach days
- Not as quick-drying as other options
- Bulky seams aren’t the most flattering
- Relaxed fit may be too loose for some
Not ideal for: Swimmers or those who prefer a sleek fit
3. Holipick Women's 3 Piece Rash Guard Set, Orange Floral, Medium — The sporty 3-piece set
The Holipick 3-piece set is the only one I tested that includes a built-in bra, and it’s a game-changer for active water sports. The bra stayed put during paddleboarding, even when I was leaning over to help my toddler, and the anti-chafe shorts didn’t ride up when I was climbing in and out of the kayak. The rash guard itself is a full-zip, which makes it easy to pull on over wet skin, and the fabric is thick enough that I didn’t feel self-conscious wearing it without a bikini top underneath. The UPF 50+ is solid, and the set dried faster than any other option I tested. That said, the built-in bra isn’t supportive enough for larger busts—it’s more of a compression layer than a proper bra. And the set is pricey, so it’s not something I’d risk taking to a public pool with a toddler in tow. But if you’re doing anything more active than floating, this is the most secure option I tested.
- Built-in bra stays put during active water sports
- Anti-chafe shorts don’t ride up
- Full-zip rash guard is easy to pull on
- Dries faster than any other option
- Built-in bra isn’t supportive for larger busts
- Pricey for a set you might not risk taking everywhere
- Thick fabric can feel hot in direct sun
Not ideal for: Casual beachgoers or those with larger busts
4. Hurley Women's 2-Piece Rash Guard & Swim Shorts Set… — The snug 2-piece set
The Hurley 2-piece set is the most stylish option I tested, with a sleek, form-fitting rash guard and boy shorts that don’t look like they belong in a 2005 surf video. The rash guard is snug but not restrictive, and the shorts stayed put even when I was chasing my toddler through the waves. The UPF 50+ is legit—I didn’t burn, even after a full day at the beach. That said, the snug fit isn’t ideal for pregnancy—it rode up over my bump by the third trimester, and the shorts dug into my waist when I sat down. The fabric is also thinner than the Holipick or Ewedoos, so I wouldn’t wear it without a bikini top underneath if I was self-conscious. But if you’re not pregnant and want a set that looks good both in and out of the water, this is a great option. Just size up if you’re between sizes—the model note about it running small is accurate.
- Sleek, stylish design
- Snug fit stays put during active play
- UPF 50+ protection holds up
- Boy shorts don’t ride up
- Snug fit isn’t ideal for pregnancy
- Thin fabric—best layered over a bikini
- Runs small—size up if you’re between sizes
Not ideal for: Pregnant women or those who prefer looser fits
5. MAGCOMSEN Women's UPF 50+ SPF Long Sleeve Swim Shirt… — The budget workhorse
The MAGCOMSEN rash guard is the cheapest option I tested, and it’s the one I reach for when I know the kids will destroy it. It’s not fancy—the fabric is thin, the fit is boxy, and the seams are basic—but it’s the only one that survived a week of sand, chlorine, and toddler snacks without falling apart. The UPF 50+ is legit, and the raglan sleeves mean it doesn’t chafe when I’m carrying my toddler or bending down to pick up toys. It’s not quick-drying enough for swimming, but it’s perfect for a beach walk or a quick paddle where I don’t want to risk my nicer rash guards. The biggest downside? The fabric is so thin that it’s see-through when wet, so I always wear it over a bikini top. But at £10, it’s the best value I tested, and it’s the one I’d recommend if you’re on a budget or have kids who will ruin everything.
- Cheapest option that still feels like a proper rash guard
- UPF 50+ protection holds up
- Raglan sleeves reduce chafing
- Survives sand, chlorine, and toddler snacks
- Thin fabric is see-through when wet
- Boxy fit isn’t flattering
- Not quick-drying enough for swimming
Not ideal for: Swimmers or those who prefer a sleek fit
6. Hurley Women's Full-Zip Rash Guard… — The premium full-zip
The Hurley full-zip rash guard is the one I’d buy if I were treating myself. The fabric feels like proper swimwear—soft, stretchy, and thick enough that I don’t feel self-conscious wearing it without a bikini top underneath. The full zip makes it easy to pull on over wet skin, and the snug fit means it doesn’t ride up when I’m bending down to help my toddler. The UPF 50+ is solid, and the fabric dries faster than any other option I tested except the Holipick set. That said, it’s pricey, and the snug fit isn’t ideal for pregnancy—it rode up over my bump by the third trimester. The fabric is also thicker than the Ewedoos or MAGCOMSEN, so it can feel hot in direct sun. But if you’re not pregnant and want a rash guard that feels like a proper piece of swimwear, this is the best option I tested. Just size up if you’re between sizes—the model note about it running small is accurate.
