PROTEQ is developing a Qoolvest to keep the body cool. The Qoolvest will be available as an option on our current bulletproof vests and also as a stand-alone product. The Qoolvest controls the body temperature for up to several hours. The exact duration is depending on the surrounding temperature and the wearer its activities. The vest has no moving parts and operates without the requirement of batteries. Therefore the vest does not produce any unnecessary sounds. The Qoolvest is developed for users working in warm environments. For this purpose the vest is insulated to keep the heat from outside out. Because of this insolation, the vest will be less applicable for sporting purposes, since it will not allow the heat generated by the body to exit the vest. However, when working in hot environments this insulation greatly increases the duration and cooling effect of the vest, and results in a long and lasting body temperature control.
