For years, I've used Marmot exclusively for all of my down sleeping bags and jackets. Their consistent high quality, high loft and durable products are the reasons why, and this jacket is no exception.
I've taken this jacket on several backpacking trips and have not been disappointed in the least. Early evening, this jacket is all you need and when temperatures plummet at night, combine it with a good baselayer and hat and you're toasty warm. Not to mention it's extremely light weight, and stashes down into it's own pocket for packing. Oh, and it fits great underneath an outer shell or rain jacket.
Fits true to size. You won't be disappointed.
