If you love our unlined 439EB than this 439EBTL should be your choice for the fall and winter months. This style features 100 g Thinsulate™ insulation. Most of your imports only have 40 g of insulation, making this a much warmer glove. Also, most imports only use a portion of Thinsulate™ for their lining, the other portion is just fiber filler. If you want a glove with 100% 100 g of Thinsulate™ insulation, then buy Churchill.
