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.

Although Liberty Sport sports eyewear is designed to offer the best possible protection during certain sporting activities, there is always the possibility that the wearer may sustain an eye, face, or other injury due to impact or because of the nature of the athletic activity. If the frame incurs an severe impact it must be replaced. If the frame is neglected or misused, or is worn improperly, the degree of eye protection provided may be reduced and may result in permanent eye, face, head, or other injuries. Neither the designer, manufacturer, nor Liberty Sport Inc. claims their sports eyewear is unbreakable or eliminates the possibility of injury.
