The multi-based Mosaic lens helps to maximize direct line-of-sight and peripheral vision, with a natural curvature providing comfort, protection and unencumbered vision on the slopes. The unit's "Grilamid" hinge system allows the goggles to be quickly flipped up onto a rider's helmet without the need of any additional adjustment, while the quick-releasing "Hytrel" lens bracket system makes for quick cleaning and adjustment on the fly. The Mosaic lens also features an anti-fog/anti-scratch coating for prolonged life and high performance, with 100% ultraviolet ray protection minimizing the risk of serious sun damage. The facial contact point of the goggles is fitted with a triple-layer fabric called "Isotron" foam for warmth and comfort, with a moisture-wicking fleece composite called "Dri-Force" promoting consistent dryness. In addition, the Apollo includes a dually-adjustable silicone-ribbed strap that ensures a safe and reliable fit while skiing or snowboarding.
