My go-lite quilt is my go-to for night time temperatures of 20 degrees F and warmer. I spent 6 nights in Montana with temperatures between 15 and 25 degrees in a one man tent and was comfortably warm with a base layer and stocking hat on. I am sure the quality of the down makes a difference. With a tapered pad it is a much roomier and comfortable sleeping system than a mummy or tapered bag for me.
