Optimer Performance Fibers, Inc. has settled a patent and trademark infringement case against 180s regarding its Dri-release with FreshGuard product.

“Dri-release is well known in many markets as a highly effective moisture management technology brand.  This action is critical to protect our patent as well as the integrity of Dri-release products sold to trusting consumers,” says Optimer director of operations, Beth Moore.

The original complaint identified work wear shirts sold online by 180’s under its Gorgonz label as far back as 2005 that, though marked with the Dri-release with FreshGuard patent number, did not contain Dri-release yarn.  It also identified 180’s ear warmers also not made of Dri-release that were sold bearing the Dri-release with FreshGuard logo.
