The Avalanche Slide Rx sports sunglasses seal off stray rays of light that can impede vision, but allow air to flow through the vented nose pad and across the eye to limit fog build-up. Temple tips have a 3D shape that holds the sunglass behind and below the ear, and they’re encased in TPR rubber to minimize slipping. The colors and curves of the Avalanche sports eyewear are rich and aggressive, allowing you to look nature straight in the eye.
