A liquid-cooled vest, cut to your body. Two circuits carry heat off the five places a body sheds it fastest, under closed-loop control — and there is not one gram of ice to carry, freeze, or replace.

duty follows core temperature, not a dial
Measured against the study above: it holds a working body within a twenty-fifth of a degree of target in a 30 °C room at under a third duty. In direct sun at 40 °C it does not — both pumps saturate and it settles about 0.8 °C high. The study shows that happening rather than hiding it.
