I wear much more clothes, pants and shoes than others. Why do I catch a cold when the weather is cold?

You'd better check your rhinitis or something. Sometimes it's a symptom of rhinitis, which makes you feel like a cold. Especially in cold weather, it is very normal to induce rhinitis. Exercise is only one aspect, and you can also look at something like grape seed extract to enhance immunity or anti-allergy. In addition, I suggest you go to the hospital for an allergen test. You may not know it yourself, but it may be an allergy to down or something, and it is also a symptom of a cold.
