Several years ago Sierra Designs reissued their 60/40 parka on a limited basis. I don't think they sold well as eventually the excess wound up at Sierra Trading Post. I'm not aware of anyone making anything out of 60/40 (or 65/35 the better of the two fabrics) any longer.

I'm a thrift store junkie and find these with some regularity for very little money. I've worn and bought and sold several over the years. My current favorite is by Alpine Designs. My all time favorite was by Class 5 Mountaineering Equipage, but it was just too large for me and I sold it on ebay.
