ADVANCED COOLING TECHNOLOGY

Phase Change Material Technology

Imagine a Cool Vest that maintains a comfortable temperature even in the most extreme heated environments. That's what you get with the patented phase change cooling technology utilized in Glacier Tek’s RPCM® Cool Vests. The semi-solid thermal energy storage material, known as phase change material, is designed to absorb heat generated by the wearer. It remains thermally stable at 59°F 15°C during the phase change process and helps maintain a normal body temperature for hours. 

Picture an ordinary ice or gel-cooled vest. It needs to be chilled below 0°, then maintains that freezing temperature.   Hold an ice cube against your chest and you get the picture - it's simply too cold to be comfortable. To alleviate the discomfort, insulating under-garments are needed as a barrier to the body, defeating the very purpose of a cooling vest. 

With the phase change material technology, you'll stay cool and comfortable at a temperature that feels natural to your skin and body. So comfortable in fact, that the  RPCM® Cool Vest can be worn directly against your skin without fear of frostbite, tissue damage, or discomfort.
