Weighing in at a mere seven ounces, Mountain Hardwear's Ghost Whisperer Hooded Down Jacket is a weight saving addition to your backpacking kit. The lightest down jacket on the market, it's packed with 800-fill Nikwax treated hydrophobic down. You won't need to worry if the jacket gets wet in a light rainstorm while you're out in the backcountry or in an alpine environment as water will shear right off. With a low profile slim fit shape, the Ghost Whisperer makes a great layering piece to wear under a shell jacket when skiing or it can even be worn as its own layer and works great with a harness. The down insulation is packable as well and the jacket can be stuffed into its own pocket for easy storage. A carabiner loop adds convenience and clips onto a pack or harness while it's stuffed away into its storage pocket.
