1. Sporti Active Double Cross Bikini Top + Hipster Bottom
The double-crossback design locks this top in place through every stroke — no adjusting, no shifting, no worrying. Paired with the Hipster bottom (full coverage that stays put during flip turns), this is the two-piece that serious female swimmers trust for daily training.
The most popular athletic bikini on SwimOutlet by a wide margin. Available in 25+ colorways for team matching. At Sporti pricing, replacing worn suits every season is painless.
What we liked
- Double-crossback locks in place through all strokes
- Hipster bottom stays put during flip turns
- 25+ colorways for team matching
- Lycra Xtra Life chlorine-resistant fabric
- Sporti value pricing
What to consider
- May run small — consider sizing up
- No adjustable support (fixed straps)
- Not fashion-forward styling
Love this suit for practice. The crossback stays put through everything and the price can't be beat for a training bikini.

Jolyn bridges fashion and athletic performance — the Tomcat top provides sporty coverage for swimming and water polo, while the Andy bottom offers full coverage that looks anything but frumpy. Bold colorways and seasonal limited-edition prints create a visual identity that stands out.
Unlike beach-only brands whose bikinis dissolve in chlorine, every Jolyn suit uses chlorine-resistant polyester. This is the bikini for swimmers who refuse to choose between looking great and training hard.
What we liked
- Fashion-forward prints that stand out poolside
- Chlorine-resistant polyester for daily pool use
- Tomcat provides sporty coverage for training
- Andy bottom: full coverage, flattering cut
What to consider
- Premium pricing vs. Sporti
- Runs small — size up recommended
- Limited availability in some prints
Runs small like other Jolyn suits. Straps are easy to adjust and top stays put even in waves.

The classic triangle bikini never goes out of style, and Jolyn's version delivers the timeless silhouette with chlorine-resistant fabric. The Midl bottom provides moderate coverage that sits between skimpy and full — the Goldilocks zone.
Adjustable ties for customizable support and noticeably higher construction quality than fast-fashion alternatives. This classic triangle design is rapidly growing in popularity.
What we liked
- Timeless triangle silhouette
- Chlorine-resistant unlike beach-brand triangles
- Midl bottom: moderate, flattering coverage
- Adjustable ties for customizable fit
What to consider
- Triangle tops offer less support than crossbacks
- Not ideal for competitive flip-turn training
- Premium JOLYN pricing
I like the triangle top for casual ocean swims and prefer the Jolyn Tomcat for serious competition.

Same athletic crossback and chlorine-resistant fabric as the Active version, with iconic "Guard+" branding. Beyond lifeguards, this set is popular with swim instructors and budget-conscious swimmers who want a quality training bikini.
Available in Black, Navy, and Red. UPF 50+ sun protection for long shifts on the stand.
What we liked
- Guard+ branding for professional use
- Same quality construction as Sporti Active
- UPF 50+ sun protection
- Budget-friendly for team ordering
What to consider
- Guard branding limits non-lifeguard appeal
- Fewer color options than Active line
- May run small
Great quality guard suit. Holds up well through a full summer of daily use on the stand.
— Verified Buyer on SwimOutlet.com5. Sporti Active Tie Back Bikini Top
Most athletic tops have fixed straps — if you need more bust support, you are out of luck. The Tie Back solves this with adjustable ties that let you tighten or loosen the fit.
The best athletic bikini option for women with larger busts who find crossback-only tops inadequate. Chlorine-resistant Lycra Xtra Life fabric for daily pool use.
What we liked
- Adjustable ties for customizable support
- Best option for larger busts in athletic bikinis
- Chlorine-resistant Lycra Xtra Life
- Sporti value pricing
What to consider
- Tie-back requires retying if loosened
- Less secure than fixed crossback for racing
- Halter style may cause neck fatigue in long sessions
Finally an athletic bikini top that actually supports larger busts. The tie-back makes all the difference.

