I am planing an AT nobo thru hike starting this March. I'm thinking about getting the Mountain Hardwear Ghost Whisper Hooded Down Jacket for the trail. Does anyone have any experience with, or opinions on this jacket? It's 850 fill and 7.5 oz which is good because weight is always a concern. I tend to get cold relatively easily so I want something nice and warm. I will be layering up and will have a shell for wet weather conditions. Alternate suggestions welcomed.
