I have yet another question for you experts. I have a RevX top quilt from EnLIGHTened Equipment that I can't seem to stay warm with. When I used this with my hammock, I always woke up cold during the night at 20+ degrees. This is unfortunate given the bag is for 0 degrees and I have 2oz of overstuff. This is my first down bag. The specs are 6'6", regular width, and the overstuff. I took it out last night and slept on a air mattress. I woke again feeling like I had nothing except a sheet over me. Luckily I had a -40F TNF sleeping bag that I could crawl into I have it tucked around my sides and layered up appropriately but still was cold. Is down just not my thing? Could it be a flaw in the quilt? Would hate to sell it so soon. Thanks in advance.
