I have an eno ember, yes and eno underquilt say what you will, but I have loved it so much. My only modification was putting 2 parka zippers on the edges to make it a pod which has worked wonderfully, I have taken it down to the 40's with nothing else comfortably. My new challenge is that I will soon be going to college in the cold state of michigan, and I will still want to hammock camp. I want to convert my current underquilt from synthetic to down insulation, but I am rather nervous about the process. I'm confident with my sewing abilities, but down is an entirely new element for me. My main interest in doing this is to get the same packability that I have now, with a hammock pod that will go comfortably into the 20's. It's not really a matter of money, just want to reuse what I already have, and if it saves me a few $ then I'm all for it. Anyone have any experience with this? Or perhaps someone who would be willing to do the job?
