This is a new winter knit hat in basic black. If you don't know what color someone likes, you can't go wrong with the color black. It is one size. It is a stretch beanie style. This is a large open knit had which means it will stretch. Please note although I am listing winter hats as a man's hat, anyone can wear them. If you are interested in several of my hats, please bundle them as I would like to save you money on shipping.
