I have seen where any people complained that the thermals were too thin...and they are not..think about it..you wear them under pants, skirts, jeans..how bulky do you want to be? When dressing for a normal day..these are great..if they were thick..you would be very uncomfortable..in your tights, with jeans, pants, skirts, dresses......you can wear these under hose, tights, or over them too.....and be VERY extra warm!
