Introducing our "Upgrades" long-sleeved tee, a symbol of resilience and strength for children who've bravely faced congenital heart defects and undergone life-changing surgeries. This tee is a testament to the courage and tenacity of every heart warrior, and features a vibrant, mechanical-style heart composed of wires, metal plates, and screws to emphasize that not all heroes wear capes. Wear your story with pride, inspiring others with the message that no matter what challenges you've faced, you've emerged stronger and more extraordinary than ever.
