Nose clip works well, mask seems to fit tightly.
Wear most often when working construction with Habitat for Humanity.  I wear eyeglasses and have difficulty with fogging.  Nose clip seems to help keep the stream of warm air off my glasses--I also tape the top to my nose.  The clip to adjust the straps is a little stiff, but preferable to the elastic bands around my ears.  Good product overall.
