The things you worry about, answered
Will they roll down?
No. The high-waisted, seamless design stays put and doesn't roll down or pinch, even after hours on your feet.
Will they show under my clothes?
No. They sit smooth and flat under dresses, skirts, jeans, scrubs and work pants, so no one will know they're there. Under very thin or skin-tight fabric, pair them with a slightly heavier layer for the smoothest look.
Will they be comfortable on a long shift?
Unlike traditional shapewear that squeezes, Mass & Slim Shorts move with your body. The breathable, cooling fabric sits smoothly against the skin, made for 8 to 12 hour wear.
Will my tired, heavy legs feel lighter?
For women on their feet all day, the gentle support and Tourmaline® micro-massage help legs feel lighter and more comfortable throughout the day.

Plan your rotation
Why three pairs instead of one
The clinical study had women wear the shorts 8 hours a day for 30 days.* Consistency is the key, and the women who see the best results wear them daily. With the anti-cellulite shapewear shorts 3-pack, a simple rotation keeps one pair always ready. They are machine washable and dryer safe.

How the Tourmaline® micro-massage works
Hundreds of small Tourmaline® beads are embedded directly into the fabric. As you move through your day, the beads create a gentle, continuous micro-massage against the skin. That subtle stimulation helps support:
- Healthy circulation, keeping blood flowing through tired legs
- Lymphatic flow, for lighter-feeling legs
- Smoother-looking skin, softening the visible appearance of cellulite over time
How to wear them: wear one pair about 8 hours a day, every day, for 30 days. Rotate your three pairs through the wash. See the single Shorts page for more on the fabric.
Try the 3-Pack for 60 days
Wear them for 30 days (the length of our clinical study*). Not happy? You still have 60 days from delivery for a full refund, even if you've worn them.

FAQs
Tourmaline® beads create a massage effect that boosts blood and lymphatic circulation. The improved circulation helps to reduce cellulite and inches over time.
The Gray Mass & Slim Shapewear is designed to wear under clothes—true to U.S. sizing. Size up only if you’re between sizes.
The Black Mass & Slim Compression Leggings are outerwear with firmer compression, so we suggest sizing up one full size. Both lift, shape, and help improve circulation to reduce inches and cellulite over time.
Our products are clinically tested to show visible results within 30 days, with reductions of up to -3.2 cm in the hip area and -2.3 cm in the thighs. For best results, we recommend wearing the garment for 8 hours a day for 30 consecutive days, as per clinical studies.
Whether you're a nurse, new mom, or constantly on the go, Mass & Slim shapewear fits seamlessly into your routine, offering a lifting and shaping effect for a flattering silhouette.
