It was rated to minus 20 and I have used it at -10 so I can verify the rated temp is accurate. Please note that this was the most expensive top of the line bag that I could find in the early 70's.
Todays market it would be a 600.00 to 700.00 bag. It was and probably still is the best. I do know that this bag was rarely used and considering its age is in good condition. Lightly used over the years and well taken care of.
There are some small marks highlighted in the photos. Please see pictures > Actual item pictured > No original stuff sack.
