Cooling Comfort

Select the cooling pack that best fits your needs. Kool Max® frozen water-based packs deliver the highest level of cooling energy and require access to a freezer. Cool58® phase change packs freeze solid at a comfortable 58°F and can be activated in a freezer, refrigerator, or container of ice water, giving you more flexibility wherever your day takes you. Both packs are non-toxic, non-flammable, and fully reusable, making them a safe cooling solution you can rely on.

A Perfect Fit, Every Time

A snug fit is essential for optimal cooling performance. The Adjustable Zipper Cooling Vest features adjustable Velcro® straps at the chest, waist, and shoulders for a comfortable, customizable fit. Once adjusted for size, the zipper-pull front makes it easy to put on every time. The clean, logo-free design can be worn over clothing or discreetly underneath uniforms or costumes.

Crafted for Comfort & Durability

The cooling vest shell is constructed of durable, 100% two-ply soft, breathable, easy-clean nylon. Cooling packs fit into insulated inner pockets lined with a comfortable fabric for added skin protection, while the insulated outer composite fabric directs cooling energy toward the body. Temperature can be further adjusted by increasing or decreasing clothing layers beneath the vest or the number of packs used.

Customizable Weight & Coverage

The use of individual, separate cooling packs means you can customize the number of packs to suit your preference and size. Need a lighter vest? Simply use fewer packs. Some find that using just the packs along the spine works well, while others prefer a full pack load. Our flexible design gives you complete control over your cooling experience.

Instructions

Cool58® cooling packs freeze solid at a moderate and comfortable 58° Fahrenheit, so they won't feel uncomfortably cold against the body. Packs can be activated without a freezer — simply submerge in ice water for up to 20 minutes, place in a refrigerator, or freeze for a quick and easy cool-down.

Kool Max® cooling packs must be frozen in a freezer until solid. Water-based and offering the highest level of cooling energy, these packs require more energy to activate than Cool58® packs but deliver greater and longer-lasting cooling power in return.
