These limited edition t-shirts are only available through the Biltwell web store. We donate 100% of all proceeds from every shirt to our friends at the Warrior Built Foundation. 100% pre-shrunk 4.1 oz cotton tee is detailed with hand-screened water-based inks, woven clip tags and the irritating collar tag has been replaced by a screen-printed label. Original artwork by our friend Aaron Mason at . These premium, USA-made blanks are the same Soffe brand green t-shirts that are issued to US Marines. Thin, breathable and super comfortable but not a slim-fit style.
