Celebrate Saint Patrick's Day with the best we have to offer. The Grateful Dead Shamrock long sleeve tie dye happens to be my favorite t-shirt and it's 100% cotton, hand printed, hand dyed and built to last!!! Our St. Patrick's Day tee shirts, hats and hoodies are great for March 17th or any other time of year... Each of our Jam Band tee shirts is an original piece of handcrafted wearable art, officially licensed and made in the U.S.A.
