The Chill-Its 6260 Lightweight Phase Change Cooling Vest is 30–60% lighter than traditional cooling vests and is designed to keep workers cooler, safer and more productive. Its phase change cooling packs maintain a 64° F / 18° C temperature for up to two hours when activated.

Constructed with a polyester cotton-blend fabric, the vest’s adjustable slide-buckle closures around the waist provide a customized fit for different body types. The heavy-duty front zipper makes for easy on/off, while the two front zippered pockets can be used to store cell phones and other small accessories.

Phase Change Packs and Lightweight Vest are also available separately.

SIZING

The cooling vest comes in three sizes ranging from S/M to 2XL/3XL. To find your size, wrap a tape measure around the widest part of your chest, under your arms, and completely around your torso. See size chart for more information.

HOW TO ACTIVATE

Place the four removable packs in a cooler of ice water for 5 minutes; freezer for 8 minutes; refrigerator for 12 minutes; or near an air conditioner for 1 hour. Then place the recharged cooling packs in the vest pockets for hours of cooling.

WHAT IS PHASE CHANGE MATERIAL

Unlike traditional ice vests that freeze solid and become bulky and short-lived, this cooling vest harnesses the power of Phase Change Material (PCM)—an advanced technology designed to absorb and release heat at a controlled temperature. Unlike ice-based cooling, PCM cold packs stay at an optimal cooling point without the risks of ice burn or extreme cold, delivering steady, long-lasting relief in high-heat environments. No dripping, no freezing—just consistent cooling when it matters most. Learn more about Phase Change Cooling and other technologies here.

HOW TO CLEAN

The cooling pack should be washed by hand with a mild detergent and warm water. Dry with a paper towel or cloth. DO NOT machine wash or machine dry. The fabric vest is machine washable with mild soap; hang dry.

Ideal for anyone needing instant cooling relief while working or being active in warm environments, indoors or outdoors. Great for industrial settings like pulp/paper, iron/steel and foundries, as well as running, biking, yard work and more. A strong solution for those who can’t use evaporative cooling options.
