Our First Ascent guide team built this ultralight jacket for alpine climbing in cool to cold weather. Windproof shell is recycled ripstop polyester with a StormRepel® durable water-repellent (DWR) finish. Super high-loft 800 fill StormDown™ powered by DownTek™ sets a new standard for moisture-resistant down. Each cluster is treated with a DWR finish so the down retains its loft and superior insulating properties even in wet conditions. We performed extensive tests to determine the best DWR down available, and the DownTek™ technology is clearly superior.
Active: Our most athletic fit. Close to the body without restricting mobility. Designed to fit over baselayers and lighweight midlayers.
STORMDOWN™ POWERED BY DOWNTEK™
Keeps Down Dry In Wet Weather
Down is nature's best insulator, but until now dampness rendered it ineffective. Our StormDown™, powered by DownTek™, treats each down cluster with a durable water-repellent (DWR) finish, to prevent internal moisture accumulation and preserve down's structural integrity, lightweight warmth, and exceptional breathability.
"It's made specifically to be a very lightweight layer with down. That makes it lighter than with any other kind of insulation, very compact, and packable. When you wear it, you hardly know you have it on."
