Our core compression technology is the result of two decades of fit innovation, performance fabric engineering, and an unmatched understanding of how to smooth, shape, sculpt and support a woman’s body without sacrificing comfort.

We use a strategic combination of fabric weights, seamless construction, and zoned compression to deliver targeted shaping exactly where you want it—and nowhere you don’t.

SPANX uses zoned and targeted areas where you need them so you have freedom in the areas you don't. 
Most brands apply compression evenly, which can feel restrictive and unflattering, or they add overly constructed elements to deliver on targeted areas. Our specific targeting lives behind the scenes—built into seams, waistbands, and even fabric blends—so you get powerful shaping without bulk, stiffness, or discomfort.

It's also engineered by real women, for real women. Our design process starts with real feedback and 
real bodies—not mannequins. Every product is tested on a wide range of shapes and sizes to ensure our compression supports curves, rather than fight them.

We choose comfort first, sourcing premium performance fabrics that offer both high compression and 4-way stretch, so you can move, sit, and breathe without losing the shape you came for. The result is a totally different wearing experience. Our compression doesn’t just hold you in—it lifts you up. It enhances your natural shape, eliminates distractions, and lets you focus on living your life—not adjusting your clothes.

We’ve added the SPANXeffect™ compression levels at the beginning of our product names so you can better find what level is right for you at quick glance.

When shopping for a specific product, we also made sure to add visual cues through custom icons that showcase where in the range of the SPANXeffect™ that product sits. You can find that in the Why We Love It section of our product detail pages.
