How do I operate my Kelvin Jacket?

The light on the charger indicates charge level. When plugged in, it will be green and then should display red when connected to a battery that is not fully charged. Once the battery is fully charged, it will change back to green. Additionally, the battery displays its level of charge when the button on the battery is pressed. This light indicates the charge based on the picture displayed on the battery. Once charged, the battery should be plugged into the jacket from the cord located in the front left pocket. Finally, the jacket is turned on by pressing and holding the logo located on the chest of the jacket. This button should be pressed down for several seconds until the light turns on. You can then cycle through the heating levels by pressing the button lightly.

Red - High

Blue - Low

Green - Eco

To Turn off your jacket, press and hold the logo button on the chest of the jacket until the light turns off.

Why is your company named Kelvin Techstyles?

We are a textile company who delivers value to the consumer by providing an aesthetically forward approach to technologically advanced heating solutions. This is represented by the thermometric temperature scale Kelvin, and a play on the word textiles as we see our company’s progression as a smart textile platform rather than solely a clothing brand.  

What does the Kelvin Techstyles Logo Represent?

Our logo integrates the first letter of our name into an abstract interpretation of the transformation from a snowflake to a sunburst.
