The inside fleece is a nice touch.  I bought these to wear under my jeans when motorcyle riding, to add some extra warmth.  However, like most "stretch" pants/shorts/leggings these days, the waist is very loose which must be made for a "growing" customer base.  Although I am by no means model thin, if I wear these by themselves I have to constantly pull them up as they keep sliding down.  When layered under other pants they should stay up.  Also, the outside fabric is not your typical legging material -- it's a slicker, shinier stuff which you may or may not like depending on how you will use them.
