This is the first time WL Gore & Associates, Inc, makers of Gore-Tex material have shown a product made from their new lightweight Thermium insulation. It’s the new Extreme Cold Weather Boot from Belleville.
The boot features 600 grams of composite insulThe Gore Thermium is in the form of a boot insert construction, similar to the Gore-Tex membrane boot insert. However, as depicted in this graphic, the insulation is mapped, with thicker areas covering certain parts of the foot in order to ensure a better fit and protect those parts of the foot which get the coldest.
Built on the Belleville 675 platform, the boot will protect down to -20 deg F and is flight approved. In addition to the Gore Thermium Insulation, the boot also features Gore-Tex protection.
