Remove packaging

Each patch comes in a sealed pouch that can be stored at room temperature.

Keep it in your bag and bring it everywhere you go—it's there to provide cold therapy benefits whenever you need them.

Attach to skin

The patch adheres and contours to your body so that you can continue with your activities as usual.

For whole-body cooling or heat stress treatment, attach the patch to the back of your neck, chest, or inner wrist. For pain relief, place the patch directly on top of the joint or muscle that needs some TLC.

Enjoy 30 minutes of icing & 6 hours of comfort

Our HydraVolt™ material rapidly draws heat away from your skin to provide immediate relief. Temperature reduction is most significant in the first 30 minutes.

The cooling intensity decreases over time so that you can enjoy safe, effective, and long-lasting cold therapy benefits for up to 6 hours.

Peel off and add water for next use

Peel the patch off like a band-aid and store it in the pouch that it came in, until you're ready to re-use it.

Just run the patch under water and it's ready for another cycle of cooling. Because we put sustainability at the forefront of our mission, out patches are reusable up to 5 times!

Have a question?

Ask us directly

When will the Eztia CryoActive Patch be available?

We're currently developing the core material technology and aim to release the first product batch in 2023. Please subscribe to our mailing list for the latest updates!

How is this protecting our planet?

Existing cooling solutions like freezer ice packs, air conditioning, and electric fans exert demands on the power grid. By substituting electric-powered cooling methods with water-powered cooling products like Eztia's, we're decreasing energy consumption and related carbon emissions that would otherwise contribute to climate damage.

I would like to reserve multiple patches when they become available, how do I do that?

By subscribing to the Eztia mailing list, you will receive priority access to pre-orders and the official product launch. For inquiries about purchasing Eztia patches in bulk or becoming a distributor for Eztia products, please email us at (

Is this safe for children, elderly people, and individuals with medical conditions?

We use biocompatible and non-medicated materials suitable for sensitive skin and design a cooling performance that provides reliable cold therapy for the general public. Individuals with preexisting conditions that are contraindications for cold application in general—including but not limited to altered skin sensation, cold hypersensitivity, and vascular disease—should consult a medical professional prior to using an Eztia product.
