The Rubber Band Bracelerubber wristbands for eventst trend did last long enough for several NBA players to start sporting them, though. Nike, always with a keen eye on basketball fashion improved on the trend by using the silicone rubber that they had previously used on sports watch bands and creating the Nike Baller Id Band Bracelets. Because you can"t really print on silicone, the messages were imprinted or embossed into the rubber and said sports related things like "Baller" and "Player". They came in sets three, often in specific team colors. Many NBA players, most notably LeBron James were seen wearing the Baller ID Bands on and off the court.
In 2004 Lance Armstrong and Nike, who made all of his cycling gear, teamed up and created the LiveStrong yellow bracelets which were essentially Baller ID Bands that were yellow and imprinted with "LiveStrong", the motto of Lance Armstrong"s foundation for cancer research. The bracelets are sold through Nike and Lance Armstrong"s website"s for $1 each and has raised over 28 million dollars for cancer research.
