Lakeland® CV55 Lightweight Washable Cooling Vest With Phase Change Insert, Universal, Khaki, Polycotton, Phase Change Cooling

Working in HazMat/protective suits can make anyone lose their cool. The phase change cool vests™ worn under these suits give the user a greater degree of comfort. In fact, it creates a climate of 58 deg F/14 deg C for up to 3 hr (depending on work environment). These vests create a cooling energy from a unique phase change material that is mechanically sealed in durable inserts. After freezing the inserts in ice water or a refrigerator for just 30 min, the vests deliver the constant cool temperature. Unlike frozen water or gel products, our phase change material maintains a consistent temperature of 58 deg F/14 deg C during its transition from a solid to a liquid. This ensures that the wearer receives a constant cooling temperature throughout the entire two to three hour period. Designed for comfort, these vests are washable and lightweight. The built-in side and shoulder adjustments provide a better fit. To suit a variety of users, the vests come in many styles, sizes and fabrics, including polycotton and fabric made with Nomex®.
