Our Picks at a Glance
How To Choose The Best Women’s UV Shirts for Swimming
You want a swim shirt that blocks the sun without sacrificing comfort or style. Every option here blocks harmful rays, so your real choice is fit, closure style, and if you want a built-in bra. Here’s how to pick the best women’s UV shirt for your swimming routine.
UPF rating is the non-negotiable
UPF stands for Ultraviolet Protection Factor. A UPF 50+ rating means the fabric blocks roughly 49 out of 50 parts of the sun’s UV radiation. Every shirt on this list meets that standard, so you can focus on fit and feel instead of coverage.
Fit runs small — plan ahead
The most common complaint across every product here is sizing. Several buyers report they needed to order one or even two sizes up from their normal dress size. If you are between sizes, size up. A snug rash guard is fine, but one that digs in at the shoulders or sleeves will ruin your beach day.
Closure style changes how it feels
Pull-on shirts are simple and lie flat, but a full-zip or half-zip front makes the shirt much easier to get on and off when wet. The full-zip versions also let you adjust ventilation and coverage as the day heats up. Thumb holes on long-sleeve styles keep the backs of your hands sunburn-free.

In-Depth Reviews
1. BesserBay Women’s Rash Guard UPF 50+ Short Sleeve
Our pick — over 4.5★ from 750+ verified ratings; the strongest balance of quality and price.
The BesserBay Short Sleeve flatters smaller frames and delivers UPF 50+ protection (a fabric rating that blocks 98% of UV rays) so you can stay out longer without worrying about sunburn.
Fit is the thing that wins people over here — the top praised aspect across buyer feedback, and the reason this shirt earns the top spot. Smaller-built women especially note it’s cut for them, unlike many tops “cut for the larger crowd” that hang loose and baggy. The material is described as “super for swimming,” though it will cling to your body once you step out of the water, so plan to wear a sports bra underneath.
This is a short-sleeve, pull-on shirt, so it’s simpler and cooler than the long-sleeve options. The colors are a recurring highlight — “gorgeous colors and not see through at all” — and owners mention real, effective sun protection, with one crediting it for saving her back from sunburn. What wins people over is the combination of a flattering silhouette and dependable UPF 50+ coverage.
Here’s the honest catch: sizing runs small, and customers note the shirt lasts about one summer of regular use. One owner put it plainly: “I had to size up and I only get one summer out of them.” So you get a great-fitting, protective top at a friendly price, but don’t expect it to survive multiple seasons.
What owners love
- Flattering fit that works for smaller frames
- Real sun protection — reviewers point out no burns
- Colors are “gorgeous” and not see-through
The trade-offs
- Runs small — size up, possibly two sizes
- Longevity is about one summer of regular wear
- Clingy when wet — wear a sports bra under it
Grab it if: you want a short-sleeve, pull-on shirt that fits well and looks great for beach days or pool time.
Think twice if: you need a shirt that survives multiple seasons — this one is a one-summer top.
2. Speedo Women’s UV Swim Shirt Long Sleeve Rashguard
A pilling-resistant long-sleeve built for chlorine, salt water, and serious movement.
Speedo cut this from its Enduraflex fabric specifically for higher chlorine resistance and shape retention, so it holds up where cotton blends would stretch out and pill. It’s a color-block long-sleeve top with a body-skimming fit that shoppers say flatters broad shoulders and dries fast, making it a strong pick for lap swimming and paddleboarding.
Sun protection is the headline: buyers report it “definitely blocks out the sun” and they “love that it allows me to stay in the water longer.” One 5’8″ swimmer at 125 lbs wore a size S for two weeks without a single burn, proof the UPF 50+ fabric works. The fabric feels silky and light, with enough room for full body and arm movement.
The recurring gripe is sizing inconsistency — the medium runs large for some, so check measurements rather than guessing. Sleeves also run long, reaching to the wrist bone even on a shorter frame. That’s a plus if you want extra hand coverage, but worth knowing before you order.
