Lightweight, fast-drying, and built for nonstop kids—this youth long sleeve brings athletic performance together with a bold lung “superhero poster” graphic that makes science look cool. The moisture-wicking polyester keeps them comfortable through PE, practice, recess, and weekend adventures, while the vivid print adds just the right amount of personality (and a subtle reminder that lungs are kind of a big deal).

Designed with an athletic fit for easy movement and layering, it works on its own or under a hoodie when temps drop. Finished with a tear-away label so nothing scratchy ruins the mission.
