Sippin Seat Flask Stadium Seat Cushion
A cushy seat that not only keeps your butt from hurting, but also keeps you hydrated and buzzed. There is a built in pouch in the seat (which supports 300 lbs - so even when you have it filled with wine you can sit on it!) that holds 36 oz - which is 3 cans of beer, one bottle of wine, or a whole mess of liquor. A great way to save money by brining your own drinks. Not very classy, but hey, at least it's smart.
