About
Eztia (also known as Eztia Materials) develops proprietary water-activated cooling technology for wearables and materials science applications. Their flagship product, HydraVolt, is a gel-based material that integrates into existing clothing and gear — shirts, bodywraps, headbands — and reduces skin temperature by up to 10°C for eight hours of strenuous activity. It requires no batteries, refrigeration, or electricity, recharging with any water source. Eztia targets defense, construction, sports, and cosmetics markets, and was co-founded by physician and MIT alumna Tiffany Yeh alongside materials engineers.
