Discreet on the go: No more reason for embarrassing canister moments!
You know that feeling? You're walking across the campsite with a full urine canister – and somehow every glance feels uncomfortable. Especially as a woman, you often don't want half the campsite to know about your period.
Of course, you can use an opaque (e.g., blue) urine canister—but this will prevent the fill level indicator on your composting toilet from working reliably. And who wants to risk wet feet?
Our solution: The discretion concentrate.
A few drops (5–10 are enough) into the urine canister – and the contents turn a harmless, neutral blue. This way, private matters remain private.
And don't worry: It looks like chemicals, but it's 100% harmless.
We use highly concentrated, water-based food coloring – environmentally friendly and safe to use.
