The timeless, classic Holbrook design was inspired by the screen heroes from the 1940s, 50s, and 60s. It epitomizes the spirit of exploration and adventure also found in pilots. Now the iconic American frame design has received a 21st century lift with the infusion of modern Oakley technology, stylish metal rivets, and Oakley icon detailing. Perfect for pilots who seek a blend of both performance and style. Holbrook’s lightweight matte brown tortoise O Matter material frame is comfortable and durable. The frame is set with classic Prizm black lenses designed to provide increased contrast, color, and detail in bright light conditions while allowing 11% light transmission. Visual clarity and accuracy are superb thanks to the patented High Definition Optics 6 base lens geometry which eliminates distortion.
