/ The ThermoFlow
A hot shower,
in the middle of nowhere.
Pump from a lake, a bucket or a jerry can. Three seconds later you have hot water at the temperature you set, powered by its own battery and a gas canister. No hook up, no plumbing, no compromise. Pack it down and move to the next swim.
After a long night on the bank, hot water is what gets you back in the game. On a long session, being cold, stiff and grimy is how the mistakes creep in. A hot wash resets you, and you fish sharper for it.
It packs down light enough to ride on the barrow or in the back of the van, sets to the exact temperature you want, and runs off its own battery, so you are never tied to a tap. Wherever you can carry water, you can have a hot shower. That is the whole point.
