I bought these for my husband who is very slender.  He always wears baggy cotton boxers but I wanted to see him in something different.  I usually get him a size 16 in boxers but thought one size up would be best for a cotton knit.  They are well made and fit him perfectly.  He likes them and wears them.  Our 25-year-old son, who is a little bigger, likes to borrow them.  I think they are the perfect hybrid of a boxer and a brief.
