Generally, no, you don't wear regular pants over snow pants. Snow pants are designed to be an outer layer, providing protection from snow and wind.
Instead of wearing pants over snow pants, you would typically wear a base layer underneath your snow pants for added warmth and moisture-wicking. Examples of appropriate base layers include:
- Long underwear (thermal underwear)
- Fleece leggings or pants
- Moisture-wicking athletic pants (avoid cotton)
Wearing regular pants over snow pants would likely be uncomfortable and restrict your movement. Jeans, in particular, are not recommended as a base layer underneath snow pants because they are not flexible and can become stiff and uncomfortable when wet. They also don't offer any moisture-wicking properties, which can leave you feeling cold and damp.
