This is my first post and I hope its not too off topic for the is forum. I recently purchased a recon 3 sleeping bag and I am wondering if anyone out there has one and if so when its not stuffed tightly in its sack should I leave it out? Meaning I was told by someone once that sleeping bags kept in their stuff sacks loose warmth due to insulation binding up from being tightly packed all the time. Does anyone know about this? Thanks in advance if you took the time to read this.
