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."

Little shark enthusiasts will love this sporty raglan tee with eye-catching contrast sleeves. Made from gentle cotton jersey that feels soft against skin, this comfortable short-sleeve shirt features a crew neck with ribbed trim that holds up to active play. The relaxed raglan fit provides an excellent range of motion for all his summer activities, from beach trips to backyard games. Vibrant, heathered orange raglan sleeves and neckline create a striking contrast against the bright heathered turquoise blue body, while the graphic features an open jaw with embroidered teeth and a small embroidered green and orange fish for added detail. Perfect for ocean lovers who want to show off their favourite marine predator in style.
