Color Your World

How it Works?

Design meets function

Our Kuler® technology uses yarns that are spun with our proprietary thermochromic fibers that have a preselected temperature setting in which the color change will occur. These thermochromic fibers are encased inside a polymer which enables our thermochromic yarn to be machine washed ,dried, and even bleached which is a first for mass produced thermochromic yarn.

The transformation process

We then knit our Kuler® yarn into fabric which can be used for everything from fashion apparel and sportswear, to medical textiles and bed sheets. The thermochromic properties enable our textiles to reveal logos, designs, and even display alerts within the fabric via a vibrant color change. This is all possible with only our Kuler® patent pending technology, with the only 2 energy sources being heat from the human body and ambient temperature. No batteries or wires needed.

Now Launching

Kuler® was created to monitor and display increases and decreases in body and ambient temperatures in real time. Years of painstakingly difficult research and development was needed to create the first mass produced thermochromic yarn that is machine washable, dryer safe and even bleachable while maintaining all of its color intensity and color changing accuracy.

To further advance this technology we then developed the world’s first thermochromic fabric and apparel that reveals and/or hides logos, designs, patterns, and even predetermined messages at different temperatures and times throughout the fabric. Get ready to revolutionize your fitness wardrobe with our new shirt featuring Kuler® technology! This innovative thermochromic fabric changes colors with your body and ambient temperature, revealing unique designs and messages.

Machine washable, dryer safe, and vibrant—pre-order now and stand out in the gym!
