Don’t underestimate how much body heat you give off hiking up the side of a mountain! Easy to put clothes on During your hike, not so easy getting dry and staying warm if you get all sweated up. I’ve made that mistake all too many times.I'm gearing up for tomorrow. Going to be a cold one for sure. I have very high hopes for tomorrow morning. Long steep hike ahead of me to get to the bench I want to sit on. Good thing it's going to be so cold, otherwise I would never make it up there without sweating to death. Normally I would wear thin leggings and a thin top for the hike but its going to be too cold for that.
