Soft cotton I was excited to get this for my husband. He wears these type of underwear.
They came with a beautiful sweet letter. Now he said they felt awkward. It was like a pouch to put his manly goods in.
It separated from his body. Like a sports cup. He thought they were very comfortable.
I than washed them. No shrinking either. They did claim a cooling effect. But he had shirts that actually cool you. These underwear he claims very comfortable.
