Our 2018 Awareness T-Shirt emphasizes that it is only if we all join forces that we will overcome DIPG: Together We Will 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 400 children who have battled or are battling DIPG brain cancer. Free U.S. Shipping.
