CryoVest, a vest, cooling to counter the heat wave

INNOVATION. While the temperatures beat the record for the month of June, the fight against the heat is an issue for the workers on site. The company Cryo’Innov offers personal protective equipment against the thermal stress, which regulates body temperature and improves the comfort of work. Zoom.

The French company Cryo’Innov proposes to go further to protect the workers who perform physical activities in developing a garment professional who meets the technical requirements of personal protective equipment. The “CryoVest Industry” is in the form of a jacket cooling which allows its wearer to better regulate her body temperature. An idea coming from the world of sport where athletes use it for training in the summer period, especially in the equestrian world.


A weight of 1.9 kg for a time in charge of the eight accumulators of cold, “First-Ice” (four on the front and four in the back, 180 grams each), it does not interfere with the movements of the operator and preserves its mobility. The vest itself is made up of fabric fire-retardant (Nomex), with a polyester lining with aluminum foil, and also provides some lumbar support with elastic straps of 100 mm. The wraps thermal feature, according to figures from Cryo’Innov, of a capacity of 2 hours of cooling at the maximum in extreme conditions (temperature exceeding 50 °C).
