Well, we could have given it a cool name but then we'd miss out on all the google searching. Our anti-condensation mat is for those people who might be camping more in the spring, fall or even winter. It's for those times when you want all the windows and entrances zipped up tight cause it's figging cold out. This mat helps to alleviate any dew that might form inside the tent on those cold nights. Fits nicely under your mattress.
