I bought these flannel boxers for my son as he works in and out of heated and unheated buildings as an electrician...he loves these as they are warm and soft and of a top-quality material. They wash and dry with no problem.
I have bought these flannel boxers for my husband for 15 years because they are the only boxers I have found that cover the elastic, preventing the skin reaction he gets from the inside elastic on other boxers. Also they hold up really well - at least five years before the flannel wears at the top edge starting to show a thin strip of elastic!
