Kool Max® Cooling Packs
When is Kool Max® the best choice?
Kool Max® Cooling Pack systems offer a very high cooling energy for a moderate cost. The packs are effective in all climates and weigh less than 5 pounds. They may be worn beneath clothing and provide cooling for up to 4 hours depending on environmental conditions.
How long will the cooling packs last?
The best thing about our Kool Max® Cooling Packs is that they can be reused over and over again. With proper care and storage, your packs should last for years. During the winter, or whenever they're not in use, it's best to store them in the freezer.
How long do the packs stay cold?
The packs will stay cold for approximately 3 to 4 hours, depending on your situation. For extended cooling, we recommend purchasing an extra set of packs (which are a great value when purchased with a vest) to change out when the packs are no longer cold. Keep the extra set in a freezer (or cooler), ready to go!
Will the packs get my clothes wet?
No. The packs are seals to prevent any leakage. Any condensation from the frozen pack will be absorbed by the vest or the wrap. 
How much does each pack weigh when frozen?
Each pack weighs 8 ounces when frozen.
How does it work?
These non-toxic, water-based packs freeze in the freezer, and provide extended cooling when they are frozen.
What are the Kool max® Cooling Packs made of?
Hey, that's our secret! But we will tell you that our Kool Max® Cooling Packs are made in Akron, Ohio of all-natural, recycled and non-toxic materials.
What are the vests made of?
The vests are made of nylon and cotton with insulated foam padding.
How do I active the packs?
Simply place the packs flat in a freezer until frozen solid.
How long will it take the packs to freeze?
This depends on freezer settings. They don't take any longer than water to freeze. For best results, store them in the freezer, so they're ready to go when you are!
If the packs burst, is the liquid toxic?
Kool Max® Cooling Packs are made of non-toxic, all-natural, and recycled materials, so it isn't harmful. If the liquid does come into contact with your skin, rinse the area with gentle soap and warm water.
Under what conditions would the packs burst?
The packs won't survive improper storage in hot conditions, so for lengthy storage, keep them in the freezer. Always place them flat in the freezer. Severe impact to the packs can cause them to burst at the seams.
Do the packs meet airline security requirements?
You cannot carry-on the packs; however, they can be in your checked baggage. It would probably be a good idea to check with your airline just in case, and to pack them in a resealable clear plastic bag.
