Product Spec Sheet

The Chill-Its® 6665 Evaporative Cooling Vest is made with an advanced polymer-embedded fabric to provide workers with immediate core cooling relief from the heat. This lightweight cooling vest is made of comfortable and durable quilted nylon exterior with mesh side panels for ventilation and stretch.

For best results, wear this body cooling vest over a t-shirt. A water-repellant liner keeps the interior of the vest as dry as possible when activated, though wearers should expect to feel some dampness/wetness. Available in multiple sizes and two colors (gray or hi-vis lime).

Heat-related illness continuously ranks among the top causes of worksite accidents and fatalities. Evaporative cooling technologies such as embedded polymers are a simple, effective and comfortable solution for heat stress prevention. Similar to how sweat cools the body, evaporative technologies use an external water source to draw heat away—helping to regulate body temperature while providing cool relief. When activated, this cooling safety vest is comfortable and refreshing for even the hottest days of the year.


Soak in water for 2-5 minutes to activate. The embedded polymers will retain water for up to four hours of cooling relief. Hand wash as needed and hang to dry.

Great for construction, landscaping, roofing or anyone working in the heat. It can also be used to keep cool and reduce the risk of heat stress while gardening, hiking, playing sports and more.
