I just got them so I haven't had the chance to test them. Here in California I only ever deal with low temps in the 30's at night so I don't need crazy warmth.I will be putting them through their paces over Xmas in Vegas. Gets very cold on the strip at night in December. I'll report in after that.Anyone feel free to correct me but I think generally cashmere or wool will outperform silk for warmth.
