Stable and Controlled Cooling Performance

The vest uses PCM technology to absorb excess body heat and maintain a stable cooling range. This provides a balanced cooling effect that avoids the discomfort of extreme cold while still effectively reducing heat buildup.
The cooling duration typically ranges from approximately 120 to 150 minutes, depending on environmental conditions and activity levels.
