What the AI looks for in Women's Athletic One-Piece Swimsuits
- Chlorine resistance
- Choose 100% polyester or PBT, or a fabric labeled chlorine-resistant, for regular pool use. Standard spandex suits lose shape quickly under frequent chlorine exposure.
- Back cut
- Open, thin-strap backs suit freestyle and butterfly. Closed or wider-strap backs give more support for larger busts. The back cut drives both strap security and shoulder freedom.
- Bust support
- If you need support, look for removable cups or a built-in shelf and wider straps. Basic training suits offer little support.
- Torso length
- Long-torso swimmers should look for long-torso or extended sizing where offered. A too-short torso causes painful strap pressure and riding up.
Brands that matter
- TYR: Durafast fabric is known for longevity.
- Speedo: Endurance+ is widely available in many cuts.
- Dolfin: Uglies prints and Chloroban fabric.
- Arena: MaxLife chlorine-resistant line.
What to avoid
- Fashion one-pieces with lightly lined spandex for pool training.
- Suits without any lining in light colors.
