KNOW YOUR TECH breaks down the scientific technology used in your favorite sneakers and activewear. Let’s demystify your next purchase: today’s technology is Arc'teryx Down. You're probably already familiar with goose down, the incredibly warm, soft thermal filling used in outdoor apparel. However, the performance and integrity of down filling can be rendered useless when it becomes soaked with water. Finding the right balance between waterproofing and warmth is tricky, but Arc'teryx Down's innovative construction aims to solve this problem. Arc'teryx Down was introduced as part of the brand's Fall/Winter 2013 collection and is available in parkas and zip-up jackets.

What is it? Arc'teryx Down is the same goose down filling you know and love with a few tweaks. Through Down Composite Mapping, Arc'teryx Down uses synthetic insulation in place of down filling in the areas most vulnerable to moisture, including the hood, collar, underarms, and hemlines. Meanwhile, Down Contour Construction laminates the down filling with an extra layer of Coreloft fiber fill.

How does it work? Arc'teryx Down's unique construction allows the goose down filling to remain protected and high performing even in wet conditions thanks to Down Composite Mapping and Down Contour Construction. The extra synthetic filling and layer of Coreloft fibers essentially creates a shield for the goose down.

Bottom line: Goose down is great on its own, but Arc'teryx Down is an update worth trying out.
