The material seems solid. The chamois is definitely nicer than comparable bins at the same price. Overall I really like these except….the leg openings. They fit great but the leg openings cut off circulation. I tried thinking they would stretch out a bit but they didn’t. I had to buy a size up. I don’t have them yet to try. Read the return and exchange policy carefully so you don’t have to buy two pairs. Overall, I like them. Just a size conflict is all.
