RE: Secret to Keeping Warm
I usually walk between 3/4-1.5 miles in the morning before dark. To keep from sweating I pack fairly light, I wear 1 very thin wicking baselayer top and bottom. If I start to sweat I realize I'm walking to fast, I slow down a little or even break for 2 to 3 minutes. When I get to my tree I attach my climber to tree or hang on if I'm using it. Then I take about 5 minutes to "cool down" and dress with all my layers except my outer layer. Once I'm in my tree and its been 30 minutes or so, I pull over my outer layer, place 2 toe warmers in my boots, and put on my warm hat. Reverse it when I pack it out.
The only time I wear more than the thin baselayer is when it gets very cold, then I wear the next thinnest thing I got. Sure, its cold wearing a metal stand on your back when the shirt has holes in it and its 30 degrees, but I do not freeze because I sweated.
