Stearns SunShower 2.5 with 2-3 showers (Capacity- 2.5 gallons)

We have two of these, and the latest one (the subject of this purchase) shows design evolution. It has a screw-in cap for the filler (the push-in cap of the previous one was prone to leak when the shower bag started heating up), and the shower head is more sensible with a 'screw-out' shower head, as opposed to a 'pull-out' shower head, makes it a lot easier to regulate flow.

Either way, these sunshower bags are absolutely great to get a shower in the middle of nowhere, as long as the sun shines.
