One of America's oldest denim makers, Levi will soon introduce their new Eco line. A collection of blue jeans made with 20% 12 to 20 oz. of recycled plastic bottles(per pair). It'll include styles like the 504 straight fit, 511 skinny jeans and their classic jackets.
You can expect to see them in retail stores in January 2013.
I'm assuming they are wrinkle-free. I can't imagine ironing a pair with all that plastic.
