Using vinyl gloves under your dry gloves

[mrweekend]

While in Colorado I learned from the mountain climbers that they were using a cotton sock first, then a nylon/plastic sock then a wool sock over the top.  I've used this numerous times and have survived -40  before Gortex and the other membranes came out that allowed moisture to be trapped but air molecules to pass through.  The idea really is to create a vapor barrier next to your skin and then keep it warm. Wool loses some of it's ability to provide warmth when wet, but it's not nearly as bad as others.
The Cotton Sock was for comfort as well as soaking up the moisture.

I've never thought of applying this technique to dry gloves, but it should work rather well.  I'd personally wear a thin wool liner over the latex/gloves to warm the moisture trapped against the skin by the vapor barrier.

I'll have to give it a shot if I can get out Diving before the Iceman commeth!!
