This large custom wool sleep sack is 42 inches long, my five-year-old can easily fit in it. The bottom edge is 20 inches across, and the top edge about 9 inches across. Amazingly I used only one sweater for the inside lining, a cream-colored XL men's soft merino wool sweater. The outside is patchworked solid colors. They are all pretty thick with a variety of textures. The closures are snaps all up the front, per customer request. Top ribbing is a soft red wool/angora blend.
