Wet cooling towels are all made from PVA fabric or polyacrylate-based fibers. They provide some limited area cooling for about 10 minutes, under the right conditions. Wet cooling towels lose their effectiveness: 1) when the air is very hot and dry, as they need constant re-wetting; and 2) in an extremely hot, very humid environment, the wet towels cannot evaporate.

Krazy Kool TechnologyTM System is designed to provide long lasting cold therapy all day, in any environment without constant maintenance or refreezing.

Most cooling vests are designed to cool the chest area only by insulating the individual with cold ice packs. The inherent challenge in the design is that it only targets the cardiovascular region and does not target the core body zones that are responsible for cooling: the carotid arteries and veins to the central nervous system and the brain; the axillary area under the arms; and inguinal or femoral arteries in the groin area. Another challenge with the cooling vest design is in the technology of the ice packs as they are usually sheets of small ice cubes that melt rapidly, limiting the amount of cold therapy. Also, cooling vests are not versatile and limited in application.

We considered the size and needs of varying bodies that require varying applications such as: preventative; performance and recovery; as well as protection against heat stress. Krazy Kool Technology™ System is designed to provide portable, versatile cold therapy in any environment without the constant maintenance or refreezing. 

Even slight increases in core temperature can result in slower reaction times, impair decision-making, and reduce muscle function. Professional athletes rely on a variety of cold therapy strategies to manage body temperature in extreme heat conditions: 

1. Preventative Cooling when you are slightly overworked, mild overheating or heat want to delay overheating, cool the body slightly. Target Zones: Carotid (neck);
2. Pre-Activity or Exposure Cooling Routine to lower core body temperatures before activity or entering hot or extreme conditions, can delay overheating and reduce body cooling load.  Target Zones: Carotid (neck), Chest, and Axillary (armpits);
3. Periodic Activity or Exposure Cooling Routine during activity, game or practice breaks. Target Zones: Carotid (neck), Chest and Axillary (armpits);
4. Post Activity or Exposure Recovery Routine core body zone and muscle

Target Zones: Carotid (neck), Chest, Axillary (armpits) and Inguinal (groin), then overused muscles.  

Krazy Kool Technology™ System can be taken anywhere. To maximize cold therapy time try to keep the system in a cool shaded area.  Leave it in your trunk during the day or take it with you when you are going shopping, walking, picnics in the park, to the beach, going to work or taking the kids to school. If you work or spend significant time outdoors, in hot humid conditions or extreme heat, implementing cooling routines with the Krazy Kool Technology™ System is critical in staying safe (Preventative, Pre-Activity, Scheduled Breaks and Post-Activity Cooling). 

Athletes can integrate the Krazy Kool Technology™ System into their cooling routines:

• Football: Wear the Krazy Kool Technology™ System at practice, on the bench, and during games.
• Soccer: Wear our technology during breaks and halftime.
• Tennis: Wear Krazy Kool Technology™ for cold therapy between sets.
• Running: Sprinters and distance runners use Krazy Kool Technology™ to keep cool pre-game, warming up on the track followed by post-race.
• Cycling: Riders wear Krazy Kool Technology™ System on their necks during races and long-distance rides.
• Workout Classes and Saunas: Wear Krazy Kool Technology™ cold therapy during a long sauna session or a yoga and pilates breaks and recovery.
• Indoor Gyms and Courts: Wear the System for preventative, pre-activity, scheduled breaks and post-activity cooling.
• Inside Places with Poor or No Air Conditioning:  Wear Krazy Kool Technology™ System for preventative, pre-activity, scheduled breaks and post-activity cooling.

There are many ice packs on the market. Most freezer ice packs contain a water based gel in a plastic bag or hard plastic container.

Unlike traditional ice packs that melt in minutes, the Krazy Kool Technology™ Cold Cores are a proprietary engineered design that contains a super cold refrigerant core, phase change material and a cooling thermal gel, all sealed in a protective durable heat reflective outer layer. It is engineered to cool the air around it at a controlled consistent rate, to deliver long lasting cold therapy, without the constant need for refreezing.

Water based gel ice packs in plastic bags can fully melt within minutes and phase change ice packs might last an hour or so.

The projected thaw rating for Krazy Kool Technology™ Cold Cores, with continuous unprotected exposure is 4-5 hours to reach 32F/0C, at room temperature. The Cold Cores were designed with its own custom, cold retention pouch to extend available stored cold therapy for an added 6-8 hours prior to full exposure at 74F/23C, consequently giving the user all day cold therapy. 

(Note: We cannot guarantee the actual thaw time, as actual conditions vary see product legal disclaimer.)

Where dry instant ice packs are 35F/2C and last 5 minutes, and freezer ice packs freeze at various temperatures below freezing, depending on your freezer limitations, Krazy Kool Technology™ Cold Cores were designed to reach or go below -18C/0F.  Basically, the colder your settings on your freezer, the colder Cold Cores will get, and the longer they are kept in the freezer, the longer they will last. 

Yes. Simply freeze the “Cold Cores” for at least 12 hours. In the morning or when going outdoors for an extended period of time, pack the Cold Cores, Temperature Regulator and Hyper-Evaporative Shell in their respective pouches and put all the components into the portable thermal carry bag.

When ready to use: 1) Lay flat the Krazy Kool Technology™ Hyper-Evaporative Shell; 2) Unzip the shell, move the fabric away to expose all the fastener straps; 3) Place the four (4) “Cold Cores” in the Krazy Kool Technology™ Temperature Regulator; 4) Lay the Temperature Regular with the cold cores flat on the Hyper-Evaporative shell; 5) Tightly secure with the fastener straps and zip close the Hyper-Evaporative shell. 

The system’s main components (cold cores, regulator, hyper-evaporative shell) are constructed from durable materials for everyday use. The recommended freeze time is 12 hours. For everyday continuous availability, freeze an additional 4 Cold Cores to alternate daily, for each system.

The main components of the Krazy Kool Technology™ Core Core: super cold refrigerant core; phase change material; and the cooling thermal gel are all safe, non toxic, compostable materials. 

At temperatures below 32°F/0°C, any frozen material can give you frostbite, so yes Cold Cores could give you frostbite if used improperly. The Cold Cores were not designed to be used directly on bare skin. They were designed to be used as a component within the Krazy Kool Technology™ System. 

Yes. The Krazy Kool Technology™ System has been designed for versatility, convenience and affordability.

Check with your travel agent or international flight restrictions. Each Cold Core weighs approximately 12.7oz or 375mL of liquid, so any number of Cold Cores would exceed most "carry on limits". A single zone Krazy Kool Technology™ System weighs about 5lbs or 2.3kg. The Cold Cores are mainly in liquid and would be “check in” for flights.

We have developed and will be available as a pre-order, "a one time fill" Core Core for travelling, that can be carried on board a plane. Each Krazy Kool Technology™ travel Cold Core has approximately 6mL of liquid or 0.22oz, reducing the liquid contents and the total weight significantly.
