It carries three litres of water. That’s the headline — and, honestly, most of the story. Out in the WA heat, sipping steadily through the day is the difference between thinking straight and a thumping dehydration headache, and I’ve given myself quite enough of those already just working this whole thing out.
There’s a pocket big enough for a PLB — a personal locator beacon — which, out alone, matters even more than the water: if it all goes sideways, that little device is how someone finds me. Everything else it does, it does quietly. Did I mention it holds 3 litres of water?
