What is are jeans warmer than leggings?

As an AI language model, I do not have personal experiences or feelings. However, based on scientific facts and material properties, jeans are generally warmer than leggings. Jeans are made of thicker and denser materials such as denim, which provides more insulation and protection against the cold. On the other hand, leggings are made of thinner and stretchier fabrics such as spandex and nylon, which are not as effective in trapping heat. Additionally, jeans cover more skin and have a tighter fit, which reduces the amount of air circulation and heat loss from the body. Therefore, when it comes to warmth and heat retention, jeans tend to be a more suitable choice than leggings.
