Superman is usually terrified of things that glow green...but he is instantly reassured when he sees your child wearing the 50% cotton 50% polyester Superman Red/White Glow in the Dark Kids T-Shirt from fancy t-shirt makers Kids Republic! The Superman Red/White Glow in the Dark Kids T-Shirt is a heather blue t-shirt showing off a red and white worn Superman symbol; however, turn off the lights and this t-shirt will glow like a hunk of deadly, deadly kryptonite! You can just tell people that you got this t-shirt from Kevin Spacey's gift shop on Kryponite Island...before it was hucked into space.
