How many times have you been on a long road trip and that last soda knocks on your bladder walls and wants to leave? Now! Damn! But it’s very late, or you’re stuck in traffic, or it’s raining to beat the band. You could just relieve yourself in the car.
Check out the RoadBag. Specifically designed for your manly junk you just (“scuse me while I whip dis out!”) pee into this handy disposable pee sack and continue on your way.
Or you could cut a hole in your floorboard and use a funnel and tubing to do it on the road.
