Annie’s Smartex Leads the Industry with World’s First OEKO-TEX® Certified Aerogel Yarn Technology

Issued by TESTEX AG, the Swiss Textile Testing Institute, this certificate confirms that our aerogel-based filament yarns meet Product Class I requirements — the strictest safety category under OEKO-TEX® STANDARD 100, reserved exclusively for baby articles designed for direct skin contact.

Why This Matters

Aerogel is renowned for its ultra-lightweight structure and exceptional thermal insulation properties, widely used in aerospace and extreme cold-weather applications. Bringing this technology into everyday textiles at a skin-safe, baby-grade level represents a significant leap forward for the industry — proving that advanced performance materials can be both innovative and completely safe for the most sensitive users.

Our Mission

At Annie’s Smartex, we believe technology should never come at the cost of safety. Our mission is to ensure every consumer — from athletes to infants — can safely enjoy the comfort, warmth, and performance that scientific innovation makes possible.

About the Certification

OEKO-TEX® STANDARD 100 is one of the world’s most trusted labels for textile safety, testing for harmful substances across every stage of production. Product Class I is the most rigorous classification, applied only to products intended for direct, prolonged contact with infant skin.
