The waist trainer, when wrapped around your mid section, creates a compressing effect in your core. This increases the perspiration at your mid section by stimulating thermal activity. It mobilises your fat cells and allows toxins and impurities to leave the skin through perspiration.

The work our waist trainer is made from natural latex rubber, which is then encased within an exterior cotton layer and an interior cotton lining. These three layers work together to maximise the impact of the waist trainer, while minimising discomfort.

To ensure that the waist trainer sits firmly at your waist, there are four spiral steel bones stitched into the garment, any more than 9 bones makes the garment heavy and restricts activity. These steel bones prevent the garment from rolling up or moving around your waist. The bones are light flexible spiral steel bones that aid movement while reinforcing the garment.
