Hi Larry.

By this logic, we are also saying "minus Mummy", "minus Regular", and "minus Green". The dashes we have in the title is to break up the description. If you scroll down the page to the specs (which I also have attached as an image), you can see the Kelty Mistral Sleeping Bag - Mummy - 40 Degree - Regular - Green # KE45XR is rated to 40F. This means positive 40 degrees Fahrenheit. Every one of the titles for every part we carry is broken up with dashes.

Are you looking for a minus 40 degrees sleeping bag?
