Best Women's Athletic Swimwear AI pick

AI pick (line): Speedo Endurance+

For budget chlorine-resistant lap suit
Arena MaxLife (line)

Not for: Swimmers who want a soft, stretchy fit or a racing suit.
What the AI looks for in Women's Athletic Swimwear
- Fabric vs. chlorine
- For several pool sessions a week, choose 100% polyester or PBT, or a fabric labeled chlorine-resistant such as Xtra Life Lycra, over standard nylon-spandex. Chlorine breaks down elastane, so ordinary suits bag out, go sheer and fade within weeks of regular training.
- Sizing of polyester suits
- Check the brand's size chart. Polyester training suits stretch much less than fashion suits and often fit snugger than your usual size. A suit that fits like a fashion suit in the store can be too tight across the torso in polyester.
- Back style and strap security
- Match the back to your stroke: thin crossed or open backs for freedom, and wider or closed backs for more support and less strap slip. Straps that slide off during flip turns or butterfly are the most common fit complaint in training suits.
- Lining
- Look for a front lining at minimum, and full lining in light colors. Unlined light-colored suits can become see-through when wet.
- Racing legality
- For sanctioned meets, check that tech suits carry World Aquatics approval. Unapproved suits can be ruled illegal at competitions.
Brands that matter
- Speedo: Widest range of training and racing suits, with the Endurance+ line for chlorine resistance.
- TYR: The Durafast line is a durable, chlorine-proof training staple with many back styles.
- Arena: Strong in both training (MaxLife) and racing (Powerskin).
- Dolfin: Known for Uglies printed chlorine-resistant suits for team and lap swimmers.
- Jolyn: Athletic two-piece and training suits built to stay in place during water sports.
What to avoid
- Nylon-spandex fashion suits used for daily pool training.
- Unlined light-colored suits.
- Racing tech suits worn for everyday practice, which wears them out quickly.
Questions
Why does my new suit feel too tight?
Chlorine-resistant polyester has far less stretch than spandex. Use the brand's chart rather than your street size.
