The ounce measurement is provided so you can judge how heavy & therefore how warm a particular batting is. Some down comforters also provide this info. Unfortunately, without knowing this same info on other brands of batting you can't make a comparison among brands, just compare within the Marshall's offerings. Same thing with the loft, the different fibers are going to have different lofts so you really can't judge... Unless you already have purchased some batting from them so you have something to compare, the info isn't very useful.
