Silk and shirts are nice and not bulky. You
can also get socks but I have not work the socks. I have been wearing my
army socks which are mostly wool. If one has sweaty feet they will be
colder due to perpiration and you might need to change your socks every few
hours. Sounds like the 'electric' socks might be nice
though. The darn cold weather really slows me down unfortunately.
A note about cold and sensations is that early
frost bite can give you the feeling you are warm but you are probably getting
some tissue damage. Mary Ann
