My father is working day to day in real estate and being a landlord so he is running all of the time. He started having constant pain in the lower back so when I saw this I thought it would be the perfect gift. After a week of wearing it his back began to hurt less and each day it helps more. The quality of the material is great. He says that it is very breathable and didn't make him sweat. Overall he loved it and as a result I highly recommend it and well done to the seller!
