A traditional Japanese jacket/half coat. What's referred to as a hanten these days is a "wataire (stuffed) hanten" which is stuffed with cotton, mostly worn inside to protect yourself from the cold. It is worn by both men and women.
A dotera, also known as a tanzen, is a long, gown style winter garment with a low hemline, but it is often mixed up with a hanten.
A type of unstuffed jacket, that was called a shirushi-banten (印半纏, "hanten with an emblem"), is effectively the same as what is usually called a happi in the present day. There are small stylistic differences, but these were lost for the most part in the late Edo period.
