This collaborative long-sleeve t-shirt features a bold, oversized 3D-rendered SpongeBob SquarePants graphic on the back—depicted mid-laugh with tongue out and arms raised—creating a playful, high-impact streetwear statement. Below the character, 'CASTELLI' appears in yellow sans-serif font with pink underline, directly above Supreme’s iconic green-box logo. The garment is constructed from premium cotton jersey for softness and breathability, with ribbed cuffs and hem for a clean finish. Both sleeves are densely decorated with repeating branded patches: Castelli’s red scorpion logo, Supreme’s box logo, SpongeBob-themed graphics (including Gary the Snail and 'SpongeBob SquarePants' text), and other collab motifs like 'ROSO' and 'ISO'. A small red Castelli scorpion logo also sits at the upper back neckline. Designed for maximum visual impact, this piece merges high-performance cycling heritage (Castelli) with streetwear authority (Supreme) and pop-culture nostalgia (Nickelodeon). Ideal for layering or standalone wear in casual urban settings, it appeals to collectors, hypebeasts, and fans of ironic luxury mashups. Fits true to size with a relaxed silhouette, suitable for spring through fall.
