There are a few different types of pants that can be argued to be cooler than jeans. One type is dress pants, which can come in a variety of materials such as wool, linen, or cotton. They are typically more comfortable than jeans and can be dressed up or down depending on the occasion. Another type of pant that could be considered cooler than jeans is sweatpants. Sweatpants are usually made from thinner materials such as jersey cotton, which makes them more breathable and therefore cooler to wear in warm weather. Additionally, they tend to be very comfortable and can often be found in stylish designs.
