The Jethwear Phase goggle is our bestseller among goggles and it fits perfectly for those of you with a medium to large face/helmet. With a perfect fit in our scooter helmet Jethwear Force Helmet, the glasses protect you well. With the accompanying nose guard that covers the nose well, you reduce the cold air that otherwise attacks your face. We recommend taking the face mask out of the helmet if you choose to drive with the nose guard on the goggles and vice versa if you drive with the face mask instead. This goggle comes with a photochromic lens that changes light transmission depending on UV light. Perfect for those who just want one lens from morning to night!
