Nice shirt, but colors are off

I wasn't sure if the yellow would look more like the deeper yellow or the paler yellow in the photo with the girl wearing aviator goggles. Turns out it's more like the paler yellow. You guys should fix the other photo. Other than that, the shirt is nice.

Thanks Emma, and sorry for the confusion, we appreciate your feedback about the photo. We'll fix it.


I bought this for my four year old who loves whipping his scooter around the park. The colors are vibrant and look great. Fun store, will be back

My kid loves it

What an awesome shirt! My boy loves it and wants to wear it to school, to sleep, then to school again haha. He doesn't want to take it off

A bright little girl, whose parents surrounded her with STEM and meaningful ideas, blue-sky daydreams about math, friendship, music, art, science, and fun
