RE: How to prevent sweating when walking to hunting spot
Dress in layer and walk in with the minimium. Once in stand allow your self to cool down from the walk then start layer up in stages. I suffer from this problem myself and it helps a lot. I always change out my socks and bootswhen I arrive on stand as that is where I really start to feel the chill.
Don't forget to keep your mid section, head and hands warm.
Good Luck
