I, too own a piece of Montbell down apparel, but in my case it's the Ex Lite sweater which is designed for somewhat milder temps than 25 degrees. I can say that it is a well-made piece of clothing and was well-priced in comparison to its competition. I am quite happy with it. (Oh, and Montbell sizes run just a tad snug in my experience.)

Unfortunately, I know nothing about the Montane item being inquired about and can say nothing useful in regard to it.
