That's very inexpensive for a down vest. I almost ordered one but then I notived that it looks like the baffles are swen through which would create heat loss highways.
I don't use down coats, instead I layer for insulation with an outer parka. I just retired my 60-40 parka last year that I bought in the early 1970's. I gave my down vest from the same era to my son because, like so many of my other camping clothing, it seems to shrunk.
