P-Mate with thanks (?) to Libby Hill

What, you ask, is p-mate?

The unique and original P-Mate enables woman to pee neatly while standing upright.
Once you have used it, you can't do without it. The P-Mate (also known as pmate) gives you more freedom, safety, hygiene and dignity. It was developed using the feedback from thousands of women who have tested the P-Mate internationally.
The P-Mate eliminates the need to hover over a dirty toilet seat and is the perfect solution to combat those 'less than desirable' public restroom situations and traveling emergencies.
Ideal for use during outdoor festivals, while traveling, when walking, biking, jogging, camping, skiing, boating, hunting, or when sitting or squatting is difficult due to pregnancy or other medical conditions.
Useful during just about any outdoor activity.
