Some polyester like material. It's not true to size. Sizes run small.
I tried to make a return which I received help in making the return (thank you) but they only want to offer me 20% of the purchase price or exchange. So basically you are locked in to something you don't like or can't wear. I did keep the copper leather like pants. They are.
Customer service was great. I reached out and they responded within a day or two.
