When the girl is counting on you, you gotta keep it up... but eventually it's gonna fall down. Nike SB knows, so they've prepped this 'Hacky Sack Pack' to keep your sack on the ground at all times. Stefan Janoski and Eric Koston signature models receive embroidered uppers transplanted from that totally chill (mind numbing) university student hippie pastime and the surgery results look pretty comfy.
