This officially licensed Marvel Spider‑Man notch‑collar pajama set is crafted from a milky jersey that’s silky soft, lightweight, and breathable. The notch collar gives it a subtle vintage look, while the top and coordinating shorts display a bold web and Spider‑Man all over print. Key features include a stretchy knit for ease of movement, elastic waistband on the shorts, and tagless or flat seams for comfort. Pair it with Spider-Man slippers and a favorite comic book for the ultimate superhero sleepover. Fabric and fit are important safety considerations for children’s sleepwear. Sleepwear should be flame resistant or snug-fitting to meet U.S. Consumer Product Safety Commission sleepwear requirements.
