Best Athletic One-Piece Swimsuits for Women of 2026

"I’m about 5’9” and usually wear a size 14, so I chose the size 40 after reading reviews. It fits quite well, especially for my tall frame—I often struggle to find one-piece swimsuits that are long enough. This suit offers modest leg openings, thick and fully lined material, and is comfortable for lap swimming. I appreciate that it doesn’t have annoying bra cups, and the quality is excellent for the price. If you’re tall and looking for a modest, well-made suit, this is a fantastic option!"

"My daughter absolutely loves this swimsuit! The XS fits her 100 lb frame perfectly, and she finds it comfortable with great fabric quality. The adjustable straps help achieve just the right fit, and the suit stays put while swimming. It’s simple, flattering, stretchy, and easy to move in—we’d buy it again!"

"Overall, this is a solid basic swimsuit that lasted about four months of regular swimming before the fabric started getting a bit see-through from chlorine. The higher cut still provides full coverage and allows a full range of motion for training. There’s no built-in bra, but the fit matches the description and gives good comfort and mobility. For a season of swimming, it performed well without rapid wear and tear."

"I was looking for a suit that covered well, felt flattering, and stayed in place. This swimsuit absolutely delivered—it gave me full coverage with no awkward riding up and the fabric felt thick and high quality. I also appreciated how quickly it dried after swimming."

"As someone who swims laps regularly and has a hard time finding suits that fit a larger body type, I was very happy with this one. The suit had good seams, strong double lining, and a cut that made me feel slimmer. After a tough swim, it didn’t stretch out or ride up, and the coverage in the thighs and top was exactly what I needed."

"I’m 5'4”, 127 lbs, and a 34C, and the size 34 fit perfectly. I loved the modest leg openings and great butt coverage—no riding up at all! The fabric feels sturdy and the breast pads stayed put while swimming. My only tiny gripe is that the pads move around when washing, but overall, this is the best fitting suit I’ve owned."

"As a plus-size swimmer, I appreciate how well this suit fits and how comfortable it feels for both leisure and lap swimming. I love the supportive built-in bra cups that stay in place, and the fact that the fabric is mostly nylon gives me confidence in its durability and resistance to chlorine. The conservative leg cut is another bonus. After trying more expensive brands that didn’t last, I’m really happy with the quality of this suit and will likely purchase again."

"This swimsuit is exactly what I needed. It’s easy to put on and take off, even when wet, and I feel like everything is secure and held in place. The fit is fantastic, so I’ll definitely be coming back for more."

"I was really pleased with the look and overall fit, but as someone who’s very short, I found it was too long for my torso. The design is super flattering, so I wish it had worked out for me. I think it would be ideal for someone taller."

"I've purchased this suit twice because the fit and support are perfect for my pool workouts. After swimming three times a week for two months, the fabric still looks new and hasn't degraded. It also stays put during activity, which I love."

"As someone who's 5'2" and self-conscious, I wanted a suit that didn't show too much skin. This one is incredibly comfortable, stretches well, and offers excellent coverage. The built-in shelf bra prevents any accidents, and I'm glad I sized down for a snug fit."

"I'm 4'11" and wear an XS. I was worried about the length but it fits just right. The boyleg style prevents ride-up and gives great coverage. After a month of swimming laps four times a week, the suit still looks and fits like new—no fading or stretching. I always wash it on gentle and hang dry it. I plan to buy another in a different color!"

"I appreciate the well-made quality of this swimsuit and found it to be flattering despite its conservative style. Because I have a long torso, it's rare to find a one-piece that fits me, but this one did. However, it does run small—I suggest going up one or two sizes for the best fit."

"My daughter needed a suit for her swim team, and although she's usually a medium, I ordered a large after reading reviews—and it barely fits. This suit is very compressive with minimal stretch, but it offers good coverage and is ideal for training, just make sure to size up significantly."

"I'm 5'11'' and finding a swimsuit with the right torso length is tough, but this one fit—albeit tightly. The fully lined, high-quality material impressed me, but I had to return it because the straps dug into my shoulders. I would have gone up a size if the price hadn't increased."

"I absolutely love the way this suit fits—it's got the perfect amount of compression and supports my bust without any see-through issues. For me, sizing up was necessary; I usually wear a 26/28 in Arena and a 28 in Jolyn, but a 30 in this style was perfect. Just know it runs small, so plan on going up a size!"

"This swimsuit is ideal for serious swimmers—it offers great flexibility and comfort, and the design is really sleek. The only thing to note is that there's no built-in padding, which might feel different if you have a larger chest, but it's standard for racing suits that prioritize performance over extra support."

"The quality is definitely there and the suit looks really cute, but no matter what size I try, it just doesn't fit me because the torso is too short. The straps dig into my shoulders, even though I'm petite with a long torso. It's disappointing, since otherwise it's a great suit."

"I've been swimming for hours each week and this is the only suit I trust—it goes on easily, never rides up, and holds its shape and color even after months of use. I love that it’s not bulky and dries fast. I keep coming back to TYR because the quality and price are unbeatable."

"For someone who swims regularly, this swimsuit has held up against chlorine and frequent use far better than others. The material doesn’t thin out, the color barely fades, and the fit is flattering. I’m 5'5", 160 lbs and the size 38 fits just right for reference."

"I chose this suit for my swim team kid because it’s durable, doesn’t fade, and doesn’t stretch out. Just be aware—the fit can be snug and compressive, so sizing up may help. The fabric quality is excellent and worth it for athletic swimmers."

"I purchased the suit for my daughter, and she's really enjoying it. The fit is snug and supportive, exactly what you want for a tech suit, and she's been able to swim more confidently and even drop time in her races. The quality has been impressive, and it's held up well through multiple meets. I would absolutely recommend this for anyone looking for a reliable, well-fitting tech suit for competitions."

"For us, this suit has been a fantastic value—it lasts through the whole winter season and fits perfectly and comfortably for competitions. Definitely worth the investment for the quality."

"My daughter is new to competitive swimming and is very happy with this suit. We got her a size 26, but could probably have gone down to a 24. For reference, she wears a 28 in Jolyn. My older daughter also had this suit and it lasted about a year before showing wear, which seems normal. Overall, a good choice for the price!"

"I absolutely love this swimsuit! It's super comfortable, true to size, and the coverage is great, especially in the back. The halter top is really flattering, and I found it easy to fix the bra pads. For the price, the quality is impressive. I'd definitely recommend it!"

"As someone with a slightly long torso, I was glad to find adjustable straps that made the fit perfect. I wore it for 17 dives and the fabric held up extremely well—no seam issues at all. Quality and comfort are top-notch, so I'm very satisfied!"

"My daughter swims daily, so we need reliable gear. This suit provides excellent coverage, stays in place during practice, and is clearly durable. One thing to note: in our experience, it runs a size large, so we size down. Overall, it's a great option for active swimmers."

"I've been wearing this suit for several months, swimming 2-3 times per week in a chlorine pool, and it's still holding up perfectly. The quality is excellent and it fits snug. If I were to buy again, I'd probably go a size up, but I love how well it lasts."

"As a competitive swimming family, my daughters and I appreciate how these suits fit perfectly and hold up well. The girls love the vibrant colors and design, and we've found them to be more comfortable and durable than other brands."

"I usually go for Speedo, but I tried this TYR suit because it was on sale and had a unique color. I was happy to find that the sizing is accurate, the cut is flattering, and it stays put during laps. The fabric is thicker than Speedo, which adds extra support, and so far it's proved to be very durable."
