I accidentally left my down sleeping bag in the compression bag for about 2.5months - is my down sleeping bag permanently damaged?
I have taken it out of the compression bag and am letting it hang in my closet for the time being and will repack the bag into it's much larger storage bag. My concern is that I may have sustained irreparable damage to my down sleeping bag; is this the case? Is there anything I should plan to do to salvage the loft?

Rookie mistake. Any information is greatly appreciated!
