When the temperatures drop drastically, I know I need to keep warm, and thermal underwear becomes my go-to solution. It is designed to provide insulation and wick away moisture, keeping me warm and dry in extreme cold conditions.

Some thermal underwear comes with temperature ratings, which I find helpful. I usually check these ratings to ensure they’re suitable for the extreme cold conditions I expect to encounter. I aim for options that are specifically designed for low temperatures.
