TYR Pro Nano Metallized Goggles The Nest Pro™ Nano Metallized Goggles are performance goggles that transcend traditional design. Inspired by the unique bird nest architectural design of The Beijing Olympics' main stadium, the structural elements of the LGNSTNM Nest Pro's™ frame creates a unique grid-like effect, similar to the way a bird's nest is intertwined for support. Metallized lenses reflect light & reduce glare, providing excellent peripheral vision, while anti-fog, construction enhances protection. Showcasing the same performance features in a smaller, compact size, The Nest Pro™ Nano Metallized Goggles provide leak-free use & a wide viewing area for light absorption and increased range. An ideal goggle choice for performance, training, open water & triathlon applications.
