I bought this bag about 30 - 35 years ago and have used it perhaps a dozen times. I haven't used it in recent years.
It's been stored indoors in a large bag to help preserve the down's loft. This is a 3-season bag, rated at 20 and above. I did use it once when the ambient temperature was around 20 - 25 and snow was on the ground, and it was warm and comfortable.However, this should not be thought of as a winter bag except in milder climates. The 700 fill-power goose down fill is warm and very lightweight. It can be compressed (stuffed) into a a small volume while hiking. When not being used, it should be stored uncompressed or very loosely stuffed so that the down will retain its lofting power. The shell is Gore-Tex, which has very good water- and wind-blocking properties. This increases the bag's warmth and comfort. Gore-Tex is also breathable, for comfort.
