Numerous other brands of phase change material cooling products are available on the market- all virtually identical in appearance, but they all use petroleum-based PCM technology. Glacier Tek offers RPCM®, which is Renewable Phase Change Material, the only environmentally responsible phase change technology product. It differs from every other phase change cooling vest on the market because it uses a completely non-toxic, food-based product that is not hazardous like the old-style hydrocarbon-based PCM's. RPCM® is completely harmless to people, animals, and the environment.
