Mass drop offering Sierra Designs Elite 850 fp DriDown Parka. Too heavy?

The title says it all. It seems like it would be super warm but it weighs 19 ounces for a medium.
Any opinions? (Kind of funny asking if any WBers have any opinions. There's never been a shortage of opinions here. Kind of like asking does anybody out there breathe.)

I've had my eye on this one, some colors are on sale right now.
