When it comes to swim training, real swimmers know that not all suits are created equal. Thick strap training suits are the workhorses of the pool—designed for mileage, built for durability, and cut for athletes who live and breathe chlorine.
These aren’t fashion-first suits you see on summer vacation. These are the day-in, day-out training tanks worn by swimmers grinding through threshold sets, getting after it on the back half of a 10×400 IM, or just chasing a :29 on repeat in practice.
And while there are a lot of options out there, a few brands consistently deliver performance and longevity. Speedo is still the cultural and market leader, worn by Olympians and age groupers alike. But other brands—like Nike, Arena, Jolyn, and Sporti—are earning more traction with bold designs and dependable fabrics.
Here’s our roundup of the best women’s thick strap one-piece training suits—designed for swimmers who take the sport (and their gear) seriously.
