Define Vest Duo

Yes! Our bands use a safe level of compression to shape while providing support. They’re breathable, flexible, and designed to move with you. Our products are safe to use, but if you have any medical conditions, we recommend consulting your doctor.

We didn’t just create a product—we created a solution. We started by sizing hundreds of real women with real bodies, because we’ve been there too. We know what it feels like to want support, comfort, and confidence in your body. As a women-owned and operated brand, we design every band with your needs in mind—products that work, feel good, and help you show up as your strongest, most confident self.

Our size chart is over 95% accurate, built from years of fitting women of all shapes and sizes. If it feels snug at first, that’s normal—the band molds to your body and becomes easier to put on with use. We also offer 30 day exchange to help you get the prefect fit.

The Define Band is multifunctional. Use it during workouts or wear it under or over clothes for shaping, posture correction, and back support—whether you’re at work, running errands, or relaxing at home.

Start with a few hours a day and increase as your body adjusts. Most users feel comfortable after just a few days of wear.

With consistent use, many customers report seeing results in two weeks or less—especially when paired with a healthy lifestyle.
