Evidence synthesis
Thermal-manikin testing found that PCM cooling rate varied with temperature gradient and coverage, while cooling duration depended on mass and latent heat.
Limitations
The study evaluated generic PCM cooling vests in hot conditions. Direct Ice Sack testing is required to establish its thermal profile.
