STORMDOWN™ POWERED BY DOWNTEK™
Keeps Down Dry When Wet
Down is nature's best insulator, but until now was susceptible to losing its insulating properties if it got wet. Accumulating moisture caused down clusters to collapse and sapped their ability to insulate. Our new StormDown powered by DownTek solves that problem. Each down cluster is treated with our durable water–repellent (DWR) finish. This prevents moisture from compromising the down's structural integrity, while preserving all of its lightweight warmth and exceptional breathability. The result is lasting loft, greater weather resistance, and reduced concern about keeping down dry in order to stay warm in wet, stormy weather.
