OK, on topic:
I spend a lot of time searching for and testing ice and cold weather climbing cloths. As much as I hate synthetics, some of the thinist is the warmest.
The hands are the issue, still have not found a satisfactory solution. Big John brought me some good cold weather climbing gloves similar to the cold weather ones found at Sherrill, only much cheaper. I have some very thin liners out of the ice climbing stuff that work yet begin to add a little to much.
Sorry I have not posted brands and sources, will if anyone is interested.
