I also have gone through a clothing crisis, living in Minnesota the temps can be unpredictable. Last week while I was out I woke with a light frost on my tent, later in the day it was 65 degrees out. I usually wear a pair of Mizuno thermo breath pants which are lightweight and warm along with a light jacket or technical running shirt, my under armour beanie also has come in handy. Most of my trips are 2-3 days so I don't need a lot of extra clothes. If it gets too cold just add a log to the fire.
