The sleeping bag is very nice, I plan on using it for a Elk hunting trip to Colorado in early November. Used it a couple of times already in low 40 degree temperatures sleeping outside. I recommend putting a light blanket over top of the bag to stop the dew from soaking into the bag and getting the filling wet thus being against your skin. My only complaint about the bag is that the zipper constantly gets caught up in the fabric when you try to zip or unzip the bag and it becomes frustrating when you try to get in or out of the bag. Thought about applying water proofing to the outside of the bag to stop the dew from soaking in but I don't know if that is a good idea or not.
