Out in the middle of the wilderness when you get the call of nature? Don't feel like digging and squatting over a hole? Here's the civilized way to ... uh, go: the Nature Plus Portable Toilet. Link - via Cribcandy
Of course, if you have a car, you can always use the Bumper Dumper (in our Toilet-O-Rama post)
The "Bio-Toi" is a sturdy, yet low weight portable toilet that was originally developed in cooperation with the Norwegian Armed Forces. The Bio-Toi system is now approved and used by NATO forces in many countries. The Bio-Bags (made from corn) are 100% biodegradable and 100% compostable.
