The STX Rookie goggles are smaller than the 4Sight and designed for a younger player. The oval wire design enables superior visibility and the vented silicone padding does not absorb sweat or moisture, which minimizes breakouts and makes the goggle easy to clean. The cage is made of steel. This goggle meets ASTM F3077 requirements for women's lacrosse and ASTM F2713 requirements for field hockey.
