Most glow-printed shirts are 100% cotton; some kids' styles use a 60% cotton / 40% polyester blend.
Glow effects are applied via screen printing or glow ink within multicolor prints, typically appearing on front graphics (and sometimes on the back) in character or poster-style artwork.
Machine wash cold with like colors, wash printed pieces inside out, and tumble dry on low to help protect the print.
Common fabric names include knit and jersey, and several listings describe the fabric as a year-round construction.
Many glow shirts feature licensed fan- and movie-themed designs—character art, fan-poster visuals, and movie logos—often sold as officially licensed merchandise.
Glow effects are described as glow-in-the-dark, glow ink, or 'glowing' and are used on front graphics (sometimes larger on the back) or to highlight characters and logos.
