9 best long-sleeve swimsuits to wear year-round, reviewed by Glamour editors
If Kim K and Eva Longoria say we're wearing long-sleeve swimsuits, we're wearing long-sleeve one-piece swimsuits. Yep, our forever fashion idols opted for slightly more modest poolside attire last summer, and it's a trend we're keen to keep going. Why? Because sunburn is not on the agenda for 2026.

Thankfully, high street and luxury swimwear brands got the brief too – from fashion-forward Free People to Olympian-approved Speedo, most now stock long-sleeve swimwear options, some even offering added UV protection and aesthetic protection from chafing.

“The long-sleeve swimsuit has well and truly broken out of its ‘surf-only’ bubble,” says Joanna Bury, Finisterre's Senior Product Designer for Swimwear. “While it’s still the gold standard for athletes, it has evolved into a versatile essential for just about any activity, whether you’re in the water or out.
"Beyond the sporty aesthetic, these suits are practical powerhouses. Acting as a durable rash guard, they shield your skin from surfboard wax, rough sand, or the occasional jellyfish sting.”
Sold? Sure. Now onto which are worth your buck. As you know, Glamour's team of shopping editors rarely recommend products they haven't tested themselves — hence why I've spent the last month reviewing a host of long-sleeve swimsuits, including quick-drying crop tops, wetsuit-style swim tops and chic one-piece swimsuits to see which are best suited to open water swimming, surfing, paddleboarding, and lounging poolside.
So, read on to discover what I've deemed to be the best long-sleeve swimsuits of 2026, as well as answers from industry experts (swimwear designers and the like) to common swimwear FAQs. And, for those seeking the best tummy-control swimsuits and maternity swimwear, we've got those rounded up, too.

Ahead, the long-sleeve swimsuits Glamour editors will be wearing all summer long:
Gigi C Riley One-Piece Surf Suit
If it's good enough for Eva Longoria, it's good enough for us. This compressive long-sleeve suit features stylish geometric cut-out details and a front zipper for easy access. It's worth noting that fit-wise, it runs rather snug — and while some might prefer a sculpted look, I suggest sizing up if you'd prefer a more relaxed feel. Previous reviews on the site state that, despite delivering interesting tan lines, the suit did keep them warm while wild swimming, and was quick to dry once out.
- Available sizes: XS (UK 4-6) — XL (16-18).
- Available lengths: N/A.
- Material: 84% polyester, 16% spandex.
- Colours: 2.

Not only is this Boden swimsuit available in every size from a UK 4 to 22, but it also comes in three lengths (petite, regular and long), making it the most size-inclusive suit in this edit. In terms of fit, I took my usual size (12 Regular) and can confirm that I felt sculpted but not at all squeezed. I also appreciated the subtle V-neck, which ruled out any neck irritation while swimming. Available in a host of fun prints and colour combinations, and coming in at under £90, I'd say this ticks every box. In fact, if you happen to be in the Maldives next month, you might just see me wearing this to avoid the powerful midday sun.
- Available sizes: UK 4 — 22.
- Available lengths: Petite, Regular or Long.
- Material: 80% polyamide, 20% elastane.
- Colours: 5.

Kaia 2mm Yulex Long Sleeve Top
While I sometimes crave the added coverage a one-piece swimsuit offers, I hate how difficult it can be to go for a wee — and in a long-sleeve swimsuit, it's only harder. Thankfully, Finisterre has designed a top that can be paired with the matching shorts or any pair of bikini bottoms you already have in your rotation. Even better news: this one's crafted from Yulex rubber, sourced from Hevea trees for a more natural wetsuit alternative, plus it is transported only by land and sea (no air freight), in a bid to be more sustainable. And, with the option to rent, rather than buy, the brand attempts to limit clothing waste and unnecessary online returns, too.
In terms of its effectiveness as a swim layer, it's been designed with a 2mm thickness to help keep you warm. My only complaint? This one's hand wash only, meaning a little extra effort.
- Available sizes: UK 6 — 22.
- Available lengths: N/A.
- Material: 85% Yulex natural rubber, 15% synthetic rubber.
- Colours: 2.
Goodmove Scuba Padded Long Sleeve Swimsuit
Like most women in their 30s, Marks & Spencer's is my go-to for good quality cotton underwear and affordable swimwear. But never had I considered it might also options suitable for wild swimming. Coming in at under £50, I didn't have huge hopes, considering swimsuits in this category usually start at £80 and up. However, I was pleasantly surprised. Crafted from chlorine-resistant fabric and cut true-to-size, I felt sculpted and supported — plus, it was easy to get in and out of, thanks to that lengthy front zip. While I'm still yet to test how warm it'll keep me — see me wearing this to my local plunge pool later this month — a quick dip confirmed this to be quick-drying and not-at-all restrictive. My only constructive pointer? More design options, please!
- Available sizes: UK 6 — 24.
- Available lengths: N/A.
- Material: 80% polyamide, 20% elastane.
- Colours: 1.

