Can The World's Lightest Down Jacket Stand Up To Backcountry Abuse?Chris Brinlee Jr8/13/14 12:15pmFiled to: gearadventure testedreviewmountain hardwearmountain hardwear ghost whisperer down jacketdown jacketdownghost whisperertestIndefinitely Wild463EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkThe Mountain Hardwear Ghost Whisperer Down Jacket is the lightest fully featured down jacket in the world at 7 oz. It's incredibly warm and packs down smaller and lighter than four Clif Bars. AdvertisementWhat It's Supposed to Do? The $320 Ghost Whisperer Down Jacket is designed to provide maximum warmth at the minimum possible weight, while not skimping on features. It has a full front zipper, zippered handwarmer pockets, an elastic cinch for the waist, and stows away in its own pocket. And it weighs 7 oz. The GW Down Jacket is designed to be used as a standalone windproof insulating layer or as part of a layering system. How It's Supposed To Do It? There are a combination of factors at play that contribute to the Down Jacket's amazing warmth-to-weight ratio. First, its shell is made from Mountain Hardwear's revolutionary Ghost Whisperer fabric — the lightest nylon commercially available. Ghost Whisperer fabric is windproof, down-proof, and water resistant. The Down Jacket uses 800 fill power, water-resistant Q.Shield down in a low profile quilt pattern to create heat-trapping down channels for extra warmth.ShareTweet Kinja is in read-only mode.
