During the cold time of year, sweatpants alone often aren't enough, so wear a pair of thermals underneath and feel as comfortable as sitting in a Swiss ski chalet during a blizzard! Friendly advice: wear something form fitting underneath the thermals, like briefs and you'll be more supported. Wool is good at keeping your body temperature from dropping, but can make some sensitive parts uncomfortable, so having even a small layer between the two helps. Other than that, brilliant product!