Focused on aquatic facilities and swim programs: simple, functional, durable, priced for bulk ordering. The set is sold together (top + bottom) for simplified purchasing.
Ideal for swim schools, YMCA programs, and facilities outfitting staff on a tight budget. Straightforward design with Guard branding.
What we liked
- Sold as complete set — simplified ordering
- Priced for bulk/team purchases
- Durable polyester construction
- Guard branding for professional use
What to consider
- Basic styling — no fashion appeal
- Sizing runs small per reviews
- Screen-print Guard logo may peel over time
Flattering and my most comfy swimsuit. I sized up and it fits perfectly.

TYR's Durafast Elite is arguably the most durable swimwear material on the market — engineered for 300+ hours of chlorine exposure. The diamond-back opening provides excellent range of motion.
If longevity is your top priority and you want a bikini that survives the most demanding training schedule, this is built for it. Quick-drying and colorfade-resistant.
What we liked
- Durafast Elite: 300+ hours chlorine resistance
- Diamond-back for maximum range of motion
- Quick-drying, colorfade-resistant
- TYR competition-grade quality
What to consider
- Higher price than Sporti alternatives
- Sizing can be inconsistent (top runs large)

Stays securely in place during lap swimming. The Durafast material really does last longer than other suits.
— Verified Buyer on SwimOutlet.com8. Billabong Sol Searcher Bikini Collection
Authentic surf-culture DNA: designed for salt water, sand, and sun in ways pool-focused brands are not. Mix-and-match tops and bottoms (triangle, bandeau, high-waist, cheeky). Construction handles wave action and board contact.
Not chlorine-resistant — built for the beach, not the pool. For the surfer or ocean swimmer who prioritizes comfort, style, and salt-water performance over pool durability.
What we liked
- Authentic surf-culture construction
- Mix-and-match tops and bottoms
- Handles wave action and board contact
- Premium recycled fabrics
What to consider
- Not chlorine-resistant — not for pool use
- Nylon-spandex stretches out over time
- Premium surf-brand pricing
Love the Sol Searcher for beach days. Comfortable, stylish, and stays in place in the waves.

Buyer's Guide: How to Choose the Right Bikini
Athletic vs. Fashion: The Fabric Test
If you swim laps or work as a lifeguard, you need chlorine-resistant polyester (Sporti, JOLYN, TYR). If you primarily wear your bikini at the beach, nylon-spandex (Billabong, O'Neill) is softer and more comfortable. Polyester lasts 5–10x longer in chlorine.
Top Styles Explained
Crossback/racerback: stays put during swimming. Triangle: classic, adjustable, best for beach. Tie-back/halter: adjustable support for larger busts. High-neck: modest coverage for water polo and surfing.
Bottom Coverage
Full-coverage hipster: standard for training. Mid-rise (JOLYN Midl): balanced coverage and style. High-waisted: tummy coverage with retro look. Cheeky: beach wear, not practical for competition.
Frequently Asked Questions
What is the best bikini for swimming laps?
The Sporti Active Double Cross Workout Bikini Top paired with the Hipster Bottom is the top-selling training bikini on SwimOutlet. The crossback design locks the top in place through every stroke, the hipster bottom stays put during flip turns, and chlorine-resistant polyester lasts a full competitive season.
What bikini brands do swimmers recommend?
Competitive swimmers most recommend Sporti for value and training, JOLYN for fashion plus athletic function, and TYR for maximum fabric durability. For beach and surf, Billabong is popular. The key for pool swimmers is chlorine-resistant fabric which lasts 5 to 10 times longer than standard nylon-spandex beach bikinis.
How do I keep my bikini from riding up?
Choose a crossback or racerback top that stays secure during overhead strokes. For bottoms, full-coverage hipster styles with wider side panels resist riding up better than narrow cuts. Proper sizing is critical and chlorine-resistant polyester maintains its snug fit longer than nylon-spandex which stretches out over time.
