What is the temperature rating for the Culla Series?Updated a year ago

CRUA's insulated series is a unique product, due to its unique qualities and functions we are unable to measure a specific R-valve on a tent like this. Because you are dealing with air space, different climates and environments, and body heat. There isn't going to be an exact temperature rating. The way the insulation works is like the insulation in your house. In the winter your body is generating heat and heating that space. While the insulation is designed to slow the transfer of heat to the outside environment. This will also work in the summer months. You will need something like a portable AC unit or fan to cool the space. Once that space is cool the insulation slows the transfer of cool air to the outside environment. 

Please keep in mind there are a number of outside and inside factors to determine the temperature.
