Most of the world will be focused on the runner’s speed at the Olympic Marathon on Sunday, but when you catch a glimpse of Kenya’s Abel Kirui, check out his uniform.

According to a report on the Sustainable Oregon Web site, the world champion’s singlet, made by Nike, was dyed without the use of water.

The normal textile dying process uses between 100 and 150 liters of water just to process a single kilogram of textile materials.

Overall, this consumes a total of 2.4 trillion gallons of water, which equates to filling 3.7 competition swimming pools.

The company that makes the new singlets, DyeCoo, employs a process that uses fluid carbon dioxide to dye fabric.

According to a Nike press release, the result is a dyeing process that is not only waterless, but also produces as much as 60 percent fewer carbon emissions than conventional methods.

Even better for the environment: the materials used for the singlet comes from recycled plastic bottles.
