Best Athletic One-Piece Swimsuits for Women of 2025

"I was in a bit of a pinch when my daughter suddenly needed a swimsuit for an upcoming outing! We found a few options with great reviews and eye-catching designs. The fabric felt soft yet durable, and the fit was just right for my 13-year-old, giving her both comfort and confidence. It held up perfectly while she was being pulled on a tube behind a boat, providing the right amount of coverage and support. Seeing how much she loved it, I'm definitely inspired to purchase one for myself soon!"

"I can't express how positive my experience has been with this suit from Baleaf. It fits well and has held up remarkably over time. I swim or do water aerobics four days a week, and I've been using this suit for over a year, with it just beginning to show signs of wear. It's especially impressive for the price, and although it lacks some coverage in the bust, I ordered a second one in a different color because I'm so happy with it!"

"I moved into a building with a lap pool, so I needed some athletic swimsuits. I bought this one in a lovely dark purple. The quality is good, especially for the price, and the seams are well-stitched. However, I noticed the suit has a strangely thick black lining that can bunch unattractively, particularly when my skin is damp. Adjusting the straps has also been a bit challenging for me. Despite these minor issues, I still appreciate the quality and color!"

"I’m absolutely thrilled with this swimsuit! The print is fantastic, and the quality is on par with high-end brands I've owned. I'm so pleased with this purchase."

"This suit is well-made and fits me perfectly. It's fantastic for swimming laps, and I've spent twice as much on similar quality suits. I was so impressed, I ordered a second one in black!"

"Upon trying it on, I was excited to find a suit that fit well up top and offered modest coverage. However, the bottom felt a bit too loose for my liking. I bought a 2XL, and while it fits my bust, it has extra fabric that just hangs on me. If you’re longer waisted or have a larger bottom, it might work better for you!"

"I was looking for a bathing suit that fit well, and this one is perfect. The quality is really nice, and I love the vibrant color. It fits overall well, but I found it runs a bit small. At 5'1" and 120 lbs, I got a size 34, but I think a 36 would have been better. I'm definitely ordering more colors!"

"I bought this suit for my 12-year-old who is joining a swim team. She's about 5' and 125 lbs, and I got a large based on reviews. It barely fits, but it works. I understand it's a compression suit, and it doesn't have the stretch of a normal suit. After two hours of wearing it, there were no complaints, and I appreciate the reasonable price of 20 bucks!"

"As a competitive swimmer, I understand the sizing can be tricky. This is a competition style swimsuit, and I ordered my usual size of 34. It fits like a glove, providing full coverage and a snug feel, which is ideal for reducing drag in the water. If you're looking for a suit to lounge in, this isn’t it, but for workouts, it’s perfect!"

"I think this may be the nicest bathing suit I've ever owned. The material is thick, well made, and very easy to put on. It fits perfectly. I'm a size M, and it fits true to size. It provides full coverage and is perfect for swimming laps at my gym. Love it!"

"After having three kids, finding a swimsuit that offers great coverage was challenging. This suit helped me feel comfortable at the public pool. I swim about 1,000 yards 2-3 times a week, and the suit is performing beautifully. No chafing, and it holds its shape and color in harsh chlorine. It fits as expected, even with my long waist!"

"I was searching high and low for a swimsuit that wasn't too revealing, and this is it! It covers everything I want and is really comfy. The color has not faded after a few months, and it’s lightweight, with the elastic holding up well. I will definitely buy it again!"

"I bought this suit for its gorgeous burgundy color. At 5'3" and 108 pounds, the size 32 fits perfectly. It feels great, lined in black, and is much easier to put on than my previous Speedo suit. I enjoy this nylon/lycra suit!"

"As a fitness swimmer for 20 years, I've tried many brands. I ordered this fantastic suit based on good reviews, and it fits true to size. I love the thinner straps and flattering fit. It’s fully lined, which was a pleasant surprise!"

"I’m 5'9" and 150 lbs, and I ordered a size 36. It was a bit tight, but I kept it because I prefer a snug fit for lap swimming. After a couple of swims, I regretted not returning it, but it’s still a flattering, high-quality suit."