I will wax lyrical about Hunza G's OG swimsuit at any opportunity, the iconic crinkle material working to flatter all shapes and sizes. But for brand fans who crave a little more coverage, it's delivered a long-sleeve option, better known as Tyra.
Most worthy of note? The fact that the material has a UPF rating of 50+ means it effectively blocks 98% of the sun’s rays. But it's also 74% recycled, giving it eco-credentials too. Comfort-wise, I had no complaints; the ultra-fine Italian fabric felt both soft and flexible. And that contrast piping? A classic design feature I love.
- Available sizes: XS (UK 6-8) — XL (14-16).
- Available lengths: N/A.
- Material: 74% recycled polyamide, 26% elastane.
- Colours: 4.

Speedo Swim Long Sleeve Hooded Shrug Top
Speedo is adopted by Olympic swimmers and world champions for a reason, fusing performance with fashion to create sleek, high-performing swimwear. And this hooded top? The peak of functional fashion. Layer your favourite swimming costumes with this stretchy shrug, delivering extra coverage as and when you need it. But the material is also chlorine-resistant and offers UPF50+ protection. A great option if you're not keen to invest in a whole new suit.
- Available sizes: XXS — XXL.
- Available lengths: N/A.
- Material: 83% polyester, 17% elastane.
- Colours: 2.

Seea Palomar UV Protection Crop Top Rashguard
If you're keen for coverage on your arms but don't mind a little flash of midriff, then this quick-drying crop top could be your best bet. With 20% spandex, this is one of the stretchiest options I tried, making it easy to get overhead. Although with no zip, removal was a two person two. I should also flag that you will have to buy the coordinating high-waisted bikini bottoms separately if you're keen to rock the entire co-ord. However, with 10 design options, I'd say this one takes the title of most aesthetic. And, for the less organised, it's available for quick delivery too.
- Available sizes: XS (UK 4-6) — XL (18-20).
- Available lengths: N/A.
- Material: 83% polyester, 17% elastane.
- Colours: 2.
Tropic Bodysuit Women Blue Long Sleeve One-Piece Swimsuit
Look to trusty surfer-favourite brand Billabong for long-sleeve swimsuits that will pop at the beach and beyond. I love the flattering printed panels on this long-sleeve, high-neck swimsuit, as well as the high-leg cut. Plus, with the zip on the back, some reviews say they felt a bit more secure, with no risk of their chest making a quick escape. Sadly, this one isn't so size-inclusive, and not all will appreciate the cheeky cut of the knicker. But for an extra layer while surfing on less pleasant days, it's a winner.
- Available sizes: XS (UK 6) — XXL (16).
- Available lengths: N/A.
- Material: 82% recycled polyester, 18% elastane.
- Colours: 2.
1.5mm Rise Natural Women Black Long Sleeve Springsuit
Those seeking a black long-sleeve swimsuit, I can confirm that you've got options. Sadly, it's those seeking a vibrant alternative that may struggle. However, Roxy has overdelivered with this polka-dot one-piece, suggesting, even to your fellow surfers, that you take note of current trends. Fitted with a high neck and offering full coverage on the bum, it's perfect for both wild swimmers and surfers seeking warmth. Most unique, though, is that horizontal front zip — essentially, while it might be harder to squeeze in and out of, you don't risk any irritation from an extra-long vertical zip.
- Available sizes: XXS (UK 4) — XXL (16 Tall).
- Available lengths: N/A.
- Material: 87% recycled polyester, 13% recycled elastane.
- Colours: 2.
Long-sleeve swimsuit FAQs, answered:
“They are also a total game-changer for long-term comfort,” continues Joanna. "Sun protection is the big one here — UV rays are much more intense when they’re bouncing off the water, and covering your arms and shoulders is the easiest way to avoid sun fatigue.
“You also get varying levels of warmth, from simple wind protection to the serious thermal insulation of natural rubber. For many, there’s a massive confidence boost in the extra coverage, too; since the suit is a one-piece, it’s designed to stay exactly where it should, no matter how much you move.”
“When it comes to the fit, the goal is a precise, ‘second-skin’ feel: it should be snug enough to support you but never restrictive,” details Joanna. “Think of it like a regular swimsuit that sculpts your body without causing any unwanted bulging or bunching. You’ll want to pay close attention to the ‘seal’ points at the cuffs and the neck. These should be a snug fit to stop water from ‘flushing’ through the suit, which is how you maintain that lovely thermal warmth. That said, it still needs to be flexible enough to wear comfortably for a full day at the beach.”
Aside from a flattering fit, pay attention to technical features — and for the eco-conscious, you'll want to consider sustinable fabric choices too. “High-performance suits often feature seamless underarm zones to prevent chafing, and many now utilise recycled materials like ECONYL or Yulex made with natural rubber, which offer the same hard-wearing performance without the high environmental footprint of traditional neoprene,” explains Joanna.
“Material choice is key; while lightweight recycled fabrics are great for lounging, natural rubber provides excellent insulation for cooler conditions. Don’t overlook the practical bits, like a zip long enough to make getting in and out of the suit effortless. Whether you’re paddling out past the break or just lounging by the pool, a well-chosen, sustainably-minded suit lets you enjoy the water with total confidence and comfort.”

