Video from Oakley Military showing the 2016 offering from Oakley Standard Issue (SI)... "Available in Spring 2016, the Alpha™ Eco-System allows multiple configurations based on mission profile and method of infiltration. The Alpha™ Eco-System consists of three parts: the SI Ballistic M Frame® Alpha™, SI Ballistic Halo™ Goggle and the Helo Gasket with a single lens working across all platforms.

The Ballistic M Frame® optimizes the most crucial elements of performance with flush-mount surfaces to help prevent fog buildup. The SI Helo-Alpha™ Gasket is a lightweight rubber component designed for rapid deployment in situations of sudden high wind or dust. The SI Ballistic Halo™ Goggle is specifically engineered to optimize the two things that matter most in eye protection: a comfortable fit and equipment compatibility. It comes with multiple strap options including a split strap, full strap and rail strap adapter. The SI Ballistic Halo™ Goggle is also compatible with all helmet and O2 mask systems."
