ALPHA is an ecosystem - modular and scalable to meet the unique demands of those who face the unknown. Whether a soldier is configuring a weapon or a load carriage, versatility is key. That’s what inspired the ALPHA concept, a design that offers multiple configurations based on the mission and methods of infiltration.

ALPHA is a three-part system composed of a frame, gasket and goggle. A single lens works across all platforms.

All replacement lenses meet MIL PRF 32432 Ballistic Impact Standard, and Optical Clarity of ANSI Z87.1.
