these leg warmers are comfortable!.. not too bulky but warm..  very comfortable- they don't feel too tight (which begins to hurt or cut off circulation) or too loose (which makes them keep falling down)...  they come in great colors as well...  yesterday i even wore them under my wider leg pants and my legs were warm and you couldn't even tell i had them on...  last night was cold and i wore them to bed..  it was great!.. (yes, i took them off to shower!).. i ordered 2 more pair as i am getting more use out of them then i ever anticipated...  so worth a try!
