Old Gen, also known as OG, is a clothing brand appearing in Grand Theft Auto V.
Old Gen products can be found in Suburban, Binco, and in the Discount Store. The company sells T-shirts, sweatshirts, and caps. The logo is a lowercase "O" and "G" with a rectangular shape, similar to a flag. Examples of this clothing are the Los Santos Cap and the OG Sweatshirt.
It is a blatant parody of the real life cap company New Era Cap Company, due to the similarity of their logos and that both companies sell caps/clothes with similar characteristics.
While no known stores exist for the store, their logo appears on the back of many caps available to purchase, particularly for Franklin. Stretch and different gang members can also be found wearing OG caps/clothing. Tracey De Santa owns a pair of OG shoes as well. Curiously, this company often goes unnoticed because it does not have its own premises and there are very few places where the company logo is seen in Los Santos. The company plays no role in the storyline whatsoever.
