The UroClub is a hollowed out golf club designed for you to pee into on the golf course. It looks just like a normal club, more or less, but it has a screw off top and privacy towel so you can go right in the middle of the links.
Golf can be a long game, especially if you have a slow group (or worse yet, a slow group in front of you) because everyone sucks at it. Tiger Woods can probably finish the course in 1/5 the time it takes you. So for the rest of us non-Tigers out there, a good drink on the course is necessary whether you need it to quench your thirst or to build up your beer muscles to improve your game (it really works! try it sometime).
With the UroClub in your golfbag, you can drink as much as you want without fear of having no place to let it all out. Capacity is a bit over half a liter. If you go any more than that, you’ll need to find a legit restroom or go into the woods- like everyone else does.
