Out of the big brands, the smallest stuffed sized zero-degree sleeping bag I have found is Marmot's Lithium (7.5x15), followed by Feathered Friend's zero-series (9x15).

Nunatak sells a +5 quilt, the Arc Expedition which packs 7x14 in a small or 7x16 in a medium.

Keep in mind that all of these high-end zero degree bags will set you back $500+ at full-retail.
