Liberty Avalanche Upslope

The Avalanche Upslope performance lenses 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 winter sports sunglasses are rich and aggressive, giving you a colossal view that expands your horizons. The Upslope lens will fit larger faces and provides excellent light coverage from above, behind, and below. Magnetic Interchange Lens System - Switch uses high-energy magnets embedded in the lens and frame to enable users to swap lenses quickly and easily as light conditions and activities change.