"I purchased this suit in January to join my lifeguard son at his 'Mamaw and Papaw class' where mature adults have open swim at the local high school pool. It's perfect and as an avid swimmer, this suit has stood up well the last 6 months. I appreciate the longer leg cut, as I have an apron belly after two c-sections and struggle to find bottoms that cover adequately. The boy leg cut of this suit covers everything perfectly while still looking like a regular suit. Perfect for plus-size ladies. I do advise measuring yourself and not sizing down. I've used it at least three times a week, and there's been no color loss or elastic issues. Bless you Speedo, this one's a keeper!"

"I swim a few miles a week and wear a size 8. I've been ordering these Speedo suits for at least 10 years, alternating between navy and black, and I always have a backup. They last around 8 months with continual use due to chlorine bleach out and normal wear. I love the fit; they're lined, made of great material, and have a built-in soft bra. Great for flip turns and have a conservative fit. I just turned 60 and have used them throughout my 50s."

"I was initially thrilled with the fit and cover of this suit. I bought two black ones for swimming and aqua aerobics, and they felt great. However, after only 2-3 months of use, I noticed white fiber breakage appearing. When I returned to my suit after some travel, it had degraded significantly and felt tacky to the touch. I ended up using a backup suit, but it experienced the same issues. I'm disappointed as I expected better longevity from this brand."

"I needed a bathing suit for swimming laps, and I hate how high cut most women's bathing suits are. This is exactly the cut and shape I wanted, and the material is wonderful. It's double lined throughout, and durable enough to be an athletic bathing suit. I'm 5'2" and 105 lbs, and the x-small fits perfectly. When this one wears out, I'm buying another identical one to replace it with."

"I just received my swimsuit, and while it looks good and fits well, the boyleg openings are too big. I'm going to sew them smaller by about two inches each. I'm 5'6" and weigh 118 lbs, ordered a small, and so far overall, I'm quite pleased."

"I swim laps three times a week for about 40 minutes, and while the suit initially looked great, it has started to pill and sag after only three months. I've rinsed it thoroughly after each swim, so I believe I've taken proper care of it. It was comfortable and a good fit, but I expected it to last much longer."

"I had no idea swimsuits could fit this well. After trying many styles and brands, this one is honestly perfect! The compression is just right, not loose at all but also doesn't pull at my shoulders. The fabric is high quality and completely opaque. I did find that this suit runs small, so I ordered a size up, and it fits perfectly!"

"I found this Speedo swimsuit to be a great choice for serious swimming. It's designed for performance and offers flexibility and comfort. However, I should mention that if you have a larger chest, it lacks built-in padding, which might feel a bit different than other swimsuits."

"I haven't used it for swimming yet, but I want to warn others that it runs small. I ordered the same size as another Speedo swimsuit I have, but this one is much smaller. Despite that, I really like the suit overall."

“I absolutely adore this suit! It fits perfectly and is perfect for my lap swimming routine five days a week.”

“After a year of use, I can say it holds up well. I ordered a size 10 long and it fit nicely despite some weight loss. The quality is impressive, and this is the first comfortable one-piece I've found. I'm reordering because I'm so pleased!”

“I'm thrilled to have found a suit that fits well and is adorable. The fact that it’s not just black or navy is a huge plus for me. I’ll make sure to wash it properly after every use to maintain its color.”

"I took a chance and bought this for vacation. The suit seems very nice and fits great. It’s thicker material than I expected, and I love the adjustable straps. It fits better than most I’ve tried on. Time will tell how long it holds up, but as of now, I would totally recommend it."

"This has been a fantastic competition suit for me. It fit as expected, the material is good, and it is comfortable. I feel great in it!"

"I really like it a lot. The high neckline is perfect because I can swim without worrying about my boobies popping out. I have large breasts, so finding a comfortable suit is tough, but this one works. I wish it covered my armpit better, but overall, it’s livable. I appreciate the built-in padding and adjustable straps."
