Now there's MagnaTech to make lens changes faster and simpler. Six magnetic points contain twelve rare earth magnets to hold the lens in place. Pull from the bottom, remove lens and bolt in a new one. Easy. Impact-resistant polycarbonate lenses are curved while they're made. So every object shows in its real location without distortion. And low-profile frames widen peripheral vision. Face foam provides warmth and comfort.
End fogging with chemically etched ICT anti-fog treatment. And venting blasts away moisture before it can settle. Two lenses-- polycarbonate on the outside and a porous acetate inner lens-- form a barrier. Cold air doesn't meet warm air from inside the goggle, preventing fogging.
