The Technology Behind Calia Swimwear: Fabrics and Fit Explained

Calia, the activewear brand co-founded by Carrie Underwood, is more than just stylish workout and swim gear. It’s engineered for real women who want both performance and polish. When it comes to swimwear, Calia stands out by integrating smart fabric technology and thoughtful design features that enhance comfort, fit, and durability. Let’s dive into what makes Calia swimwear so functional and flattering.


Innovative Fabric Technology: Built for Performance

Calia swimwear utilizes high-quality materials that are designed to withstand active use and the harsh elements of water, sun, and sweat.

1. Chlorine-Resistant Fabrics

Calia suits are made with chlorine-resistant fibers, which help the garments retain color, elasticity, and overall shape over time. This is especially crucial for women who swim frequently in pools, where chlorine can quickly degrade typical swimwear fabrics.

2. Fade-Resistant Colors

Sunlight and saltwater can cause vibrant swimwear colors to fade. Calia’s swim fabrics are tested for UV resistance to maintain their bold hues and prints throughout the season.

3. Shape Retention and Stretch Recovery

The brand uses a blend of nylon and spandex (often including Lycra® or other advanced elastane fibers) to create a supportive, snug fit that holds up after multiple wears. The stretch recovery also means the suit won’t bag out or sag after a few swims.


Fit and Design: Thoughtfully Crafted for All-Day Comfort

A major part of Calia’s appeal lies in its body-conscious construction. These suits are made to move with you—whether you’re diving into waves or relaxing on the sand.

1. Supportive Shelf Bras and Sewn-In Cups

Most Calia one-piece suits and bikini tops include sewn-in cups or shelf bras for modesty and support. The thoughtful construction means you don’t need to worry about slippage or lack of lift.

2. Adjustable Straps and Back Closures

For a truly personalized fit, Calia suits offer adjustable features—like tie-backs, sliders, or hook closures—so you can fine-tune your support based on your activity and comfort level.

3. Contour Seaming and Strategic Lining

Many styles feature contouring seams that enhance your natural shape, along with full lining for both comfort and opacity. These subtle details make the difference between a suit that looks good and one that feels amazing all day long.


Function Meets Fashion: Style with Purpose

While the technology behind Calia swimwear is robust, the brand doesn’t skimp on style. Each season brings fresh silhouettes, trendy prints, and versatile colors, but every piece still incorporates Calia’s signature performance-first philosophy.
