The Mountain Hardwear Ghost Whisperer Jacket is our go-to jacket for any cold-weather activities, keeping us warm and toasty whether we're climbing at the crag or skinning our way into the mountains for some spring touring. This jacket is ridiculously light, clocking in under half a pound, but doesn't sacrifice comfort or performance in pursuit of shaving ounces. The lofty 800-fill down insulation keeps us warm on winter ski days and cool mountain camping trips, and it's protected by durable Whisper Ripstop material and a water-repellent treatment to ensure we stay warm in all conditions.
