Best Women's Swimsuits (2026)
Three suits built to actually last, and an honest note on what PBT fabric feels like.
The short answer
The Speedo Women's Endurance+ Super Pro is the best women's swimsuit for regular swimming: 100% chlorine-resistant PBT fabric that outlasts standard swim fabric several times over. For a long torso, TYR's Durafast Elite Maxfit is cut longer in the back and does not dig at the shoulders.

PBT is the whole story
If you swim in chlorine regularly, fabric is not one consideration among several — it is the consideration. A standard swimsuit is roughly 80% nylon and 20% elastane, and chlorine degrades elastane. The suit goes slack, then thin, then translucent, and it happens within a season of regular use.
PBT — polybutylene terephthalate — is a polyester relative that chlorine barely affects. Speedo markets its version as Endurance+, TYR as Durafast Elite. A 100% PBT suit routinely lasts several times longer than a nylon-elastane suit in the same pool, which makes it cheaper per swim despite costing roughly double up front.
The honest trade-off: PBT stretches less and feels firmer out of the packet. It takes a few swims to soften and it never has the smooth drape of a fashion suit. For lap swimming that is irrelevant and arguably better, because the compression holds. For a suit you will wear sitting on a beach, it is a real comfort cost.
Speedo Women's Endurance+ Super Pro
Endurance+ fabric is the genuine article — it outlasts standard swim fabric several times over in chlorine.
Specifications
- Fabric
- Endurance+ (PBT), 100% chlorine-resistant
- Back
- Super Pro, high coverage
- Sizes
- Women's 28-40
- Lining
- Fully lined
What works
- PBT fabric does not degrade in chlorine — the fabric, not a coating, is what makes this last
- Super Pro back holds the shoulders without cutting in over a long swim
- Holds compression across a full season rather than going slack
- Fully lined, so it stays opaque wet
What doesn’t
- PBT has less stretch than standard swim fabric and feels firmer
- Costs roughly double a fashion one-piece
Who it’s for
A woman swimming laps weekly, or anyone tired of replacing a suit every summer.
Bottom line
Cheaper per swim than any fashion suit. If you swim in chlorine regularly, this is the only sensible fabric.
TYR Women's Durafast Elite Maxfit
TYR's chlorine-proof Durafast Elite in a longer-cut back, for swimmers a standard suit cuts into.
Specifications
- Fabric
- Durafast Elite, chlorine-proof
- Back
- Maxfit, open
- Sizes
- Women's 22-40
- Lining
- Front lined
What works
- Durafast Elite resists chlorine, sunscreen and salt, which is more than most fabrics claim
- Maxfit back is cut longer, so it does not dig at the shoulders on a long torso
- Open back stays cool on outdoor swims
- Genuine size range including smaller and larger sizes
What doesn’t
- Open back gives less sun coverage on the shoulders
- Firm fabric takes a few swims to soften
Who it’s for
Regular swimmers, especially anyone who finds standard one-pieces too short in the body.
Bottom line
The alternative to Endurance+, and better if a standard suit cuts into your shoulders. Both fabrics are the real thing.
Snapper Rock Girls' Long Sleeve Sunsuit
A long-sleeve one-piece sunsuit — swimsuit and rash guard in a single garment, so nothing rides up.
Specifications
- UPF
- 50+
- Sleeves
- Long, integrated
- Closure
- Back or front zip
- Sizes
- Baby through youth
What works
- One garment means no gap at the waist where a rash guard rides up and burns
- Zip closure is far easier than peeling a wet two-piece off a child
- Covers shoulders and upper arms, where kids burn worst
- Chlorine and saltwater resistant
What doesn’t
- Warm on a genuinely hot day
- One-piece long-sleeve designs are awkward for toilet trips
Who it’s for
Children on all-day outdoor water days, especially fair-skinned ones.
Bottom line
Best total coverage of anything here. For a full day in open sun this beats a suit-plus-rash-guard combination.
What to look for in a women's swimsuit
Fiber content. Look for 100% PBT, or polyester with under 20% elastane, if durability matters. Everything else is a fashion fabric regardless of what the marketing says.
Back style, chosen for what you do. A high-coverage back (Speedo's Super Pro and similar) holds the shoulders without cutting in and gives more sun coverage. An open or cross back is cooler and gives more shoulder rotation, which suits outdoor swimming and freestyle. Neither is better in the abstract.
Torso length. The single most common women's fit complaint is a suit that digs at the shoulders, and it is almost always a long torso in a standard-length suit. Brands cut differently and TYR's Maxfit range is specifically longer. No amount of going up a size fixes it.
Full lining. Keeps a suit opaque when wet and adds structure. Front-lined is the minimum; fully lined is better.
Real size range. Training brands generally size by chest measurement in inches and cover a wider range than fashion brands, which is worth knowing if standard sizing has never worked for you.
How much should you spend?
Work in cost per swim rather than sticker price. A PBT suit at roughly double the price of a fashion suit that lasts three or four times as long in chlorine is straightforwardly cheaper, and the gap widens the more you swim.
If you swim a handful of times a summer in a lake, none of this applies — buy whatever fits and is comfortable. Chlorine is the destructive agent, and lake water plus sunlight is far gentler.
Two suits is again the right answer for a regular swimmer, and for a specific reason beyond having a dry one: alternating suits roughly doubles how long each lasts, because the fabric gets time to recover between swims.
Will it last a second summer?
A PBT suit swum three times a week will commonly go two to three seasons. A nylon-elastane suit in the same use often does not finish one. That is the whole argument for the fabric.
Care, which matters more than most people think: rinse in cool fresh water immediately after every swim — chlorine left in the fabric keeps working. Hand wash or wash cool, never use fabric softener, never wring, and never tumble dry. Dry flat in shade, not hanging in sun, because both heat and UV degrade elastane.
And avoid sitting on hot rough surfaces. Abrasion on the seat and heat from concrete are what finish suits that the chemistry would have spared.
