PSD collaborates with Hey Arnold. For the Gerald 33 boyshort underwear in a red colorway. The boyshorts take on a sublimated graphic to replicate the look of mesh basketball shorts, while the number 33 and Arnold's best friend Gerald can be seen along the sides. Made from polyester stretch fabric that wicks moisture, the form-fitting boyshorts feature a full coverage construction, flat-lock seams, and a tagless waistband design to eliminate irritation.
