Breeches, jodhpurs, and tights are all types of riding pants, and you can choose whatever type of riding pants you find most comfortable and suit your preferred riding style. Modern jodhpurs and tights have become more like a regular gym pant, so are thin and comfortable, but if you prefer to wear jeans, riding jeans will ensure you stay comfortable in the saddle.
Breeches are a traditional form of riding pants made with flexible and stretchy fabric with a zip closure at the top and full seat protection. Breeches come in all colors and styles with all the different rises, so choose whatever you find most comfortable to wear in your normal pants.
