The Oakley Sutro Lite Prizm Matte Black have a modern design that is stunning to look at and has all the features that make it wonderful to look through. The semi-rimless design is made to increase your field of view and help ventilation so that you can cycle for longer. Another great feature that makes cycling for longer more comfortable is the O Matter frame material that is super comfortable and durable. An annoying part of sunglasses is when they slide down your nose, these sunglasses have nose pads that are designed for increased grip when you sweat so that they stay in place. These sunglasses look great and perform even better.
