I wanted longer leggings warm enough for cooler weather. These get the job done. Comfy, warm. The ridged portion (dark grey) fits a bit more snug than the smoother material. i prefer the feel of the smoother material, but the ridged portion isn't a deal breaker. They get the job done for cooler weather (50ish degrees) and comfy. I haven't tried them in anything cooler yet because haven't had colder than 50s yet.
