I bought every single color of these leggings. This one and the navy blue are my favorites. I bought the small size im 5' 3' and weigh about 134ish. None of these are sheer at all the only reason I can think if someone said they are sheer is because the bought the wrong size and they were too stretched out. I could see them stretching too much and being see through. I love these they aren't like tights they are warm comfy leggings. I want to buy 2 of each I love them that much. I have to say though the black pair are tighter than the rest not in a bad way they just don't fit the same as the others for being the same size.
Not sure what the other review was about but these are thick and cozy. Not thin at all. They are seamless and very stretchy which is perfect for a lounge legging. The waistband is very high and they stay put. No tugging or adjusting needed throughout the day. I've had a black pair for awhile and they wash well and have held up. I wear them several times per week. Love.
