Weighing a mere seven ounces and packed with 800 fill Q. Shield Down, the Mountain Hardwear Women's Ghost Whisperer Hooded Down Jacket delivers an insane warmth to weight ratio that's earned it an Editors' Choice award from Outdoor Gear Lab and Gear of the Year by National Geographic Adventurer. Perfect for alpine treks, minimalist backpacking trips, or a day of backcountry skiing, the Ghost Whisperer Hooded Down Jacket works wonders as a lightweight, yet incredibly warm midlayer. Throw it on under a waterproof shell and you're ready to rock, no matter how nasty the weather is outside. What's the secret to the jacket's minimalist weight' It took Mountain Hardwear two years to design and perfect the ultra light Whisperer 7D x 10D ripstop nylon fabric. In fact, there's only one mill in the entire world that can weave this ultra fine fabric. An incredibly laborious process, it takes approximately ten times longer to weave the Whisperer's fabric, compared to that of larger yarn size. The final product is a super light fabric that's woven very tight, making it virtually down proof to prevent clusters from escaping through tiny gaps. Keeping you nice and toasty, the jacket's 800 fill Q. Shield Down has an ultra high loft rating for tons of warmth without the heft usually associated with synthetic insulation. Knowing that down's insulating properties go out the window once it gets wet, Mountain Hardwear developed Q. Shield Down. Treated with a water resistant coating, Q. Shield Down retains its heat trapping properties in wet, soggy conditions, making it a great choice for nasty weather. Compressing to a tiny ball, the jacket's stuff sack allows you to quickly fold the jacket into its hand pocket when you're skiing or backpacking through the backcountry. The jacket also features a low profile, insulated hood and single hem cinch cord to help you seal out the cold on blustery days.
