Older ones had a wool liner and dome fastners. Very 19th century. Also warm and effective but very heavy. New ones have a fleece liner and a zipper and are no longer made in Canada.
Too expensive unless you get them on sale. I have an Old 3 Star and two new 5 stars (bought on 50% off sale) . Use them as emergency overnight gear in the truck. We live n the Yukon. They are warmer than the loft indicates and easily comfortable to -30C. with good under-padding. With clothes to supplement -40C is doable.
