Celsius vs. Fahrenheit: What’s the Difference Between These Sleeping Bags?Updated 7 months ago

The main difference between the Celsius and Fahrenheit sleeping bags is the liner material. The Celsius bags have a poly-flannel liner, while the Fahrenheit bags feature a cotton-flannel liner.

However, please note that there are two versions of the Celsius Sleeping Bag: the upgraded model and the original model. Both are named "Celsius Sleeping Bag," but they differ in zipper design. The upgraded Celsius bags have an "L-shaped" zipper that runs along the bottom and right-hand side, allowing the bag to be fully opened and used as a blanket. The older model has an "I-shaped" zipper, meaning it features a zipper on either the left or right side, depending on which sleeping bag you order.
