Thanks for the kind words. It took me a long time to make and about $200
I forgot to mention that the inside is not Pertex GL, it's from ti goat, old 7D which is lighter, and my zipper is the same length as zpacks, just on the bottom 3/4. My goal was to make a knock off ZP sleeping bag without a closed foot box. I planned on using less down but added more to make the loft amazing like a Katabatic quilt.
