I recently purchased 3 pair of thermal underwear from Walmart. One white, one black and one gray. I have had stitching/seam issues with all 3 pair in crotch area and knee area. The complaint is made worse by the fact that each pair were worn 1-3 days in a row and each washed once. When I went to wear the second time is when I noticed issues so I looked at the other 2 pairs, they also had issues with the seam stitching coming apart. I am extremely disappointed and upset. I live in Chicago where it gets very cold and I have no long underwear to wear. I have no receipt so I am unable to return to the retailer. I am not sure of your solving product issues policies but I would appreciate some sort of compensation which will allow me to have the 3 pair replaced.