Built for the water: chlorine-resistant Enduraflex fabric that holds its shape and blocks the sun, so you stay out longer without burning.
Know before you buy: sleeves run long and it’s a pull-on, so be ready to size-check carefully.
Choose this for: active water days — laps, surf, or paddleboarding — where fabric durability actually matters.
skip it if: you want a short sleeve or an easy zip-front closure.
3. Hurley Women’s Full-Zip Rash Guard, Long Sleeve UPF 50+
The full-zip long sleeve that layers easily and keeps you burn-free through a week of Hawaii sun.
The defining spec here is the full-zip front — it makes on-and-off easy when wet, and buyers call out the smooth zipper as a favorite detail. Form-fitting but flexible, it stays put while swimming, and the flat-locked seams mean no chafing even on long active days. It’s the shirt people reach for across beach, snorkeling, and hiking trips.
Sun protection is outstanding: one owner took it to Hawaii and reported “zero sunburn in covered areas” across a week of beach, snorkeling, and hiking. The quick-dry fabric and moisture-wicking material keep you comfortable in and out of the water, and the lightweight stretch moves with you. Several owners mention it survived heavy use without fading or stretching.
It’s true to size for most, though a few find it runs a little small around the shoulders and arms — buyers with wider shoulders and bigger arms still found a great fit. Compared to the BesserBay short sleeve, this one costs a bit more but brings the zip convenience and long-sleeve coverage.
The easy layer: full-zip front with UPF 50+ and quick-dry fabric, fit for everything from swimming to hiking.
The honest note: it runs snug for some; if you’re between sizes, go up.
Reach for this if: you want a zip-front long sleeve that takes you from surf to trail without a second thought.
Look elsewhere if: you prefer a loose, oversized fit — this one is form-fitting by design.
4. Santiny Women’s UPF50+ Rash Guard with Thumb Holes
The adjustable long sleeve with thumb holes built for kayaking, hiking, and yard work.
Thumb holes are the standout feature — they keep the backs of your hands sunburn-free and improve grip, which is why this one keeps showing up in kayaking and paddleboarding conversations. The cinch sides let you tighten the fit for a custom, flattering silhouette, an adjustable detail most rash guards simply don’t offer. It’s the kind of shirt that works for water sports, hiking, and even yard work.
Protection is proven: one reviewer wrote, “I spent three days in the Caribbean sun wearing this swim top and did not get burned at all.” The soft, stretchy, breathable fabric keeps you cool on hot days, and customers note it survives chlorine, salt water, and repeated washes without fading or stretching. The thickness earns praise too — substantial enough to feel durable without being hot.
The length gets mixed feedback: true to size for many, but the sleeves run long and the torso runs small for larger sizes. One buyer wishes the sleeves were shorter, while another values the extra coverage. If you want full hand protection from sun and chafe, this is a strong mid-range pick — the fit at the high end is what you need to check.
Why it stands out
- Thumb holes protect your hands and improve grip
- Cinch sides give an adjustable, flattering fit
- Holds up through washes — no fade, no stretch
Check the fit
- Sleeves run long for shorter arms
- Runs small in the body for larger sizes
Best for: active outdoorsy days where hand protection and a custom fit matter more than a zip.
Not ideal if: you have a shorter torso and want a relaxed, non-adjusted fit.
5. WOWENY Women’s Rash Guard UPF 50+ with Thumb Holes
The half-zip long sleeve that is cute enough to wear as a regular top.
Let’s get the headline out of the way: “Adorable enough to wear as a regular top too!” The prints are the hook — floral, easy-match colors, and patterns that reviewers point out are “super cute” and flattering. Fit is the most-praised aspect, with owners loving the length and the way it skims the figure rather than hanging boxy.
The thumb holes and zipper cover are functional details that earn frequent mentions. Shoppers say the stretchy fabric washes well without wrinkles or sagging, and the smooth zipper holds up. It’s a shirt people buy in multiple colors — one owner is on her second purchase and uses it for both swimming and scrubs at work.
