I have five pairs of these leggings in grey and black and find myself wearing them everywhere - running on the treadmill, shopping, working around the house. Comfortable wide waist band and stretchy material with gusseted crotch make them a delight to wear. Not see through either, they can be worn out and about. Unlike other brands, these are actually comfortable at the waist.  Washes well - I hang to dry. I wear a size medium and am 5' tall and weigh 119 pounds. Highly recommended.
