I purchased a carplife bivvy loo and I have to say i'm very happy with it. It's small and compact when folded in its bag. It's not really heavy to cause extra weight issues. Goes up in a few seconds with no effort. I had mine when they first came out so 18 months or more now.

one question for owners of the carplife loo - do you buy bags from carplife or have you found an alternative same size etc?

I'm not sure but maybe those green bags that you put in your food waste bin might fit, I use the smaller ones in my ablutions bucket, perfect