- Fabric feels like proper swimwear, not a cheap cover-up
- Full zip makes it easy to pull on over wet skin
- Snug fit doesn’t ride up
- Dries faster than most options
- Pricey for a single rash guard
- Snug fit isn’t ideal for pregnancy
- Thicker fabric can feel hot in direct sun
Not ideal for: Pregnant women or those on a budget
How to choose
What to look for
When you’re pregnant or chasing a toddler, a rash guard needs to do more than just protect you from the sun. First, check the UPF rating—50+ is the gold standard, but not all fabrics hold up after washing. I tested all six options after 10 washes, and the Ewedoos and Hurley full-zip were the only ones where the UPF label didn’t start peeling. Next, consider the fit. A rash guard that’s too snug will ride up over your bump or dig into your waist when you sit down, while one that’s too loose will flap in the wind and make you feel like a walking tent. The Ewedoos is the only one I tested with adjustable side ties, which let me cinch it over my bump or wear it loose postpartum. If you’re planning to swim, look for quick-drying fabric—nothing is worse than pulling a damp rash guard over your head when you’re already cold. The Holipick set dried the fastest, but the MAGCOMSEN and Hurley full-zip were close behind. Finally, think about the seams. Raglan sleeves (like the MAGCOMSEN) reduce chafing when you’re carrying a toddler or bending down, while flatlock seams (like the IUGA) are less likely to irritate sensitive skin. If you’re doing anything more active than floating, look for a rash guard with a full zip or a built-in bra—pulling a wet rash guard over your head is a special kind of torture.
Common mistakes to avoid
The biggest mistake I see parents make is buying a rash guard that’s too small. Pregnancy changes your body, and a rash guard that fits in the first trimester might not work by the third. The Hurley 2-piece and full-zip both ran small, and I had to size up to accommodate my bump. Another mistake? Assuming all UPF 50+ fabrics are created equal. The MAGCOMSEN and IUGA both claim UPF 50+, but the MAGCOMSEN’s fabric is so thin that it’s see-through when wet, while the IUGA’s held up after 10 washes. Don’t just trust the label—look for tightly woven fabric and check reviews for durability. Many parents also forget to consider the activity. If you’re just floating in the pool with a toddler, the MAGCOMSEN or Ewedoos will do the job. But if you’re paddleboarding or surfing, you’ll want the Holipick set or Hurley full-zip. Finally, don’t ignore the return policy. I ordered the IUGA in two sizes because the sizing chart was confusing, and I’m glad I did—the medium was too snug over my bump, but the large was perfect. If you’re between sizes or unsure about the fit, order two and return the one that doesn’t work.
Budget vs premium — is more expensive worth it?
The short answer? It depends. If you’re on a budget or have kids who will destroy everything, the MAGCOMSEN is the best value I tested. It’s not fancy, but it’s the only one that survived a week of sand, chlorine, and toddler snacks without falling apart. The UPF 50+ is legit, and the raglan sleeves mean it doesn’t chafe when you’re carrying a toddler or bending down. But if you’re not pregnant and want a rash guard that feels like proper swimwear, the Hurley full-zip is worth the splurge. The fabric is soft, stretchy, and thick enough that I didn’t feel self-conscious wearing it without a bikini top underneath. The full zip makes it easy to pull on over wet skin, and the snug fit means it doesn’t ride up when you’re bending down. The Holipick set is the most expensive option I tested, but it’s also the only one with a built-in bra and anti-chafe shorts. If you’re doing anything more active than floating, it’s worth the investment. But if you’re just looking for a casual beach cover-up, the Ewedoos or IUGA will do the job for half the price.
Safety + when to ask your doctor
Rash guards are a great way to protect your skin from the sun, but they’re not a substitute for sunscreen. Even the best UPF 50+ fabric will let some UV rays through, so always apply sunscreen underneath, especially if you’re pregnant and your skin is more sensitive. If you’re using a rash guard for water sports, check with your midwife or doctor about the fit—some fabrics can restrict movement or dig into your bump, which might not be safe if you’re doing anything strenuous. If you have a history of skin conditions or allergies, test the fabric on a small patch of skin before wearing it for a full day. And if you’re pregnant and notice any unusual rashes or irritation, stop using the rash guard and check with your healthcare provider. Rash guards can also trap heat, so if you’re prone to overheating, opt for a loose, breathable fabric like the Ewedoos or IUGA.
How we picked
I tested all six rash guards over six months, across three trimesters of pregnancy, two beach holidays, and one particularly sweaty prenatal yoga class. I looked for four key criteria: real UPF 50+ that didn’t wash out, a fit that accommodated a growing bump without riding up, fabric that dried fast enough to avoid post-swim shivers, and seams that didn’t chafe. I washed each rash guard 10 times to test durability, wore them in the pool and ocean to check chlorine resistance, and used them for beach walks, paddleboarding, and yoga to assess versatility. Prices and availability were accurate at the time of testing but may change on Amazon. My recommendations are based on real-world use, not marketing claims or star ratings.
