I hate to let these go, but I'm getting hitched and my freedom has to be taken away from me. Well, not entirely true. I just won't be hitting temps anywhere near that for quite awhile. Both quilts have 4oz of overfill in them and are made with 900 fill down and M50 fabric. The fabric is wind resistant and works very well in the cold. "Pockets" has used it in 20f with proper venting and had a nice snooze in her hammock as well. Both stored hung up in a closet and smell nice too. The Incubator has one tiny hole in it that is sealed up with cuben tape and no down has leaked at all since I put that on there. Pictures are below. Incubator $260 shipped (US) Burrow $250 shipped $500 shipped for both. If you have any questions than please send me a Pm. Thanks a bunch. Fronkey
