Ergodyne 6685 Dry Evaporative Cooling Vest

The Ergodyne 6685 Dry Evaporative Vest has been designed to keep wearers cool in extreme thermal work environments and hot weather, but comfortably dry compared to traditional wet evaporative technology. It is suitable for industries such as construction, fabrication, warehousing, logistics and transport.

The vest uses evaporative technology to cool down the wearer. 400–600 mL of water can be filled into the internal layers of the vest, locked in with a leak-proof cap located at the back of the garment. The water is used instead of sweat to mimic the body’s natural cooling process and help the wearer maintain a comfortable body temperature.

This cooling layer is sandwiched between external layers that stay completely dry, providing the wearer with up to three days of cooling relief without wetness.
