Thin, warm, light
What makes Thinsulateâ„¢ Insulation so important to a cold-weather boot? Three words: thin, warm, light.
The image above is a comparison of heat loss. The boot insulated with foam is losing more body heat than the boot insulated with the Thinsulateâ„¢ Ultra Insulation Extreme Performance for Footwear construction. High areas of heat loss are indicated in red and white. Low heat loss is shown in blue and green.
