We have partnered with Soft Goods to bring you the highest quality and heaviest t-shirt on the market made from 100% US grown cotton that is custom cut, sewn and dyed right in our hometown of Detroit MI. At 9oz per square yard (305 GSM) this tee is as tough the city where it's made. Each piece is custom dyed with an added enzyme treatment to further the softness. We also teamed up with local Detroit artist and sign painter Kelly Golden to create the the back graphic that speaks to not only this collection but also to StockX as a whole. Built In Detroit Verified Worldwide! The finishing touch is a tasteful embroidered homage to our authentication tag on the chest.
