30 years ago , last month, I purchased a WE down bag before going to Isle Royale NP to backpack after running Grandma's marathon. My regular tent was wet and I used a double open end tarp. I thought I was going to freeze, but once I got in the bag, it was like toast. It is, I think, somewhere near the 20 degree rating and blue colored. Is this bag still good after all these years? it has lost a little down and has a few sewing patches.

i have used 30 year old down bags before.  if they are properly stored, they don't lose much if any insulating value.  if the bag spent years stored in a stuff sack, i might wonder if the loft could be compromised.  losing a few feathers here and there generally doesn't compromise their insulating value.

Its all about the loft...well actually it is a little more complicated than that...but the construction of the bag shouldn't have changed in storage. Off the top of my head I would say a bag with 2.25-2.5 inch loft would achieve a 20 degree rating.

You say it kept you toasty then ask if the bag is still good? I think you answered your own question.

Storage and keeping them clean makes all the difference. I have two bags from 1970 that I still use for loaners.
