Ergodyne 12000 Phase Change Cooling Vest S/m Khaki

Product Description

The ERGODYNE 12000 is a phase change cooling vest designed to reduce heat stress for workers in hot environments. It uses phase change technology to absorb body heat and maintain a cooling effect for up to 4 hours per activation cycle. The vest fits chest sizes from 32 to 40 inches and closes with a hook and loop front closure for a secure, adjustable fit. Constructed from PVC and cotton, it balances durability with wearability. Safety managers, industrial employers, and workers in construction, utilities, and similar high-heat trades rely on this type of vest as part of a heat illness prevention program.

This vest is suited for size S/M workers in outdoor and indoor high-heat applications including construction sites, foundries, warehouses, and utility work. It is worn over or under other PPE depending on the job requirement. The khaki colorway works in environments where high-visibility color is not required. Workers who need sustained cooling during extended shifts without access to shade or air conditioning benefit from the fixed 4-hour cooling window provided by the phase change insert system.

Reactivate the phase change inserts according to the manufacturer's recharge instructions, typically by soaking in cool water or placing in a refrigerator or cooler. Inspect the vest and inserts before each use for damage or leaks. Follow applicable OSHA heat illness prevention guidelines and employer PPE programs when deploying cooling vests on a job site.
