Swimwear isn’t just about fashion—it’s performance gear, too. Whether you’re training, aqua jogging, or racing, the right suit makes a difference. Let’s break down the three most common types of functional swimwear: Training Suits, Aquafit Suits, and Tech (Racing) Suits.
Training Suits: The Everyday Workhorse
Training suits are built to last through countless hours of pool time. They're made with durable polyester or polyester blends that resist chlorine and sun damage. Think of them as the “gym clothes” of swimwear—practical, supportive, and comfortable for day-in, day-out use.
These suits come in many styles: thin strap, thick strap, high cut, and more. While they hug the body closely for reduced drag, they’re not compressive like tech suits.
Typical Materials: 100% polyester, polyester/PBT blends.
Best For: Swim practices, fitness swimming, youth team training, and recreational lap swimmers.
Aquafit Suits: Designed for Movement and Support
Aquafit suits are ideal for water aerobics, aqua jogging, and low-impact water exercise. They usually feature built-in bras, modest leg cuts, and a bit more coverage overall. These suits are designed with support, comfort, and freedom of movement in mind—without the compressive squeeze of performance suits.
Most Aquafit suits prioritize chlorine resistance, and many are made with UV-protective fabrics for outdoor pools. They’re often lined in Canada and the U.S., whereas in some European designs, lining may be omitted for a lighter feel.
Typical Materials: Polyester/spandex blends, chlorine- and UV-resistant fabrics.
Best For: Water fitness classes, lap swimming with less intensity, and those seeking coverage and comfort.
Tech Suits: Built for Speed and Performance
Tech suits (also called racing suits) are engineered for competitive performance. They’re ultra-lightweight and compressive, made with water-repellent fabrics and bonded seams that reduce drag. Designed to support muscle engagement and streamline the swimmer’s form, they’re worn by athletes during races—not practice.
These suits typically come in jammer or kneeskin styles and are often FINA-approved. Due to their tight fit, they take time (and sometimes help) to put on and are not meant for everyday use. Most tech suits are unlined or minimally lined to maintain lightness and hydrodynamic advantage.
Typical Materials: Polyamide/elastane blends, hydrophobic microfibers, carbon-infused fabrics.
Best For: Competitive swimmers during meets, time trials, or any event where milliseconds count.

Cultural & Regional Variations
In Canada and the U.S., most women's training and Aquafit suits are lined for modesty and support. In contrast, many European brands skip full linings, focusing more on feel and hydrodynamics. When shopping internationally, this can be a surprise—so always check the product description if coverage matters to you.
