Oakley SI M Frame 2.0
Oakley SI Ballistic M Frame 2.0 Sunglasses
Introduced in 2006, the tough Oakley SI Ballistic M Frame 2.0 Tactical Sunglasses were designed more for battle than for beauty. The most obvious change from the regular M Frame is the thicker, more rugged frame. The wide elbows past the temple hinge were brought in to better accommodate helmets or other headgear, but the temples also became stronger, opting for a more vertical profile. The ridges not only enhance the overall integrity, but also lend a bit of styling to the rugged frame.
The Ballistic 2.0 lenses, made of pure Plutonite, are a tad thicker, as you might expect given the MIL-PRF 31013 rating. As if Oakley’s genius wasn’t already on full display here, their patented DedBolt clip was designed to literally lock in the ballistic lens to prevent separation during impact.
Oakley SI Ballistic M Frame 2.0 Tactical Sunglasses exceed ANSI Z87.1 Industrial Standards for high-mass and high-velocity impact protection, and are stamped for industrial and military safety compliance. The Z87.1 stamp can be found near the top edge of the lens above the nose bridge, hidden by the brow of the frame.
