The 3M goggles came just right, because we're in the middle of moving and the doors have to grind. The glasses fit me as well as my husband. The strap, as well as the angle of the plastic lenses can be adjusted individually and finish well, so that no sanding dust can penetrate. Ideal for use with a respirator. Most importantly it does not fog up and to be scratch-resistant according to the manufacturer. That remains to be seen. Cleaning afterwards is easy. The glasses are comfortable to wear, not suppressed and can also be used well through the tinted glasses to work outside in the summer. A protective cover in which they can be safely stowed, would have been nice and sadly lacking.
