The faja sports vest is more commonly known the work out waist trainer or gym sports latex waist cincher.

These have been worn by various celebrities including Kim Kardashian, Amber Rose and Khloé Kardashian to reshape their waistline and aid weight loss.

This purple work out waist trainer will look great in the gym or wherever you chose to wear it.

It can be worn anytime you are going to active, be it at the gym for an intense work out, or when you are just going for leisurely stroll. Let the work out waist trainer make sure you get maximum benefit from your activity.

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 4 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.

The vest design of this waist trainer not only makes this more comfortable, but it also means that the waist trainer is kept firmly in place. 

There are three rows of hook and eye at the front that allow you to reduce the size of your work out waist cincher as the size of your waist reduces, or increase the level of compression.
