I've been on a couple of elk hunts and I was looking for a real puffy to add to my layering system. I have a Patagonia Nano Puffy Hoody that I've used during hunting, sometimes with a rain jacket over it to try to get warmer but it seems to me that I need a down puffy for glassing. I found a used Outdoor Research Coldfront Down Hoody for $100 and I'm wondering if that will do the trick? I tend to buy outdoor brands with earth tones. If the Coldfront doesn't work, any suggestions?
