Mongolia often calls itself the ‘Felt Nation’ and this fitting tribute only touches on the importance this material has held to the people. Its versatility, warmth and strength means it can be found as boots, hats, gloves, a cover for the car engine, a bag, a rug and much more. Yet its most important contribution has been to provide simple and effective insulation to the traditional tent (ger). This goes around and over the wooden ger frame as large rolled felt pieces and the whole is then usually covered with a fitted white cotton cover. These felt pieces are made approximately 2cm thick. While in summer one layer is enough for the tent, in winter (as temperatures drop to minus 40 degrees C) it is more common to use 3 or 4 layers.
