This is how Back on track with Welltex® works
Welltex® is a yarn of polyester (PE) or polypropylene (PP) in which ceramic material is processed.
An example of ceramic material is clay or green clay.
Many ladies, but also gentlemen sometimes take a facial mask with clay in it.
In equestrian sports clay and green clay are used on the legs of a horse.
This is done to promote blood circulation, to cool or to heat, to reduce moisture and to promote recovery.
Back on Track and clay or green clay work identically. It reflects the infrared heat.
