Kool Max® packs are our frozen, water-based cooling packs, and they deliver the highest level of cooling in any environment for up to 3 to 4 hours per charge. Freeze them, load them into your Kool Max® vest, wrap, or accessory, and go. They're reusable, non-toxic, and cost-effective, the right choice when you need serious cold for high heat, heavy work, or long stretches outdoors. The only requirement is access to a freezer.
Choose the pack sizes that match your product, or grab a ready-made pack set for your neck wrap, seat cushion, or other accessory. Not sure which size you need? Each vest and accessory lists the packs it uses on its own product page.
