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.
