Good product

It was a tad long, so i cut it and it worked well too. Apart from the sauna effect, i felt like it gave my back a little bit of support as well. Material is soft and comfortable. It survived many washing machine washes, just make sure to put it in a net.

All you have to do is wear your sauna belt under clothes, and adjust it to size without creating creases, to prevent irritation. A perfect fit with the rip-tab fastener. Wearing it does not hinder movement, quite the opposite, with the freedom of movement it offers, you can wear it during any kind of activity.

Common feedback

The odor of neoprene may be noticeable on purchase of the new product. Neoprene has quite a strong odor. 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 belt with regular physical activity and a balanced diet if you want to lose weight.

Complementary products

Sauna suit, sauna jacket, sauna shorts.

How it works

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 using this product. This belt also helps warm up muscles.



Product testing

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