I am looking for an ultralight sleeping bag with a rating of at least 10F. The issue is that I am only 4'8" tall, and I want to get a bag that actually fits appropriately in order to maximize warmth. Some brands do have "small" or "petite" sizes, but those seem to be designed for users around 5'1" - 5'5". That range is at least 5 inches taller than me, so recommendations for petite sizes in that range won't work for me. I know that a quilt might be easier to make work for me, but I am worried about warmth. Does anyone have any recommendations for bags that go down to within a few inches of my height?
