Techniche 6529-LIMHIVIZM personal protective equipment cooling vest M 21 in

Cooling vest for high-visibility work

The Techniche 6529-LIMHIVIZM is an evaporative cooling vest made from water-repellent nylon in a high-visibility lime colour. It uses a soak-to-activate method that lowers garment temperature by 15 degrees Fahrenheit below the surrounding air. The vest is sized medium with a 21-inch length and fits chest measurements between 37 and 39 inches. A zipper closure secures the garment during active movement.

Check fit and cooling needs before ordering

Verify that the wearer's chest size falls within the 37-to-39-inch range for proper fit and effective cooling contact. The evaporative method requires access to water for soaking the vest before each use. No cooling inserts or battery packs are included with this model. Ensure the work environment allows for periodic re-soaking to maintain the 5-to-10-hour cooling window.

Sustained cooling through evaporative cycle

Under continuous use the vest maintains its temperature differential as water evaporates from the nylon liner. Performance lasts between 5 and 10 hours depending on ambient humidity and airflow. The water-repellent liner helps retain moisture for consistent output rather than a short initial burst. Cooling effectiveness gradually declines as the vest dries, requiring re-soaking to restore the full 15-degree drop.
