The Dragon X2 Goggles are an evolution of the APX Goggles. Yes, it might be hard to imagine, because the APXs were already mind blowing. But technology does what technology wants, and keeps on moving. The X2s feature a simpler and more robust goggle locking mechanism; now you can swap lenses without taking the X2s off your face. The design of the X2s is essentially frameless, and has a super clean look. The X2s have Dragon's high-quality polycarbonate lenses that offer insane peripheral vision and distortion-free clarity. Since we live in the future, you may as well make technology work for you with the Dragon X2 Goggles.