Here’s the honest trade-off: the fabric is not breathable at all, which is likely intentional for a swim top but makes it uncomfortable for hot outdoor sports. One owner tested it on an 80°F hike and found it stifling. Sizing also runs small for some — one buyer had to send hers back even though she’d ordered her usual size.
The wins
- Cute prints that work as a regular top too
- Thumb holes protect the backs of your hands
- Washes well with no wrinkles or sagging
The limits
- Fabric is not breathable for hot outdoor sports
- Runs small for some — check the size chart
Pick this for: style-first swimmers who want a flattering print that does double duty as a regular top.
pass on it if: you plan to hike or run in it on hot days — this fabric traps heat.
6. Halcurt Plus Size Long Sleeve Rash Guard with Built-in Bra
A loose, drape-friendly long sleeve in 1X-4X with a sewn-in bra that does the job.
The sewn-in bra is the reason to pick this one — no fiddling with separate pieces, and owners call it “an added bonus” and “great.” The loose fit is deliberate: the drape hides flaws and hangs like a regular shirt, which is exactly what many buyers want. Raglan sleeves (cut in one piece from collar to underarm) give good arm mobility, whether you’re swimming or doing yard work in it.
Sun protection is reliable — “did its job protecting my arms from sunburn.” Buyers report the black color doesn’t fade, the fit is flattering, and the quality holds up through pool use and washing. It’s described as quick-drying and easy to pull on, with a generously cut fit; some owners mention they could easily have gone down a size or two.
The catch: this is a pull-on top, so there’s no zip for adjustability or easy removal when wet. And it runs large — the “loose fit” is real, so if you prefer a skimming silhouette, you’ll want to size down. One owner noted the dolphin decal peeled off after a day in salt water, a minor cosmetic issue on an otherwise solid shirt.
Comfort-first coverage: loose drape, sewn-in bra, and UPF 50+ in sizes 1X-4X — pure function for swimming and everyday wear.
The flip side: runs generously large and has no zipper, so factor that into your size choice.
Grab it if: you want plus-size coverage with a built-in bra and a relaxed, forgiving fit.
Look elsewhere if: you prefer a snug, zip-front shirt — this one is loose and pull-on by design.
7. Halcurt Women’s 2-Piece Rash Guard with Boyleg Swimsuit
This 2-piece set pairs a top with boyleg shorts featuring a 5-inch inseam and a built-in bra for modest, low-maintenance coverage.
Coverage is the whole point of this set. The boyleg shorts with a 5-inch inseam cover your thighs and prevent chafing, while the built-in bra and high neckline offer support without extra pieces. Owners describe it as “one of the best bathing suits I’ve ever bought” — the fit works especially well for water aerobics classes, where staying put matters.
The comfort story is strong: fabric that isn’t too thick, shorts that don’t ride up, and material that dries quickly after swimming. Fit is the most-praised aspect, with buyers noting it’s true to size — particularly in small — and flattering even for those who are self-conscious about their midsection. “Covers problem areas, flattens stomach” is a recurring theme in the feedback.
The honest limitation: the built-in bra has little support for fuller busts. A 36D buyer found the cups too small and the top lacking support, while a B-cup found it ideal. The shorts also run slightly large for smaller hip sizes. If you’re larger-chested, this set fits best for a B-cup range.
What works
- 5-inch inseam shorts prevent thigh chafing
- Built-in bra with high neckline for modest coverage
- Dries quickly and doesn’t ride up in the water
Who it’s not for
- Limited support for fuller busts (36D+)
- Shorts run large for smaller hip sizes
Choose this for: modest, all-in-one coverage for water aerobics, pool days, or home workouts — chest sizes B to C.
Pass it by if: you’re a D-cup or larger and need real bust support from the built-in bra.
