[M]

Product Description
It has the role of supporting the lower back muscles like corsets, so it is recommended for those who are concerned about the burden on their lower back, especially when traveling long distances. If you wrap it somewhat tight, it will show the effect well.
The main unit is very soft, so it is useful when driving for long distances or long periods of time.

Because of its high elasticity, it is possible to adjust it to one size larger for those who consider the cases that wear a thick inner layer.
