The U.D.E.B Long Sleeve T-shirt as a 100% organic cotton shirt that has the BD, Use, Design, Engineer, Build, stamp of approval on the chest & a bigger one on the back. You can wear it when you’re off to the pub. We advise you to align the main head port by sliding your arms into the left & right limb slots. Once your hands reach the end of the limb slots & your head is through the main head port; adjust so the crew neck sits straight & that the labels are positioned at the rear of the head port, making sure that the logo is facing forwards. If the logo is not facing forward start again & repeat until correct.
