relieved tremendously the lumbar spine and the connective tissue in the abdominal area. The inside is soft and worked the outside at the back with breathable mesh fabric and unyielding reinforcing struts. The hook and loop fasteners are infinitely adjustable to allow a perfect support function from below and from above an ideal stabilization. Washed I have not yet because I had recently ordered and got already delivered two days later, but if a supplement has been possible, I will report. Also on the actual breathability that so far I could test only conditionally.
