The Proto Switch™ Axis™ Pro Goggle system is the premier goggle in the Switch™ line. Boasting soft compression formed earpieces, resulting in a lighter goggle. The patent pending 1/4 turn snap lock system is fast and secure, making lens changing simple. The outer frame holds the lens in place with no extruding edge or protruding tabs; just clean looking style. The inner frame structure of the Proto Switch Axis goggle provides a secure platform for the lens and frame to compress together, giving stability under the most severe of impacts. The split frame and lens is secured in place by right and left locking tabs. Once assembled, the split frame system holds your lens securely into place while providing comfort and style. The patent pending locking tabs allow you to change lenses in seconds. The Proto Switch™ Axis™ Pro Goggle System comes standard with a clear tirodial thermal lens and a co-molded combination density mask for flex under play. The multi-ported earpiece allows unrestricted audible transfer to take place without sacrificing any ear protection and provides total comfort with two-layer foam.
