Leather would be my preferred material, but the original poster specifically said he doesn't want to increase the weight perceptibly. Besides, to achieve some thermal insulation you might need at least 2 mm layer of material, and 2mm thick leather doesn't insulate that well and would increase weight.
If I was doing it for myself and wanted the solution to be as light as possible, I might use 3mm balsa layer covered with 0.4mm plywood sold to builders of model airplanes.
My own cover [for a different reader] has back made from fibreglass laminate board covered by a thin wood veneer. The lid is again fibreglass laminate with nice thick leather on the top and much thinner leather towards the display. Sides are laminated bent wood. My case more than doubles the weight of the reader, but I prefer the much increased protection and holding wood and leather in my hand when reading.
Oh ... and I would never consider 15°C to be comfortable room temperature for reading, or any other activity, besides, perhaps, ice skating or cooling down after sauna
