The Ergodyne Chill-Its 6210 is a phase change cooling vest built for hot job sites. It holds a steady 64°F at the core for up to two hours.

• Steady core cooling: Phase change packs hold a constant 64°F for two hours, so cooling stays even instead of fading like melting ice.
• Works in any climate: The packs cool without airflow, so the vest performs the same in humid heat, dry heat, indoors, or outdoors.
• Fast recharge: A cooler of ice water reactivates the packs in as little as 10 minutes, or a freezer works between shifts.
• Lightweight, adjustable fit: At under 3 pounds, the contoured vest flexes with the body, and adjustable straps let it fit under bulky PPE like Tyvek suits.
• Durable build: A nylon-coated exterior resists abrasion, holding up over years of repeated job-site use.

For anyone facing heat stress under protective gear, this vest gives steady cooling without ice, dripping, or downtime.
