Hi Maria,

We appreciate your concerns about sustainabilty as that is one of our main goals to upkeep. It makes sense to scrutinize the validity of the fabric makeup. To test your concerns we cut up a shirt to do a burn test which we've sent over to you for your viewing. The tests showcases that this is a 100% cotton due to the way the material burns, the ash that was left behind, and overall aftermath as any ounce of polyester in the makeup would lead to a hard and crumbly texture (Plastic melts).

To explain the difference between the older and new shirts, this is an improved 30 singles double yarn combed cotton which means it'll go through more processing to be smoother and softer. The original shirts were a lower end carded cotton which left more impurities behind. We also had these fabrics go through a burnishing process to ensure they have an even smoother finish. We hope the explanation and video helps address your concerns as we work hard to source the proper fabrics and will never knowingly mislabel a product.

Thanks,
Kinh
