Our t-shirts are made from 100% ring-spun cotton. We scoured the ends of the earth to find the softest tee for us deserving adults (well, maybe not the ends of the earth, but we did do some pretty heavy research). We think you'll be pleased. As with our baby and youth clothing, we offer an optional stitch on many of our designs that we like to call "icing." This icing, however, is calorie-free!
