G & F Products Deerskin Polar fleece Back and thinsulate lining Winter Outdoor Gloves

The fibers of Thinsulate insulation are very fine; therefore, they are more effective at trapping air. Since the fibers are so fine, many of them can be packed into space to reflect back more body heat. Thinsulate insulation is broken down by grams per square meter of insulation. The colder the temperature, the higher the gram insulation you’ll want. However, the higher the gram, the less flexibility you’ll have.
