CenTemp carries cold water in an insulated hydration reservoir. When you want additional cooling, press the control switch to activate the pump.

The pump sends a small amount of cold water through the tubing to the CenTemp collar. The collar distributes the water across the neck, allowing it to flow onto the body and clothing where evaporation provides additional cooling.

You control when and how often water is delivered.

No. CenTemp is designed for short, intermittent activation.

Press the switch when you want more cooling, then release it when you've delivered enough water. You can repeat the process whenever needed.

Use clean, fresh water.

For maximum cooling, add cold water and ice to the reservoir.

Do not use sports drinks, flavored beverages, chemicals, oils, or other liquids because they may damage or contaminate the pump, tubing, and water system.

Yes, to some degree. That's part of how the system works.

CenTemp intentionally delivers water to the neck and upper body so that evaporation can provide cooling. Depending on how much water you use, your shirt or other clothing may become damp.

You control how much water is delivered with the switch.

Yes.

Instead of operating continuously, CenTemp gives you control over when water is delivered. A short press provides a smaller amount of water, while additional activations provide more cooling when you need it.

This depends on how much ice you use, the outside temperature, how frequently you activate the system, and other conditions.

Using plenty of ice and cold water in the insulated reservoir will provide the best results.

Battery life depends on how frequently and how long you operate the pump.

Yes. CenTemp uses a rechargeable battery system.

CenTemp is designed to work with many types of shirts and work clothing.

The cooling collar sits around the neck, with portions of the collar positioned so water can be directed underneath or into your clothing.

Actual performance can vary depending on the type and thickness of clothing being worn.

No.

CenTemp can be useful for many activities where people spend extended periods in hot environments, including outdoor work, recreation, motorsports, yard work, events, and other activities.

No.

CenTemp is a personal comfort and cooling product. It does not replace hydration, shade, rest breaks, appropriate clothing, workplace heat-safety procedures, or other precautions for working in hot environments.

Always follow applicable heat-safety guidelines.

CenTemp is not a medical device and is not intended to diagnose, treat, cure, or prevent heat-related illness.

Never rely on CenTemp as your only protection from heat.

If you experience symptoms such as dizziness, confusion, nausea, weakness, fainting, or severe headache while in the heat, stop what you're doing and seek appropriate assistance.

After use, empty any remaining water from the reservoir and allow the system to dry.

Periodically flush the water system with clean fresh water. The collar can be cleaned with mild soap and water and allowed to air dry completely.

Do not immerse the battery, electrical connections, switch, or other electrical components in water.

I recommend hand washing the collar with mild soap and water and allowing it to air dry.

Do not place electrical components in a washing machine or dryer.

First make sure the battery is charged, the reservoir contains water, the tubing isn't kinked, and all connections are secure.

Please see our Shipping & Returns Policy for additional information.

Unused CenTemp products may be eligible for return within the return period described in our Shipping & Returns Policy.

Because the cooling collar is a wearable product that comes into contact with the body, used, worn, or washed products generally cannot be returned unless there is a manufacturing defect.
