The SI Flak 2.0 XL Thin Blue Line takes performance to the next level and brings style along for the ride.

Oakley’s partnership with our nations Law Enforcement has lasted for decades. The alliance was formed to develop new technologies that improve the safety, performance, and comfort for these brave men and women. An obsession with research and development continues to produce duty essential equipment for those whose lives depend on their gear. The Thin Blue Line collection is devoted to honoring these ambassadors of the law.

Oakley has been been toying with a mix of art and technology for some time. The idea was to create clean, authentic style for those who don’t just walk the path of life – they stomp it and leave footprints. That’s what led to Oakley Fuel Cell™. The idea here is unflinching originality and a smooth look. It’s proof that when authenticity speaks for itself, it speaks with volume.
