We are happy to share with you that our Dunkleosteus and Helicoprion Youth Shirts are now available from size 2T through Youth 12. The size jump between our standard Youth 10 and Adult XS was proving to be just a little bit too wide and some of our most important fans and customers were getting left out. Not on our watch! Trilobita is already available in this size and as we continue to print new batches of the remainder of the youth line we will be filling the gap with the new size Youth 12. Please enjoy!
