Female cut of our brand new high end EcoVero  Athleisure t-shirt made for running and hanging out alike. Only a small "The Promise" pocket print. Less is more. This shirt is made from 70% EcoVero™ Viscose (derived from certified renewable wood sources) and 30% Organic Cotton. Up to 50% lower emissions & water impact than generic viscose. Also FairWear Certified, Peta approved vegan and Oeko Tex 100 standard. 

We all made a promise to ourselves. The promise to go outside and give that run the very best we can. To push ourselves beyond our previous limits. The promise to not complain until the job is done. 

Female model is 1.74 and wears Female M. This shirt turns out big. If you are caught between 2 sizes you want to take the smaller one.
