Yes about the eat and drink. I have a neighbor with an injured limb from a mountain climb where he didn't drink enough Surrounded by water (snow) and there wasn't fuel to melt it.

As a life-long skier, I protect from wind first. Wind will pull the heat right out of you. Wet is also at the top of the list. If you are dry and wind protected, you can survive pretty will while exercising even with modest insulation.

With that said, I just bought some neoprene gloves for dirtbiking in the winter. I am hopefully optimistic about these.
