I think they would be a perfect fit for November/December. I used them exclusively on a high mountain snowy New Mexico hunt in December and they performed in a wide range of conditions and physical exertion. Block the wind well, held up to light and heavy snow, kept me warm as I sat in the snow against a log and waited on a bull to step out from the timber for nearly 2 hours, and when on the move they dumped excess heat well from the hip vents. I’d say from mid October on they are about the best pant on the market. Sitka timberlines would be my second choice.
