The secret to keeping the outer extremities warm is to maintain/boost your body's core temp. When your core starts to get cold the body shuts off circulation to the extremities to keep vital organs warm. Basic stuff, right?? Well have the missus sew a few pockets into one of your bottom layers and put those chemical warmers in those pockets. I have a shirt with pockets sewn on the back of my neck, under the arms and at the base of my back...I'm telling ya, this works slick.I saw a show 'survivor man' or something similar on Discover Times. He had on a heated vest with no gloves on and they dropped the temp to 0*F. His hands did not get cold and he maintained dexterity in his fingers, they shut the vest off and almost immediately his fingers got cold and he lost his dexterity.Give it a shot, works for me.
I JUST USE SOCK LINERS, WOOL SOCKS AND A PAIR OF ROCKY'S 1000 GRAM THINSULATE
what seems to be the best blend for sock liners?
Polypropylene."Polypropylene is not a dyed fabric. The color is built into the fabric so you won't have any bleeding or fading. Polypro keeps feet warm and dry. Polypropylene is a synthetic fabric that does not absorb any water making it hydrophobic. The fabric speads water evenly across the feet allowing the fabric to dry quickly."
