SaunaActive™ Technology – Harnesses your body heat for maximum fat burning.
Our SaunaActive™ technology strategically utilizes your own body heat to keep your metabolism permanently activated.
The special inner layer reflects heat back, forcing your body to expend more energy to regulate its temperature. This automatically increases calorie consumption – even with small everyday movements.
At the same time, the heat stimulates sweating, helping to flush out excess water retention, leaving you feeling lighter instantly.
Why It Works:
Increased Metabolic Activity & Calorie Burn
The reflected body heat forces your body to expend more energy for temperature regulation – helping you burn more calories, even without exercise.
Sweating & Reducing Water Retention
The heat activates your sweat glands, helping to eliminate excess water, leaving you feeling instantly lighter and more defined.
Sustainable Fat Burning
The increased energy expenditure keeps your metabolism active, ensuring calories are used more efficiently before being stored as fat.

Clinical Proof
“Heat exposure has been indicated to positively affect glucose metabolism. An involvement of heat shock protein 72 (HSP72) in the enhancement of insulin sensitivity upon heat exposure has been previously suggested. Our results show that PHA for 10 days improves glucose metabolism and enhances fat metabolism, without changes in iHSP72. Further exploration of the therapeutic role of heat in cardio-metabolic disorders should be considered.”
The observations made by the researchers are supported by previous studies that focused primarily on the long-term effects of heat use, demonstrating positive effects on the cardiovascular system, for example. "A sauna session is a physical strain. Its long-term positive effects are similar to sports activities," explains Ketelhut.

Frequently asked questions
Here You’ll Find Answers to Your Questions
How can clothing help with weight loss?
ThermoSlim’s sauna clothing uses advanced thermal layers that raise your core body temperature, activating your metabolism and stimulating fat-burning proteins like HSF1.
This means your body burns more calories — even during simple movements like walking, cleaning, or going about your day.
During workouts, the effect is amplified, helping you see visible results faster and with less effort.
Is It Comfortable to Wear?
Yes. The inside uses a thermal layer that makes you sweat, but the fabric is soft, stretchy, and adapts to your body without feeling tight or sticky.
It doesn’t cause irritation and the outer layer stays dry, so sweat stays hidden — even during everyday wear.
Isn't This Just Water Loss?
No — it goes beyond that. While you do lose some water weight through sweating, the real benefit is the boost in metabolism and fat-burning activation.
Thanks to the heat exposure, your body burns more calories — and that effect can continue even after you take it off. So it’s not just a short-term sweat fix, but real long-term support for fat loss.
Won't It Get Too Hot?
No. ThermoSlim™ is designed to raise your core temperature just enough to boost results — without overheating you.
It feels comfortably warm, not overwhelming, and you can always take it off anytime if you need a break.
Will It Really Fit My Body?
Absolutely. ThermoSlim™ is made to fit real bodies — not just model sizes. The material stretches and molds to your shape, giving you a snug, flattering fit that moves with you, not against you. Whether you’re curvy, athletic, or in between, it’s built to feel like it was made just for you.
Do I Still Need to Exercise?
The clothing works in daily life, turning everyday movements—shopping, cleaning, or walking—into fat-burning activities. However, wearing it during exercise enhances its effects, helping you burn calories faster and achieve visible results sooner.
Is ThermoSlim Suitable for Sensitive Skin?
Absolutely! The clothing is made from skin-friendly materials that do not cause irritation. It is breathable, preventing moisture buildup—ideal for sensitive skin.
What If I Don’t See Results?
We believe in our products! If you don’t notice any changes within 60 days, you can return it hassle-free and get your money back.
Will Sweating Feel Uncomfortable?
No! The material is designed to absorb sweat efficiently, preventing unpleasant dampness or sweat stains. You’ll feel dry, fresh, and comfortable all day long!
