Sling on the Dexters Laboratory T-Shirt: Boy Genius in charcoal grey soft-style cotton — officially licensed Dexters Laboratory merchandise leaning on the show's self-styled tagline.

"Boy Genius" is the framing the title character applies to himself throughout the series, the in-show punchline that the design lifts onto the chest. The print sits as a wordmark-led graphic rather than a character portrait.

Available in a charcoal grey colourway, soft-style cotton body cut for everyday wear, short sleeves, regular unisex fit through Small to XX-Large. Pairs with denim or works under a hoodie.
