Our review of the TYR Women's Durafast Elite Diamondfit Swimsuit finds it best suited for swimmers who need a low-maintenance, long-lasting training suit. The biggest reason to buy is its Durafast Elite textile, a polyester-rich fabric that combines chlorine resistance and colorfastness with a comfortable stretch for hours in the pool. The suit offers a medium neckline, sleek straps, a keyhole back and a moderate cut leg that provide reliable coverage and a secure, no-fuss fit for lap swimming and practice.
Key Features
- Durafast Elite fabric: Built from high denier poly fiber and circular knit construction to deliver strong chlorine resistance and long-lasting color retention.
- Comfort stretch blend: The 94% Polyester and 6% Spandex mix gives a comfortable hold that moves with the swimmer without sagging after repeated use.
- Performance fit: Medium neckline, sleek straps and keyhole back provide secure coverage that stays in place during laps and practice sets.
- UPF 50+ sun protection: Fabric construction adds sun protection for outdoor training sessions while maintaining performance in the water.
- Lined for freshness: All Durafast Elite suits include a lining designed to reduce odor and extend use between washes.
Who It's For
The Diamondfit is ideal for competitive swimmers, swim team members, and regular lap swimmers who prioritize a suit that lasts through heavy chlorine exposure and frequent training. Its combination of sturdy polyester and modest cut makes it practical for daily practices where durability and reliable coverage matter.
Swimmers who want a fashion-first or highly compressive racing suit should look elsewhere; this suit emphasizes longevity and comfort over extreme speed suits or decorative seasonal prints. Also, buyers who prefer a very loose or very tight custom fit may need to check sizing carefully, since some users report mixed sizing impressions.
