Oakley's distinctive 'O' logo is placed on the sides of most of their glasses and sunglasses. They also employ a unique skull logo on some of their accessories and clothing. Recently, fashion-oriented models such as the Gascan now employ a squared version of the 'O' logo. The design of both their products and their stores are a futuristic meld of organic and mechanical forms. The futuristic, spaceship-like stores make use of heavily tooled mechanical designs, such as rivets and thick metal hoses visibly connecting the store's light fixtures to a huge overhead "pipeline".

Like many high-priced brand-name accessories, Oakley's sunglasses are often counterfeited and sold in markets around the world that cater to tourists and internet buyers. Counterfeit Oakleys are often referred to as "Foakleys" (faux Oakleys) or "Joke-leys." Counterfeit Oakleys are occasionally referred to as Oakeys (pronounced: oak-E's), this is due to an inconsistency between the spelling of "Oakley," written on the bridge, on real Oakleys and fake ones.
