Anti-Cellulite Shapewear for Smoother-Looking Legs
“They are so comfortable. They hold everything in.” — Joan Z.
How It Works Tourmaline® Micro-Massage Fabric
Mass & Slim stands for Massage & Slimming. Shapewear and compression leggings that smooth, sculpt and lift the moment you put them on, while gently supporting circulation so you feel comfortable and confident.
The secret is in the fabric:
a breathable, cooling 3D fabric embedded with Tourmaline® beads.
The beads create a gentle micro-massage that helps support better circulation, which, over time, can help you lose inches & see smoother skin.
You'll not only see a lifted, improved silhouette right away, but also smoother skin and fewer inches in 30 days, based on third-party clinical studies.
Find Your Perfect Fit
Shorts for under dresses & skirts. Leggings for under pants & scrubs. Compression Leggings to wear as your outfit. All three use the same Tourmaline® micro-massage fabric.
Designed to smooth, support circulation and reduce the look of cellulite, all while you go about your day.
Real Women. Real Results.

What Our Customers Say
“I am a critical care nurse and these leggings are saving my legs. I am no longer feeling leg fatigue at the end of my shift which has alleviated my knee pain. In addition my legs look smoother. My husband noticed the back of my thighs appeared less dimpled and he was a skeptic. I am ordering a second pair and I am going to try the bra this time too.”

What Our Customers Say
“These are wonderful, they really sculpt your body. I put them on every day and I don’t even feel them, they are super comfortable. As soon as I put them on, I feel slimmer already. I’m on my first week and I can already see it working, once I take them off I feel lighter and noticed less cellulite. I swear they’re helping me lose weight also. I am so happy with this purchase, and I highly recommend it!!”