8. ALLTOKE Full Body Rash Guard with Built-in Bra
The one-piece full-zip that covers you from neck to feet for sun, jellyfish, and cooler waters.
This is the maximum-coverage option — a one-piece long-sleeve, long-pants suit built from 82% nylon and 18% spandex, with a built-in bra. It covers everything, which is exactly why buyers pick it for swimming in “cooler, murky ocean” where sun, jellyfish, and chill are all concerns. The full zip makes it easy to get on and off by yourself, and it dries quickly.
Fit is the most-praised aspect, with owners noting it doesn’t ride up even during intense pool workouts and swim lessons. The stretchy fabric clings in a comfortable way, and the zipper is manageable solo — “zipper was easy to do by yourself” is a recurring line. For sun protection, it’s the complete package: “exactly what I wanted to stay covered from the sun with bikini underneath.”
The trade-off is the built-in bra — it’s snug and offers limited support for a D-DDD+ bust. One hourglass owner at 47″ bust found the XL had only a little give and needed to follow the size chart carefully. It’s also the most coverage you can get, which means it’s the warmest option in hot, still air.
Maximum shield: neck-to-ankle UPF 50+ coverage in a stretchy 82/18 nylon-spandex one-piece that dries fast.
Consider first: the built-in bra runs snug for larger busts — size up if you’re D-cup or beyond.
Get it if: you want complete coverage for ocean swims, diving, or snorkeling where sun and jellyfish are real concerns.
it’s not for you if: you have a larger bust and need serious bra support — this one runs snug up top.
9. Daci 3-Piece Rash Guard Set with 3″ Shorts
A complete three-piece set — long sleeve, high-rise shorts, and built-in bra — that outfits you entirely.
Here’s everything in one package: a long-sleeve top, high-rise 3-inch shorts with ample booty coverage, and a built-in bra with removable pads. The UPF 50+ fabric blocks 99% of UVA/UVB rays, and buyers confirm it works — “SPF 50 effective — no tan/burn” after a week snorkeling in Hawaii. It’s a modest-but-cute combo that covers the tummy while still feeling stylish.
Fit is the most-praised aspect by a wide margin, and feedback is remarkably consistent across body types: a 5’8″ 150-lb owner found it fits well, a 5’10” 148-lb 34DDD owner says the medium fits perfectly, and a 5’7″ 160-lb buyer agrees. The adjustable straps help with chest support, the zipper is quality, and the long sleeve is easy to remove. It survives machine delicate washing and drying.
The short sleeves and shorts are a complete system, but that’s also the limitation — you can’t mix sizes between top and bottom. One reviewer noted the bottom ran too large for her size 11/12 while the top fit fine. And buyers wish it had pockets, which it doesn’t.
The package deal
- Long sleeve + high-rise shorts + built-in bra in one set
- Fits well across a range of body types
- Effective sun protection — no tan or burn reported
Know the limits
- Can’t mix sizes between top and bottom
- No pockets on the shorts
Best for: the budget-savvy buyer who wants one complete, coordinated outfit without buying pieces separately.
Not for: anyone who needs different sizes on top versus bottom — this set is one size for all.
Understanding the Specs
UPF 50+ vs. SPF
UPF (Ultraviolet Protection Factor) measures how much UV radiation a fabric blocks. UPF 50+ is the highest rating and blocks over 98% of UVA and UVB rays — the gold standard for swim shirts. SPF is a sunscreen measure, not a fabric one. Every shirt on this list carries UPF 50+, so you can trust the sun protection and focus on fit and features instead.
Fabric: Nylon-Spandex vs. Polyester
Nylon-spandex blends (like the 82% nylon / 18% spandex in the ALLTOKE suit) give a stretchy, body-skimming fit with good chlorine resistance. Polyester blends tend to be lighter and quicker-drying but can be less breathable — remember the WOWENY buyer who found the fabric not breathable at all. Consider what you’ll be doing: laps and chlorine favor nylon-spandex; hot, humid lounging favors something lighter.
