Our newly redesigned Celsius Sleeping Bag leaves ordinary rectangular bags in the rearview with a modern angled baffle pattern and a handful of anything-but-basic hues to match your personal style. But the Celsius is not just a pretty face—the double-layer construction and innovative fiber fill chase away the chill so you stay snug as a bug long after the sun goes down. The new Celsius is the same as our previous regular size (80" x 33") and features a durable polyester taffeta shell that's tough and easy to clean.
