Why Thousands of Women Choose Mass & Slim Shorts
Instant Shaping
The high-waisted design smooths the waistline and shapes the hips right away. The seamless structure sits invisibly under dresses, skirts, pants, and everyday clothing.
Clinically Tested Support
In a 30-day third-party clinical study, participants experienced measurable improvements:
- Up to 3.2 cm around the hips
- Up to 2.3 cm around the thighs
For best results, wear your Mass & Slim Shorts 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, these beads create gentle friction against the skin. That subtle micro-massage effect helps support:
-
- Healthy circulation
- Lymphatic flow
- Smoother-looking skin over time
Breathable All-Day Comfort
Made with a breathable bamboo-viscose blend that feels cooling and soft on skin. No rolling. No pinching. No constant adjusting.
How Mass & Slim Works

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.
