This "stand to pee" device is a simple silicone funnel with flexible flaps designed to avoid spills. Unlike most "realistic" looking STP's, the inner slide is smooth with no grooves to accidentally retain urine, and the exit hole is plenty large enough that it won't overfill when you pee quickly or in volume.
Forget the awkward squat - use this for convenient pee breaks when camping, hiking, daily outings and events where you don't want to sit on a public toilet.
Hold with straight side facing down, as pictured, for best results. Practice in the shower if you get nervous about it!
