I have be given a old ( 3 years old-old) nanok down sleeping bag comfort rating -5 but I am a little sceptical that it really would be any good at that temp.
Also there appears to be a lot of down pokeing out at the seems and when I tested it out in the living room I found a bit of down scattered over the floor, is this noraml of a down bag and is there any thing i can do to stop the feathers escaping through the seems?
Thanks in advance and MERRY CHRISTMAS.

Every down item I've ever had has lost down to one degree or another. Might be worth a real close look over and check a seam hasn't split, etc. Is it possible to check the original weight to see if its lost a noticeable amount of filling.
