They do not feel hot at all. Let's see what the next 30 days do. I am impressed so far!" -SOPHIA MARIANNA GRAZIANO

FAQs
Q: Which Mass & Slim product is right for you?
A: Every Mass & Slim product uses the same Tourmaline® micro-massage technology. The difference is coverage and how you wear them:
Mass & Slim Shapewear — Worn UNDER Your Clothes (Gray)
Discrete, comfortable shaping that goes smoothly under any outfit. Wear them 8–12 hours a day without anyone knowing. If you're between sizes, we suggest sizing up for the most comfortable fit.
Shapewear Shorts ← You're viewing this product
-
- Shapes waist, hips, and upper thighs
- Perfect under dresses, skirts, and shorter hemlines
- Lightest coverage — ideal for warmer weather or layering flexibility
-
- Full-length shaping from waist to ankle
- Tucks smoothly under pants, jeans, and longer outfits
- Added support for calves and lower legs
-
- Targeted waist and midsection support
- Pairs with any bottom — shorts, skirts, or pants
- Most focused compression for the core area
Compression Leggings — Stylish Outerwear (Black)
Fully opaque, stylish leggings you can wear on their own; to the gym, running errands, or out and about. These have firmer compression than our shapewear, so if you're new to compression leggings, we suggest sizing up one full size from your usual U.S. size.
-
- Fully opaque, squat-proof, and gym-ready — designed to be worn on their own
- Firmer compression for maximum sculpting and lifting from the waist to the ankle
- Best for workouts, long shifts, errands, or anyone who wants the strongest hold
Which one should I get?
Go with Shapewear if you want comfortable, discreet shaping you can wear under your everyday clothes — pick from Shorts, Leggings, or the Waist Shaper depending on what you're wearing over them.
Go with Compression Leggings if you want stylish, high-compression leggings you can wear on their own — to the gym, on errands, or anywhere you'd wear your favorite leggings.
Can't decide? A lot of our customers own both — grey shapewear for everyday layering under clothes, and black compression leggings for days when they want that extra sculpt and support on full display.
Q: Can I wear them all day?
A: Yes. The breathable bamboo-viscose fabric is designed for extended wear. Many customers wear them 8–12 hours daily.
"So comfortable, you can even sleep in them."
Q: Will they make me feel hot?
A: No. The bamboo-viscose fabric is breathable and cooling — comfortable even in warmer climates.
Q: Will they show under my clothes?
A: No. The seamless, high-waisted design sits smoothly under clothing without adding bulk.
Q: What if they don't fit?
A: We offer 60-day risk-free returns and free size exchanges.
Q: How do the Tourmaline® beads work?
A: Tourmaline® ceramic beads are embedded in the fabric. As you move, they create a gentle micro-massage effect that may help support circulation and promote smoother-looking skin.
Q: How soon can I expect to see results?
A: The shaping effect is immediate. For the appearance of cellulite, we recommend 8 hours/day for 30 days. Many report visible improvements in 4 weeks.
Q: Suitable for busy lifestyles?
A: Perfect for nurses on 12-hour shifts, busy moms, and professionals. Comfortable enough to forget you're wearing them.

Mass & Slim Shapewear Leggings and Shorts: What’s the Difference?

Many customers own both styles and rotate them depending on their outfit.

⭐️⭐️⭐️⭐️⭐️ 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

"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."

Mass & Slim Compression Leggings combine firm sculpting compression with Tourmaline® micro-massage technology to help support circulation, smooth the appearance of cellulite, and help reduce inches over time.
Unlike typical compression leggings that simply squeeze, Mass & Slim works with your body’s movement to provide both instant shaping and gradual improvements with consistent wear.
These are fully opaque outerwear leggings — designed to be worn confidently at the gym, running errands, or anywhere you want sculpted, smooth-looking legs.
What Does Mass & Slim Mean?
Mass & Slim stands for Massage and overall Slimming.
The technology works in two ways:
Massage: Embedded Tourmaline® ceramic beads create a gentle micro-massage effect as you move, helping support circulation and lymphatic flow.
Slimming: The sculpting compression fabric shapes, lifts, and smooths your waist, hips, thighs, and calves for a visibly slimmer silhouette.
Together, these two actions help reduce apearance of cellulite and improve body contouring over time.
Why Women Love Mass & Slim Compression Leggings

They help shape and lift:
• waist
• hips
• thighs
• calves
The result is a smooth, confident silhouette that looks as powerful as it feels.
Active Cellulite Support Technology

In a 30-day third-party clinical study, participants experienced measurable reductions including:
• up to 3.2 cm around the hips

Individual results may vary.

Unlike traditional shapewear, these leggings are designed to be worn as outerwear.
