This wild slumber sack is covered in zebra-print fleece, lined in hot pink satin and features a black zipper. Opened, it measures 56" x 68". Closed, it measures 28" x 56". The manufacturer is formerly known as “Woogies.” These high-priced bags were a surprise hit in 2005 for Greg Bonner, 20-year owner of the 40-year-old Heights Toy Center in Little Rock, Ark.
