What is DownTek™? Here’s the thing: Down is the single best insulation that exists. Period.
Its Achilles heel? Water. Rain. Sweat. Snow. Anything wet. Mother Nature designed down clusters to trap pockets of air. Those pockets insulate, keeping you warm and comfortable. Unless they get wet. Then, those air-trapping pockets deflate and lose their ability to insulate.
Enter DownTek™—Insulation with Loftier Aspirations. It shields insulating air-trapping down clusters from all wet things. It’s the most amazing thing since the umbrella.
