The fibers of Thinsulateâ„¢ Insulation are fine, making them ideal for trapping insulating air and reflecting back the body’s radiant heat.

What makes Thinsulate insulation so effective? It’s all in the fibers. Insulations work in two ways: first, by trapping air. The more air trapped, the more efficient the insulation. Second, by reflecting back the body’s radiant heat.

The unique microfibers of Thinsulate insulation are about ten times smaller than the fibers of other synthetic insulations, which means they’re much more efficient at trapping air. . . and more effective at keeping you warm and comfortable. It also means more fibers can be packed into the same space, where they can reflect back more of the body’s radiant heat.
