Hard to find cotton graphic tees but these fit the bill!
"Love the patterns on Hatley’s boy tshirts, usually everywhere else sells a poly blend so was happy to find 100% cotton ones that are still fun and stylish."

Prehistoric power comes alive with this playful tee! Featuring a heathered orange body and contrasting deep blue heathered raglan sleeves, this soft cotton t-shirt is all about fun and flair. The center front graphic showcases a cartoon-style dinosaur in lighter blue, brought to life with glow-in-the-dark lightning bolt details and finished with bright yellow embroidery outlines for extra pop. Perfect for their day-to-night dino adventures!
