They have almost four ounces of fill, so should be fairly warm. I have been surprised at the warmth of my Sam's Club EB 650 fill jacket that I picked up for $30 a few years ago to wear around town. This appears similar, but likely has more fill.
The Downlight is a lot more money, but is still cheap by down jacket standards. 5 ounces of 800 fill.
