Mission Bay's classic style looks great all day. The lightweight TR90 Grilamid nylon frame is engineered with comfort-fit frame geometry. AquaView advanced hydrophobic lenses repel water, cancel dust-collecting static charges, resist oily smudges and are highly scratch resistant. AquaView lenses are polarized, providing 100% UV protection and eliminating reflected glare. Typhoon's AquaView lenses are constructed from lightweight, double injected polycarbonate, a plastic so impact-resistant it exceeds the FDA's requirements by a factor of 40. Every Typhoon polarized sunglass order includes a floating optical case, a microfiber drawstring pouch (that doubles as a cleaning cloth) and a lifetime warranty against manufacturing defects.
