In a statement on their Instagram, Phenomenal said: "Millions of protesters across the country are speaking out against anti-black racism and police violence."
"But we still have a lot of work to do, and we can't let up. So keep going. Continue fighting for our Phenomenally Black community until there's full accountability."
All proceeds from the t-shirt will go straight to the Black Futures Lab, a non-profit organisation that was founded by Alicia Garza, a co-founder of Black Lives Matter. The Black Futures Lab aims to amplify political power locally, statewide and nationally, for the Black community.
