If they can't be worn without a long top that covers a child's bottom, then I don't think they can be called 'leggings' or 'pants'. In fact, these are very thick tights. I returned them as they were not what we were looking for and my daughter did not find them comfortable. However, if you are looking for tights, they are very thick and I think they will be very warm.
