For your workforce

Built for the field.

Heat illness is preventable. Eztia's cooling technology is built into workwear and replenished by sweat or water, drawing heat away from the body. It helps keep workers cooler and more comfortable through physically demanding shifts in the heat.

Eztia Cooling Technology

Cooling gel printed onto fabric. Dry to the touch.

How it works

The science of staying cool.

Evaporative cooling is not new. The material we've developed to harness it is. Eztia is a cooling gel that draws heat away from your skin and is printed onto fabric, so the clothing stays dry to the touch.

01

Heat builds

As you work, heat builds up at the skin.

02

The gel draws it away

Cooling gel on the fabric activates on skin contact and draws heat away from your body.

03

Heat is released

Moisture in the gel evaporates and carries the heat with it. The fabric stays dry to the touch.

04

Sweat or water recharges it

Sweat or water replenishes the gel, so it keeps working.

Nothing to manage: No batteriesNo powerNo refrigerationNo ice packs

When the heat is at its worst,
your crew should be at their best.

Our story

Built by a physician and materials scientist.

Eztia was founded by Dr. Tiffany Yeh, who spent her career at the intersection of human performance and extreme environments. She saw an unmet need: heat kills productivity, performance, and in some cases, people. She experienced firsthand how heat compromises people's ability to operate at their best.

So she built something new: a cooling gel that draws heat away from your skin and can be printed onto fabric to create cooling apparel. The clothing stays dry to the touch, and water replenishes the gel between uses. The result?

Cooling that moves with you.
