Our 2017 Awareness T-Shirt spreads our call of action, loud and clear: Join the Fight – Defeat DIPG! In line with our mission to raise awareness of the deadliest childhood brain cancer cancer — DIPG — these shirts are in gray to represent the color of brain tumor awareness. (They are Bella V-Neck Shirts, 4.2 oz, 100% combed ringspun cotton.) The back of the shirt is the most meaningful part, though, with the names of over 350 children who have battled or are battling DIPG brain cancer. Free U.S. Shipping.
