Clothes can be bought in The Stash for different prices each. They do not affect gameplay and are aesthetic only. Clothes are usually sold in sets with heads and jetpacks. Just as for jetpacks, which jetpacks are available depends on the current date, and the game cycles through all the jetpacks on an approximate 22 week basis. On the iPhone/iPod version, the set of available jetpacks may be manipulated by changing the system date and entering the game with no internet connection. They can also be acquired through the S.A.M. Prizes.
