Kenyan marathoner Abel Kirui will run for the gold medal in London on Sunday wearing a Nike Inc.-made singlet that was dyed in his nation's colors without the use of water.

The uniform marks the first results from Nike's investment in DyeCoo Textile Systems Inc.

The Washington County sporting goods giant in February announced it had invested an undisclosed amount in the Dutch company, which has developed and built the first commercially available textile dyeing machines.

Typically, textile dyeing uses between 100 and 150 liters of water just to process a single kilogram of textile material, and the synthetic textile dyeing industry uses 2.4 trillion gallons of water per year. That's enough to fill 3.7 million competition swimming pools, Nike said.
