Frequently Asked Questions
Body Cooling
WHO NEEDS A COOLING VEST?
If work, leisure activities or medical conditions make you uncomfortably hot and/or affect your performance, you could benefit from a Cooling Vest.
WHAT IS HEAT STRESS?
Heat stress occurs when the body's reaction to the environment causes its core temperature to rise above safe limits. This can result in a racing heart, profuse sweating, dizziness, reduced energy and slowed reaction times. This reduces safety, decreases efficiency and lowers productivity.
What is the difference between the many different types of body cooling systems available?
There are many different cooling products available and the best one for you depends on your personal situation, activity and environment. We recommend you consult your health care professional prior to purchasing a cooling garment or system.
A summary of the systems:
Evaporative
Cooling Power: Low*
Cost: Very Low
(*depending on humidity and outside variables) |
Cold packs
Cooling Power: High Cost: Low to Medium
|
Phase Change
Cooling Power: Medium
Cost: Medium
|
Active Cooling
Cooling Power: Very High
Cost: High to Very High
|
Evaporative Cooling: These products come in an assortment of garments that fit a wide variety of locations on the body. They are soaked in water to charge special polymer materials built into the garments. As the water evaporates (sometimes over several days), the garment provides surface cooling. These systems are typically low cost and light weight.
Advantages
Low cost, light weight
works for an extended period of time
|
Disadvantages
requires wetting of garment
loses effectiveness in higher humidity |

Cold pack cooling: These products typically come in vests, neck coolers and wrist coolers. The products work by incorporating cold packs into pockets of the wraps. The cold packs are placed in a freezer or a refrigerator until ready for use and then are placed in pockets designed into the wraps. The packs will stay cold for 2 to 4 hours depending on environmental conditions.
Advantages
medium cost, no wetting required
effective for 2-4 hours, highest cooling capacity
works in all environments
adjustable cooling with more / less packs
extra packs easily carried for extended cooling
|
Disadvantages
requires access to freezer / refrigerator
requires time for packs to freeze
medium weight: 4-5 lbs. |

Phase Change Cold Pack Cooling: These products are similar to the cold pack systems only use a phase change polymer in the cold packs or the garment. This technology controls the release of temperature to a specific range through out the cooling cycle. A typical temperature is 58 degree F. Phase change cold packs may be recharged in the freezer, refrigerator or in ice water.
Advantages
charges in ice water, refrigerator, freezer
wetting not required, effective for 2-3 hours
provides moderate cooling temperature
works in all environments
extra packs easily carried for extended cooling
|
Disadvantages
Higher cost system, high cost of spare packs
Lower cooling efficentcy than cold packs
medium weight: 5-7 lbs.
medium cooling capacity |

Active Cooling: These products typically incorporate a coolant, often ice water, that is circulated from a reservoir by a pump system through channels or tubes embedded in a vest. Often a hood for the head is incorporated into the system also. The temperature of the circulating coolant usually can be adjusted. The system operates on batteries, house or car current. This type of system will provide many hours of cooling before the ice and water needs to be recharged.
Advantages
Most effective cooling - core body cooling
adjustable cooling temperature
extended cooling time between recharges
no wetting required, works in all environments
light weight garments
|
Disadvantages
very high cost system
tethered system limits mobility
requires ice water reservoir
|

How long does your product stay cold?
Our therapy cold packs are not designed to "stay cold". They are designed to stay soft and absorb heat quickly. Ice therapy requires that as much heat is drawn from the effected area within the first twenty minutes as possible. Soft-Ice® optimizes therapy by providing approximately 20 minutes of effective cold therapy.
How long will the packs last?
SoftIce® is designed to transfer heat with no chemical reactions taking place. The pack will work as long as there is no physical damage to it.

electrical outlet
• the battery must continuously charge for a minimum of four hours during its initial charge
• the LED light on the charger will indicate red when the battery is being charged and will indicate green once the batteries are
fully charged
• the battery/controller unit will display the actual battery charge status using numeric digits 0-9
0 – Completely Discharged
9 – Fully Charged
Connecting the System
• once fully charged, insert the battery/controller into the reinforced battery pocket (front,
lower, inside, left hand side)
• insert the InfraRed Heating Elements into the internal pockets and close using hook/loop closure
(the front right element will need to slide through the back pocket in order for all the heating elements to fit properly.)
• connect the InfraRed Heating Element wire into the battery/controller unit
Using the Electric Heating Vest
• push the “ON” button on the battery/controller for 1 second to turn on the system
• adjust the temperature settings by pressing the “UP” and “DOWN” arrows
• temperature specifications are as follows:
