Janx Outerwear was a business in the Ferengi Alliance in the 24th century.
In 2376, developers at Sorv Spacesuits 'N' Things created a state-of-the-art bog suit, which was capable of operating in the densest swamps, and also included camouflage and DNA masking technology. The design of this suit was then stolen by Janx Outerwear, with the help of a Sorv insider. When that insider demanded more money from Janx to keep quiet about the theft, and Janx responded by hiring Eliminator Leck to kill him. Janx gave Leck one of these bog suits as payment.
