I have owned 100's of leggings over the last 20 years and these are THE BEST. Perfect compression (not tight). True to size, I ordered size SMALL ( I am size 4, 5'7, 135lbs waist -27", hips 37"). I wore these on a 30 degree morning to head out to gym and didnt feel the need to throw sweat pants over them. Well made and comfortable for my workouts.
