LIGONIER, Ind. (Feb. 2, 2018) - Outdoor brand Marmot has launched its new flagship rain jacket, EVODry, with ECO PASSPORT® certified finishing technology from Green Theme International™ (GTI). Marmot was the first to implement Aquavent, GTI’s waterless treatment for breathable water protection.

After five years of research and testing, Aquavent was launched in January 2018. GTI’s new technology, which eliminates water usage from traditional DWR (Durable Water Repellency) finishing processes, was designed to eliminate harmful PFCs.

GTI partnered with Hohenstein Group to earn the ECO PASSPORT by OEKO-TEX® certification.

"We feel that Hohenstein's rigorous standards and efficacy makes them the gold standard in textile testing worldwide,” says GTI’s Marketing Director, Brian LaPlante. “That's why we chose Hohenstein to vet our PFC-Free chemistry for our ECO PASSPORT certification."

The ECO PASSPORT by OEKO-TEX® program can be used to assess chemical products across the textile and leather supply chain in a confidential process that confirms that the formulations and individual ingredients meet specific criteria for sustainability, safety, and regulatory compliance. Chemical formulations are checked against the extensive OEKO-TEX® list of substances of concern and then verified by laboratory evaluation to ensure that they do not contain unsafe contaminants. The ECO PASSPORT certification is part of the modular portfolio of OEKO-TEX® certifications and consumer labels used by over 10,000 companies.
