Why Thousands of Women Choose Mass & Slim Leggings
Waist-to-Ankle Shaping
The high-waisted design smooths your waistline while sculpting your hips, thighs, calves, and ankles.
Enjoy a sleek silhouette that works invisibly under clothing.
Clinically Tested Cellulite Support
In a 30‑day third‑party clinical study, participants experienced measurable reductions:
- Up to 3.2 cm around the hips
- Up to 2.3 cm around the thighs
For best results, wear your Mass & Slim Leggings 8 hours per day for at least 30 consecutive days.
Tourmaline® Micro-Massage Technology
Hundreds of small Tourmaline® ceramic beads are embedded directly into the fabric.
As you move throughout the day, these beads create gentle friction against your skin, producing a subtle micro-massage effect that helps support:
• healthy circulation
• lymphatic flow
• reduced fluid retention
• smoother-looking skin over time
Breathable All-Day Comfort
Made with a breathable bamboo-viscose blend that feels soft, lightweight, and flexible.
Customers frequently wear Mass & Slim Leggings 8–12 hours daily under scrubs, office attire, dresses, and everyday outfits.
No rolling.
No pinching.
No constant adjusting.
Mass & Slim Shapewear Leggings and Shorts: What’s the Difference?
Both products use the same Tourmaline® micro-massage technology and deliver the same core benefits. Leggings also provide additional support for calves and ankles, which many women find helpful if they experience leg fatigue or swelling after long days on their feet.
Choose based on your coverage needs.
Choose Shorts if you want:
• waist, hip, and upper-thigh shaping
Choose Leggings if you want:
• full-leg shaping
• calf and ankle support
• help with lower-leg swelling or fatigue
Many customers own both styles and rotate them depending on their outfit.

- Wear the shapewear 8 hours per day

What Customers Are Saying:
⭐️⭐️⭐️⭐️⭐️ 5/5
"What an amazing product. I have leg lymphedema from having lymph nodes removed, due to cervical cancer. Leg Lymphedema is normally treated by wearing an uncomfortable compression stocking. They don't work for me. This product stimulates lymphatic flow and is perfect for my needs!"
- Cheryl Couch
⭐️⭐️⭐️⭐️⭐️ 5/5
"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 trying the bra this time too."
