Alright I need some help trying to get worthwhile gear for when it gets cold it often doesn't drop below single digits mostly stayin around 10-30's in the winter. I get cold like noones business and I don't often sit. I'm looking for gear to predator hunt in so it can't be too bulky. Anyhow I'm looking for base layers, maybe a microfleece?? I've been told that's good for my application. Anyone got any suggestions that I can use in a pinch??
