I've pretty much read all the forums I can find on these bags along with a few YouTube videos but wanted to see if anyone here has had experience with them so I can ask a few direct question. How has it held up over time? Does the warmth of the bag differ that much from when it was new (apparently a synthetic issue)? Currently using a M1949 which I've had for over 30 years, would a Superlite or Ultralight be the equivalent in terms of insulating? Have a few more questions but I'll wait until I get some feedback. Any help would be appreciated, thanks.
