Yes, a thermal shirt looks good with a pair of trousers or pants. You can also wear it with corduroy for added warmth. For when it gets a little too cold, the best thing to do is to layer it inside or outside with any other regular or winter clothing. The double protection goes a long way in keeping you warm and comfortable. It is also recommended while travelling, so you don’t have to rely on additional items like jackets and wraps to keep you feeling warm.
