In general, the QRCOOL vest is ready for use within a few minutes.
After following the activation instructions, the inner and outer side of the QRCOOL vest is dry.
The „Softcooling” of the vest feels comfortable and dry to wear. After 20-30 minutes you may have the feeling that the cooling effect has decreased, but this is because the body has adjusted to the temperature. To check the cooling effect, simply take off the cooling vest for 5 minutes and start wearing it again.
Depending of the quantity of water activation, the QRCOOL vest can cool over a period of 6-8 hours. If a longer cooling period is necessary, simply re-activate the vest within 5 minutes.
