I often experiment because I have terrible back pain because of my work as a Housekeeper, but I am grateful to you for what you do that you wrote to me, I will not stop wearing a belt not only for that but also for my figure. I always wear a belt I don't have time for fitness but I move a lot.

works wonders

been wearing it around the home while doing chores and am sweating so much around the waist. Do not know if it is effective in helping lose weight but it sure does aid in sweating like sauna. Have recommended to my friends and family. love it because I don't really sweat much usually.


Good to keep slim waist

The Domyos sauna belt comes in one size and is easy to attach with the rib-tab. All you have to do is wear your sauna belt under your clothing and adjust it to size without creating creases to keep it from chafing. A perfect fit with the rip-tab fastener. Wearing it does not hinder movement - it offers excellent freedom of movement so you can wear it during any activity.

Common feedback

The odour of neoprene may be noticeable on purchase of the new product. Neoprene has quite a strong odour. However, our sauna belt, like all our products, meets quality and toxicology test requirements for the materials used in our products (French standards).


Belt that can be used to amplify sweating during sports activities and also improve the quality of your skin. Intensive perspiration hydrates and softens skin. We recommend combining the use of this product with regular physical activity and a balanced diet if you want to lose weight.

Complementary products

Sweatsuit, sweat jacket, sweat shorts.

How does it work?

Beware of preconceived ideas: sweating does not make you slimmer. The belt increases perspiration by amplifying sweating.Through loss of water, dead skin is eliminated and the quality of skin improved through hydration. To prevent the risk of dehydration, drink plenty of water after use. This belt also helps warm up muscles.

This garment has undergone washing and drying tests to ensure that it retains its shape and colour. These tests are regularly performed by an independent laboratory and allow us to ensure that our quality standards are always upheld.
