Our SweatTech™ bands are built to make every drop count. By combining woven latex layers with curved compression rods, this tech targets your core and amplifies your body’s natural heat.
That means more sweat, more detox, and real visible results — all while shaping and supporting your waistline.
I love this vest 'cause I sweat, it holds me in, and it doesn't leave fat rolls anywhere. Best of all, you can't tell I have on a waist trainer. I look good in my workout clothes. I'm confident this vest was a great purchasing choice to help in my weight loss goals.

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.
