I bought this hoping for something to wear in frigid prairie winters, but it's going back barely out of the package. There is NO indication on AE's site what temperatures it is suited for (and a mysterious, unexplained "2 snowflake" rating on the tag. Five minutes inside the house, and it felt no warmer than a sweater. Nylon on the inside against the body. AND it's SMALLER than a 'standard' equivalent clothing size — I could barely squeeze into it, and no blazers or sweaters are going to fit in there. (No chance to size up, either, because AE inexplicably stops their offerings at a smaller size than Penningtons, although they use the same suppliers.) The lovely colour is ALL it has going for it. Back it goes.