How I test the best long-sleeve swimsuits:
As you'd expect, it largely consists of going for multiple dips in each long-sleeve swimsuit. However, to test their design, durability and overall function, this was in different environments (the sea, indoor pools and plunge pools) at various times of the year.
While wearing each style, I reviewed it against the following criteria:
| Functionality | Was the swimsuit fit for purpose? Did I have any issues in terms of slipping, twisting or skin irritation? Was it unnecessarily absorbent? |
| Design | Is the swimsuit aesthetic and comfortable? How many options do I have in terms of colour and pattern? And what was each swimsuit made of — is the material chlorine and UV resistant, as well as quick-drying? |
| Price point | Would I be willing to spend that much again? Is the swimsuit good quality? |
| Delivery | How quickly did the swimsuit arrive, and what were the associated costs? |
As someone who fluctuates between a DD and an E, depending on where I am in my cycle, I just fall into large bust territory. As a result, I also considered how size-inclusive each style was.
Unsurprisingly, only the long-sleeve swimsuits that impressed made it into this edit. However, I also tried the following:
- Land's End Women's Long Sleeve Zip Front Tugless Swimsuit, £85 — True to size and cut colourway, but I wasn't a fan of the high neck, and found the zip irritated my (sensitive) skin.
- Cobalt Blue Crinkle Long Sleeve Rash Swimsuit, £45 — Great price point and fun design, but found it came up a little small. Plus, no option for petite or tall girls.

Why you can trust me:
I've been reviewing swimwear, underwear, shapewear, activewear, and wellness products, such as cotton underwear, sports bras, and period pants, for almost three years — that's one year at Women's Health and 18 months at Glamour. During that time, I've seen countless trends and advancements, as well as a boom in our options.
But to ensure I am an authority on functional fashion and menstrual health, I regularly attend press launches, read the latest journals and interviews, and chat one-on-one with sportwear designers, gynaecologists, women's health experts and brand founders, asking for their insight and wellness tips.
In terms of my personal experience, as a fluctuating DD/E cup, I too struggle to find one-piece swimsuits and bikinis that are both aesthetic and supportive. And while I tend to favour a full-cup or a tummy-supporting style, I was keen to try various long-sleeve swimsuits that offer a little more coverage and help protect me from the powers of the sun.
