You just need to find a toilet when your tank is full. Yeah, for guys, we can always find the tree or some hidden area, but for girls will have harder time. Alright, today we are talking about the TravelJohn Disposable Urinals. Just shoot your urine into the pouch and it will instantly turn into a gel then toss it in nearest trash can (* don’t play with it). Get yours here, keep one in car for emergency. She need a P-mate?