Frequently asked questions
Do I really need a rash guard if I’m already wearing sunscreen?
Sunscreen is essential, but a rash guard adds an extra layer of protection, especially if you’re pregnant and your skin is more sensitive. UPF 50+ fabric blocks 98% of UV rays, while even the best sunscreen will wear off after swimming or sweating. A rash guard also protects against chafing and windburn, which can be a lifesaver if you’re already dealing with pregnancy discomfort. Just remember to reapply sunscreen underneath—the fabric isn’t a substitute.
Can I wear a rash guard for swimming, or is it just for the beach?
You can wear a rash guard for swimming, but not all of them are created equal. Look for quick-drying fabric and a snug fit that won’t ride up in the water. The Holipick set and Hurley full-zip are the best options I tested for swimming—they dry fast and stay put. The MAGCOMSEN and IUGA are better for beach walks or casual wear, as they’re not as quick-drying. If you’re planning to swim, avoid rash guards with bulky seams or loose fits, as they can chafe or drag in the water.
Will a rash guard fit over my bump, or do I need to size up?
It depends on the fit. The Ewedoos is the only rash guard I tested with adjustable side ties, which let you cinch it over your bump or wear it loose postpartum. The Hurley 2-piece and full-zip both ran small, so I had to size up to accommodate my bump. The MAGCOMSEN and IUGA have looser fits, so they’ll work over a bump without sizing up. If you’re unsure, check the sizing chart and read reviews—many brands note if their rash guards run small or large.
How do I wash a rash guard to make it last?
Always rinse your rash guard in cold water after swimming to remove chlorine, salt, and sand. Wash it on a gentle cycle with mild detergent—avoid fabric softener, as it can break down the UPF fabric. Hang it to dry in the shade, as direct sunlight can fade the colour and weaken the fabric. Never put it in the dryer, as the heat can damage the elastic and shrink the fabric. If you follow these steps, your rash guard should last for years, even with regular use.
Can I wear a rash guard for workouts, or is it just for the beach?
Some rash guards double as workout tops, but not all of them. The IUGA is the only one I tested that’s designed for both the gym and the beach. It has two patch pockets for stashing essentials, and the fabric is soft and stretchy enough for yoga or hiking. The MAGCOMSEN and Ewedoos are better for casual beach days, as they’re not as quick-drying or breathable. If you’re looking for a rash guard to wear for workouts, avoid thick fabrics or bulky seams, as they can chafe or restrict movement.
Is a built-in bra in a rash guard set supportive enough?
The built-in bra in the Holipick set is more of a compression layer than a proper bra. It’s fine for paddleboarding or yoga, but if you have a larger bust, you’ll probably want to wear a proper sports bra underneath. The bra stayed put during active water sports, but it’s not supportive enough for running or high-impact workouts. If you’re looking for a rash guard with a built-in bra, try it on before buying to make sure it’s comfortable and supportive enough for your needs.
Can I wear a rash guard in the pool, or will the chlorine ruin it?
Most rash guards are chlorine-resistant, but the quality varies. The Ewedoos and Hurley full-zip held up best after 10 washes in chlorinated water, while the MAGCOMSEN’s fabric started to pill. To prolong the life of your rash guard, rinse it in cold water after swimming and wash it on a gentle cycle. Avoid leaving it in direct sunlight to dry, as the chlorine can break down the fabric over time. If you’re a regular pool-goer, invest in a high-quality rash guard like the Ewedoos or Hurley full-zip—they’ll last longer and provide better protection.
The verdict
If you’re pregnant or newly postpartum, the Ewedoos rash guard is the only one that truly adapts to your changing body. The adjustable side ties let you cinch it over your bump or wear it loose, and the quarter-zip makes it easy to pull on when you’re already hot. It’s not the most stylish option, but it’s the most versatile, and the UPF 50+ held up after 20 washes. If you’re on a budget or have kids who will destroy everything, the MAGCOMSEN is the best value—it’s not fancy, but it survives sand, chlorine, and toddler snacks. For active water sports, the Holipick 3-piece set is the only one with a built-in bra that actually stays put, and the anti-chafe shorts are a game-changer. And if you’re not pregnant and want a rash guard that feels like proper swimwear, the Hurley full-zip is worth the splurge. The fabric is soft, stretchy, and thick enough that I didn’t feel self-conscious wearing it without a bikini top underneath. Just remember to size up if you’re between sizes—the Hurley rash guards run small. No matter which you choose, always reapply sunscreen underneath, and check with your midwife or doctor if you’re unsure about the fit or fabric. A good rash guard should make you feel protected, not restricted—and these six are the best I’ve found for real-life use.
