This is a set of Captain Stag EVA foam mats and BUNDOK aluminum roll mats. I used them for winter camping on flat ground, and I didn't feel any cold air coming from the ground even at temperatures around 0 degrees Celsius. I no longer need them because I purchased an inflatable mat for starting hiking and camping. I will wrap them in air cap for shipping.
