Eco Sportswear?

I'm currently still collating all my research in my sketchbook for my Manifesto project...I started looking at eco fashion as this was an aspect that we had to include. Whilst doing my eco research I found out that Adidas do a lot of eco stuff which I found really interesting as I love Adidas and sportswear.

They have produced a t shirt that was made out of a single piece of fabric so it reduces waste which I think is such a clever idea especially if you can get rid of unnecessary seams.
