From the page on Clark's website for the Z-Liner 270...
What are they trying to say here (bolded text)?A typical camper using a high quality sleeping bag can sleep in this model down to approximately 32 F (0 C) without adding insulation and down to approximately 55 F (13 C) without adding insulation. The addition of the Z-Liner will allow you to sleep down to at least 20 F (-6 C). This is a conservative estimate. Many customers report sleeping comfortably into single digits Farenheit when also using a high quality sleeping bag.
No sleeping bag = 55F
Sleeping bag = 32F
Add the Z-liner = 20F
Z-Liner + sleeping bag = below 10F possibly
Am I getting this right?
