For our hiking trips to Peru, we also added a puffy to what you are taking. Sometimes, that seemed to be the difference between sitting outside and admiring the view, and climbing into the tent and into a warm bag.

So we took a short-sleeved base layer that we almost never wore except to sleep, a lightweight hiking shirt, an alpaca hoodie sweater from Peru ($15 in the local markets), and our puffies.
