Livestrong wristband

I bought one Livestrong wristband at Go Sport in Granada Mall, a distributor of Nike products in Saudi Arabia.

Brightly colored, rubbery wrist bands are an affordable fashion jewelry trend. But these soft bangle bracelets are a trend with a purpose. Each colored band represents a particular disease or societal concern. The hope is that people will be reminded of those issues when they see the bracelets worn. This "raised awareness" of issues can lead to increased research into cures for disease and better funding of programs designed to help those in need.

What is this Livestrong wristband?

The Livestrong wristband
The Livestrong wristband is a yellow silicone wristband (a gel bracelet) launched in May of 2004 as a fund-raising item for the Lance Armstrong Foundation, founded by cyclist and cancer survivor Lance Armstrong. The wristband itself was developed by Nike and their ad agency Wieden+Kennedy.

Purpose
The band is part of the "Wear Yellow Live Strong" educational program. The program is intended to raise money for cancer research, raise cancer awareness, and encourage people to live life to the fullest.

The band sells individually, as well as in packs of 10, 100, and 1,200 as part of an effort to raise $25 million for the Lance Armstrong Foundation in cooperation with Nike who manufactures the "live strong" bands in Austin, Texas the home of Lance Armstrong and other world wide manufacturing plants and sells the wristbands through their Nike outlets worldwide. This target was achieved within 6 months, and there have now been 70 million Livestrong bands sold to date. Individual bands sell for US$1 each.

Yellow was chosen for its importance in professional cycling, as it is the color of the yellow jersey worn by the leader of the Tour de France. Other charities were inspired by the success of the Livestrong bracelets, and many charities have developed their own wristbands for raising money and awareness.
