Spalding Galaxy Basketball
Welcome to the Space Jam. Spalding's Galaxy Basketball is an Urban Outfitters exclusive design. They say it's regulation-sized, but if you look at the photo of the guy palming the ball it definitely looks like the Pluto of basketballs. I guess it's just a weird perspective for the shot.
Or an indication that Urban Outfitters should stick to clothing and accessories, and stay away from sporting goods.
Probably the perspective thing though. Specs for the Galaxy Basketball are the standard 29.5" circumference, and a slightly heavier 24 ounces (versus NBA standard 22).
