This set of three Knocker boxer shorts are made from polyester and cotton, making them machine washable and suitable for all seasons. The shorts come in a plaid pattern with multiple colours that are perfect for men's underwear. With a size of XL, they are perfect for men who want to feel comfortable but still fashionable. These trendy shorts don't compromise on style and are ideal for any man looking for a set of underwear that is versatile and easy to maintain. I've worn mine for years and they've held up well.  I just outgrew this size.
