Ergodyne Chill-Its 6665 evaporative cooling vest

The Ergodyne Chill-Its 6665 vest uses polymer-embedded fabric activated by soaking in cold water for two to five minutes. It provides immediate core cooling relief for workers facing outdoor heat. The quilted nylon exterior and water-repellent liner fit comfortably over a shirt. Mesh side panels add ventilation and stretch for mobility.

Replaces single-use ice packs

Unlike disposable packs, this vest remains hydrated for up to four hours and reactivates with a quick re-soak. The jump is worth it when a shift lasts longer than one cooling cycle and you need reusable relief. Hand wash and air dry to reuse multiple times across a season.

Limited by ambient humidity and airflow

Evaporative cooling depends on evaporation, so effectiveness drops in saturated air or still conditions. The vest fits chests from 38 to 42 inches and the shorter length aids movement. Expect mild dampness on the inner layer when fully activated.
