I have been using this type of goggle for 12 years, wearing them everyday outdoors, in vehicles, and in buildings with noticeable air movement. Those goggles I found at various hardware stores and on the internet, and they worked but were not flexible enough to make as good a seal around my eyes as I would have liked, although I could tighten them, but then they dug more into my forehead and cheeks. The CG2 goggles work much better for me than any previous goggles, since they are made of a more flexible substance and seal better around my eyes. They also dig into my forehead and cheeks much less so are more comfortable to wear. Sometimes I need to check to see if I am wearing them or not!
