Everything a google should be. Comfortable, good peripheral vision, great anti fog, easy lens swap system, many variations in size color, lenses choice. I really like the beveled nose bridge foam. It allows for a larger lens that goes further down your face without sacrificing nose room so your airway won't be squeezed close.
Best of all is the price. Its the best deal out there and the best google out there, and you get a low light lens in addition to your standard lens.
