"No room for rebellion in the Marauder. With its frameless design, exceptional peripherals, maximum venting power, and SPY's ultra-secure magnetic Deadbolt™ lens change system, this snow goggle is a reliable ally for maintaining control on the slopes. Plus, enjoy a complimentary premium bonus lens with every Marauder, making it your ultimate partner in conquering pow and ensuring clear vision during your snow adventures. Cylindrical lenses are constructed with a base curve exclusively in the X axis. In contrast, SPY's Superior Injected Curve lenses form a contoured shape, offering improved impact protection and superior optical quality.
