Review on Simple Shower Portable Camping by Mike Johnston

This ingenious accessory not only fits standard 1 and 2 liter drinking water bottles (delivered with two different "hoses" or straws), but also normal-sized juice bottles. The INSIDE of the connector has threads for drinking water bottles, but the OUTSIDE of the same connector has ribs that allow you to fit it into 1.5 liter OJ bottles (etc) with large necks. We don't have drinking water bottles, but we do have many juice bottles, which are more durable and infinitely reusable anyway. You have to squeeze the bottle, there is almost no leakage around this seal.
