In this review the TYR Women's Durafast Elite Diamondfit Swimsuit is evaluated as a straightforward, performance-focused one-piece for lap swimmers and swim teams who need long-lasting coverage. The single biggest reason to buy is its Durafast Elite fabric, which pairs high denier polyester strength with stretchy spandex to deliver a chlorine and colorfast suit that keeps a snug, secure fit through extended pool use. The reviewer found it comfortable for repeated sessions and praised the fabric's ability to retain color and structure after many hours in chlorinated water.
Key Features
- Durafast Elite fabric: Provides exceptional chlorine resistance and color retention so the suit stays vibrant and reliable after 300+ hours of use.
- Circular knit construction: Combines high denier polyester with spandex for a strong yet flexible fabric that maintains shape without feeling heavy in the water.
- Design and fit: Medium neckline, sleek straps, keyhole back and moderate leg cut give secure coverage ideal for practice and lap swimming.
- Lining for freshness: All Durafast Elite pieces include a lining that helps control odor and maintain comfort during frequent use.
- UPF 50+ protection: Built-in sun protection reduces UV exposure for outdoor training sessions while remaining performance oriented.
Who It's For
The TYR Diamondfit is best for competitive swimmers, swim team members, and regular lap swimmers who prioritize durability and consistent fit over fashion-forward styling. Athletes who swim frequently in chlorinated pools will benefit from the suit's proven colorfastness and the secure hold the design provides.
Swimmers who prefer a very high-cut leg, fashion swimwear, or a softer, less snug casual suit may want to look elsewhere, as this model aims for performance hold and longevity rather than leisure comfort or runway styling.
