It depends on the insulation and conditions. Fleece-lined or lightly insulated casual pants (40-60g) provide enough warmth on their own for typical winter resort days. However, a lightweight base layer adds comfort by wicking moisture and provides a small warmth boost for colder days. Avoid thick mid-layers under casual pants—they can make the fit too tight and restrict movement. If you need significant extra warmth, consider more heavily insulated pants instead.
