Saturdays have a sound. It's the thud of a sand-filled footbag landing on a quad. It's the call of a tailgate that started before kickoff and went later than the third quarter.
Saturday Sack is the gameday footbag built for the people who grew up doing this and the people who are about to. Sand filled, hand stitched, and tuned to the colors of the schools that own the ritual.
Footbags peaked in the nineties because they were the perfect object for waiting around with friends. They are back because that need never went away. We just got better at building them.
